Review: Mercedes-Benz S212.I E-Class Estate (2010-13)

Overview

Released in January 2010, the Mercedes-Benz S212 Series I (S212.I) E-Class Estate was a five-seat, executive wagon. Manufactured in Germany, the S212 E-Class Estate range initially consisted of the E 350, with the E 250 CDI following in September 2010 (see table below). In July 2011, however, the E 250 CDI was fitted with a seven-speed automatic transmission and featured idle-stop, a self-regulating turbo compressor, optimised oil pressure control and engine belt drive; the E 350 was also replaced with the more fuel-efficient and powerful E 350 BlueEfficiency. The full range is given in the table below.

Dimensions and body

Compared to the Mercedes-Benz S211 E-Class Estate , the S212 E-Class Estate was 68 mm longer (at 4918 mm), 50 mm wider (1872 mm), 17 mm taller (1512 mm) and had a 20 mm longer wheelbase (2874 mm). Furthermore, the increased use of high-strength steel contributed to a more rigid chassis, while fuel economy was improved due to the introduction of new and upgraded engines, on-demand power steering and fuel pumps, lower rolling resistance tyres and improved aerodynamics (including variable fan louvres which controlled airflow to the engine compartment).

Suspension

Like the W212 E-Class sedan , the S212 E-Class Estate had three-link front suspension with MacPherson struts and multi-link rear suspension. The suspension also included adaptive shock absorbers (Mercedes-Benz’s ‘Direct Control’ suspension) which would automatically adapt to the prevailing driving situation by reducing damping forces when driving normally (for greater ride comfort) and providing maximum damping effect when cornering at speed or during rapid evasive actions. The S212 E-Class Estate, however, also had self-levelling rear suspension.

Safety equipment

Standard safety equipment for the Mercedes-Benz S212 E-Class Estate included dual front airbags, a driver’s knee airbag, front row pelvis airbags, front and rear side airbags, curtain airbags for the front and second row occupants, ABS, electronic brake force distribution, brake assist, electronic stability control, traction control, active front seat head restraints, front and outer rear seatbelts with pre-tensioners and load limiters, driver fatigue monitoring (‘Attention Assist’) and an ‘active’ bonnet which would automatically rise in the event of a collision to cushion a pedestrian’s impact. The E 350 was further equipped with lane departure warning (‘Lane Keeping Assist’) and blind spot monitoring (‘Blind Spot Assist’).

As standard, the Mercedes-Benz E-Class Estate was also fitted with PRE-SAFE, which anticipated and prepared for collisions by tensioning the seatbelts, adjusting the seat positions for optimal airbag deployment and closing the sunroof (if open).

Euro NCAP testing

In Euro NCAP testing , a 2010 Mercedes-Benz W212 E 220 CDI sedan received a five star safety rating which included an 86 per cent adult occupant protection rating and a 77 per child occupant protection rating. In the frontal offset impact test, there was a slight risk of serious chest and leg injury for the front occupants; maximum points were awarded in the side and pole impact tests. Under ANCAP’s methodology, this testing resulted in an adult occupant protection rating of 34.88 out of 37.

Features: Mercedes-Benz S212 E 250 CDI

Standard features for the Mercedes-Benz S212 E 250 CDI included 17-inch alloy wheels, Mercedes-Benz’s COMAND APS (Cockpit Management and Data Auto Pilot System) with a seven-inch colour display, HDD satellite navigation, voice recognition (‘Linguatronic’), a ten speaker sound system, CD/DVD player, 6GB HDD music register, MP3/WMA/AAC compatibility, auxiliary inputs (3.5mm/USB/iPod) and Bluetooth connectivity, dual-zone climate control air conditioning (‘Thermatic’), leather upholstery, power adjustable front seats, directional bi-xenon headlights with washers, LED daytime running lights, cruise control with variable limiter (‘Speedtronic’), rear parking sensors with park guidance display (‘Parktronic’), rain-sensing wipers, automatic headlights, multi-function Nappa leather steering wheel with gearshift paddles, remote central locking, power windows and heated mirrors, a height and reach adjustable steering wheel, power-operated rear sunblinds, roof rails, a cargo cover and net, first aid kit, 12 volt power outlet, trip computer, tyre pressure monitoring and an immobiliser

Inside, the E-Class Estate was fitted with a 1/3:2/3-split second row seats with a ‘quickfold’ system that enabled the seats to be folded down by pulling a cable from the load compartment. The third row of seats could also be folded flat.

Features: Mercedes-Benz S212 E 350

Relative to the E 250 CDI, The E 350 was further equipped with a six-disc CD/DVD player, three-zone climate control air conditioning (‘Thermotronic’), multi-contour front seats with memory settings, UHI (Universal Handy Interface) convenience telephony, reversing camera, power folding mirrors and automatically dimming rear view and door mirrors.

S212 E-Class Estate: Avantgarde and Elegance

The Mercedes-Benz E-Class Estate was available in Avantgarde and Elegance variants. The Avantgarde variants featured sports-oriented suspension, a high gloss black radiator grille with three chrome-tipped louvres, black ash wood interior trim and silver painted analogue dials with white faced dials; E 350 models were also fitted with 18-inch alloy wheels. The Elegance variants, however, had comfort-oriented suspension, a radiator grille with four silver painted louvres and burr walnut wood trim.

Review: Mercedes-Benz S212.II E-Class Estate (2013-16)

Overview

Released in June 2013, the Mercedes-Benz S212 Series II (S212.II) E-Class Estate range initially consisted of the E 200 and E 250 CDI, with the E 400 following in September 2013. In addition to the revised range, the S212.II E-Class Estate introduced updated styling, an upgraded interior and a range of ‘intelligent drive’ technologies which would be shared with the W222 S-Class . Furthermore, all petrol and diesel engines had an ECO start/stop function which enabled the engine to shut down when the vehicle was stationary in traffic. The S212.II E-Class also introduced a new electromechanical Direct-Steer system which combined the speed-dependent power assistance with variable ratios across the steering angle range.

Visually, the S212.II E-Class Estate could be identified by its new headlights with partial LED lights and a single headlamp lens (full LED headlights were available as an option), redesigned bonnet, new bumpers, a ‘feature line’ which extended from the rear door to the tail light and new tail-lights with horizontally structured LEDs.

Inside, the dashboard had full-width two-part trim and could be specified in a wood or aluminium look, while new elements included a three-tube instrument cluster, a trapezoidal framed display in the head unit and an analogue clock between the two central air vents. The centre console was also redesigned and, for automatic models, omitted a gear lever as the multifunction steering wheel had a ‘Direct Select’ lever and gearshift paddles.

Safety equipment

Compared to its S212.I predecessor, standard safety equipment for the S212.II E-Class Estate was extended to include:

• Blind Spot Assist: at speeds above 30 km/h, two radar sensors in the rear bumper would monitor the driver’s blind spot and warn the driver against dangerous lane changes; and,
• Collision Prevention Assist (radar-based collision warning with adaptive Brake Assist): operated at speeds between 7 km/h and 250 km/h, and could detect stationary objects when driving at speeds of up to 70 km/h. Collision Prevention Assist monitored the distance to the vehicle ahead, would provide visual and audible warning to the driver if there was a collision risk and would optimise braking power (adaptive Brake Assist) for when the driver depressed the brake pedal. At initial speeds of less than 20 km/h, Collision Prevention Assist could prevent rear-end collisions.

The E 250 CDI and E 400 were further equipped with Mercedes-Benz’s ‘intelligent drive’ assistance systems which utilised a ‘Stereo Multi-Purpose Camera’ positioned in front of the rear-view mirror. The stereo camera had two lenses set at an angle of 45 degrees and with an overall range of 500 metres, providing a three-dimensional view of the area up to 50 metres ahead of the vehicle. For these models, the standard-fit ‘Driving Assistance Package Plus’ included:

• Distronic Plus (adaptive cruise control with brake warning): an ‘adaptive’ cruise control system which used two short-range radar sensors positioned behind the front bumper to monitor the road up to 30 metres ahead, and a long-range radar located behind the radiator grille which had a range of 200 metres. Operating at speeds up to 200 km/h, Distronic Plus used an electronic control unit to analyse the information from both radar systems to calculate the engine, automatic transmission and braking parameters required for proximity control. As such, Distronic Plus could automatically apply the brakes to prevent the vehicle from becoming too close to traffic ahead (the time interval could be specified) and accelerate back to the set speed when traffic allowed. To accelerate from rest, the driver only needed to operate the Distronic stalk on the steering column or briefly depress the accelerator pedal. With Distronic Plus, automatic deceleration of up to four (4) m/s²was possible. If Distronic Plus detected that heavier braking was required, a warning light would illuminate in the instrument cluster and be accompanied by an audible warning. Furthermore, the electronic proximity control system could be activated independently of Distronic Plus at speeds over 30 km/h to alert the driver if they were approaching another vehicle too rapidly;
• Steering Assist: operating in conjunction with Distronic Plus and at speeds up to 130 km/h, Steering Assist used a stereo camera located behind the windscreen to detect road markings. If the vehicle was detected to be drifting out of its lane, Steering Assist would warn the driver and provide steering intervention to keep the vehicle in its lane;
• Pre-Safe Brake (autonomous emergency braking): using two 24 GHz sensors behind the front bumper which had a range of 30 metres and a 77 GHz radar which had a range of 200 metres, Pre-Safe Brake operated at speeds between 30 km/h and 200 km/h, and at speeds below 70 km/h if the vehicle was approaching a stationary queue of traffic. Around 2.6 seconds before the anticipated moment of impact, an audible warning would sound and a red warning would appear in the tachometer. Around 1.6 before the calculated impact, the first stage of Pre-Safe Brake would initiate partial braking autonomously with around 40 per cent of the maximum braking power (approximately four (4) m/s²); the Pre-Safe occupant protections system would also be activated. If the driver then applied the brakes, maximum braking force would be made available. If the driver failed to react, Pre-Safe Brake would – in its second stage – initiate autonomous emergency braking (i.e. maximum braking power) around 0.6 seconds before the unavoidable collision to reduce the severity of the impact;
• Pre-Safe Plus: could anticipate an imminent rear-end collision and warn the vehicle behind by flashing the tail-lights. The Pre-Safe system would then deploy occupant protection measures and apply the vehicle’s brakes to prevent secondary accidents;
• BAS Plus with Cross-Traffic Assist: used a 24 GHz radar sensor with a range of 30 metres and a 77 GHz radar sensor with a range of 200 metres to monitor the distance to the vehicle ahead and would warn the driver if there was a risk of a collision. Brake Assist Plus could detect vehicles when travelling at speeds up to 200 km/h, and stationary objects when the driver was travelling at 7 km/h to 72 km/h. Significantly, Brake Assist Plus could calculate the necessary brake force assistance to prevent a rear-end collision, build up that pressure in the braking system and provide it as soon as the brake pedal was depressed for ‘the best possible deceleration’. The Cross-Traffic Assist function could operate at speeds up to 72 km/h and used the stereo camera and radar sensors to detect traffic that was crossing in front of or behind the vehicle. If detected, the driver would receive visual and audible alerts;
• Active Lane Keeping Assist: could detect when the adjacent lane was occupied (including oncoming traffic) and prevent the driver from inadvertently exiting from the lane when it was not safe to do so by applying a corrective braking force to the wheels on one side of the vehicle; and,
• Active Blind Spot Assistance: active at speeds above 60 km/h, a corrective braking force would be applied to the wheels on one side of the vehicle if the driver attempted to change lanes when a vehicle was detected in the driver’s blind spot.

Features: Mercedes-Benz S212.II E-Class Estate

Standard features for the Mercedes-Benz S212.II E 200 included 18-inch alloy wheels, Mercedes-Benz’s ‘COMAND APS’ (Cockpit Management and Data Auto Pilot System) with a 17.8 cm TFT colour display, CD/DVD player, HDD navigation, 10 GB music storage, auxiliary inputs (USB/SD card), Bluetooth interface for mobile phone connectivity and audio streaming, voice activation (‘Linguatronic’) and internet browser, climate control air conditioning (‘Thermatic’), ‘Artico’ synthetic leather upholstery, power adjustable front seats, cruise control with variable limiter (‘Speedtronic’), a reversing camera, rear parking sensors with park guidance display (‘Parktronic’), automated steering for parallel and reverse parking (‘Active Park Assist’), rain-sensing wipers, a leather-wrapped steering wheel, 1/3 to 2/3 split and folding rear seats, remote central locking, power windows and heated mirrors with folding function, a height and reach adjustable steering wheel, electrochromatic rear view and door mirrors, ambient lighting, a 12 volt power outlet, trip computer and an immobiliser.

Beyond this, the E 250 CDI added 19-inch alloy wheels, leather upholstery, front seat memory settings, full LED headlights with adaptive high beam assist, a proximity key (‘Keyless Go’), a power adjustable steering wheel and remote boot locking.

The range-topping Mercedes-Benz E 400 Estate was distinguished by its Harman Kardon Logic 7 surround sound system, digital radio tuner (DAB+), power-operated glass sunroof and a 360-degree camera which could provide a virtual bird’s eye view of the vehicle while dynamic guide lines could assist with parking manoeuvres.

Review: Mercedes S211.I E 55 AMG (2004-06)

Overview

Released in Australia in June 2004, the Mercedes-Benz S211 Series I (S211.I) E 55 AMG was an executive wagon with seven seats. Manufactured in Sindelfingen, Germany, the rear-wheel drive S211.I E 55 AMG was powered by a 5.4-litre supercharged V8 petrol engine that was mated to a five-speed automatic transmission.

M113.990 V8 engine and supercharger

For the E 55 AMG Estate, the 5439 cc M113.990 V8 engine had a die-cast alloy block with 97.0 mm bores and a 92.0 mm stroke, cast-in Silitec cylinder liners, fracture-split forged steel connecting rods, iron-coated aluminium pistons with oil spray cooling, an alloy cylinder head, a single overhead camshaft (SOHC) per cylinder bank driven by a double-roller chain, three valves per cylinder (two intake, one exhaust) actuated by roller rockers, two-spark plugs per cylinder, a dual-length intake manifold and a compression ratio of 9.0:1. While peak torque was 700 Nm from 2650-4000 rpm, the supercharged M113 engine produced 560 Nm at 1500 rpm and 650 Nm at 2000 rpm.

Unlike its naturally aspirated predecessor, the M113 engine for the S211 E 55 AMG engine had a Lysholm-type IHI supercharger – positioned between the cylinder banks – which provided maximum pressure of 0.8 bar and had an integrated air-water charge air cooler. The supercharger had two Teflon-coated aluminium shafts which rotated at up to 23,000 rpm, pushing 1850 kg of air per hour into the combustion chambers. To minimise fuel consumption at part throttle applications, the scroll compressor only operated at certain engine speeds and load conditions, activated by an electromagnetic coupling and a separate poly-V-belt.

Compared to its naturally aspirated counterpart in the S211 E 500 , changes for the supercharged M113 engine included:

• A reinforced crankcase with stiffening ribs and side bolts;
• A precision-balanced crankshaft with modified bearings and a more resistant material;
• Unique pistons;
• Forged connecting rods;
• A revised oil supply system (including the sump, catch tray and pump) and a separate oil cooler in the right-hand wheel arch;
• Optimised cylinder heads;
• A twin-spring assembly for the valve train to increased maximum engine speed to 6100 rpm (from 5600 rpm);
• A redesigned fuel system;
• A twin-pipe exhaust system with switchover valve and 70 mm diameter tailpipes for reduced exhaust gas back-pressure; and,
• A unique engine management system.

AMG Speedshift automatic transmission

The five-speed ‘AMG Speedshift’ transmission had three selectable modes:

• In standard (‘S’) mode, the transmission would monitor driving style and adapt gearshift behavior accordingly;
• In Comfort (‘C’) mode, the transmission would shift up earlier and downshift later, encouraging a more relaxed, fuel-efficient driving style; and,
• In manual (‘M’) mode, the driver could change gears using buttons on the steering wheel. When the rated engine speed was reached, the transmission would automatically shift up; and when the vehicle came to rest, first gear would be engaged automatically.

The transmission ratios for the ‘AMG Speedshift’ transmission were 3.60 (1st), 2.19 (2nd), 1.41 (3rd), 1.00 (4th) and 0.83 (5th), while the final drive ratio was 2.65. Furthermore, the transmission had a torque capacity of 1079 Nm.

Review: Mercedes-Benz S211.II E 63 AMG Estate (2006-09)

Overview

Released in September 2006, the introduction of the Mercedes-Benz S211 Series II (S211.II) range saw the E 63 AMG replace the E 55 AMG. The S211.II E 63 AMG was powered by a naturally aspirated 6.2-litre V8 petrol engine that was mated to a seven-speed automatic transmission.

Visually, the S211.II E 63 AMG could be identified by its deeper V-shaped grille, new bumpers, front fog lights, five-spoke alloy wheels, tail-lights and door mirrors. Inside, there was a new four-spoke steering wheel (shared with the CLS-Class), climate control unit, upholstery and auto-dimming rear view mirror.

M156.982 V8 engine

Developed and hand-assembled by Mercedes-AMG in Affalterbach, Germany, the 6208 cc M156 V8 petrol engine had an aluminium-silicon alloy (AlSi7) block which had 102.2 mm bores and a 94.6 mm stroke, an aluminium-silicon alloy (AlSi17) cylinder head, a Cromax 42CrMo4V forged steel alloy crankshaft, fracture-split forged connecting rods, cylinder bores with twin-wire-arc-sprayed (TWAS) coating, Bosch 9.7 engine management system, double overhead camshafts per cylinder bank (intake cams driven by a double chain from the crankshaft and small gears on the intake cams drive the exhaust camshafts), continuously variable intake and exhaust camshafts (over a range of 40 degrees via electrohydraulic vane-type adjusters), four valves per cylinder (40 mm intake valves and 34 mm exhaust valves), bucket tappets, a magnesium variable intake manifold (with two electrically-operated internal flaps) and a compression ratio of 11.3:1.

Overview

Officially released in Australia in October 2011, the Mercedes-Benz S212 E 63 AMG was a high-performance, five-seat wagon. Manufactured in Sindelfingen, Germany, the rear-wheel drive E 63 AMG Estate was powered by a 5.5-litre twin-turbo V8 petrol engine that was mated to a seven-speed semi-automatic transmission.

M157 biturbo V8 engine

The M157 V8 engine had an aluminium block with cast-in aluminium-silicon (Silitec) cylinder liners, forged crankshaft made of 38MnS6BY steel alloy (a combination of manganese, sulphur, boron and yttrium) with eight counterweights and rotating in five main bearings, fracture-split forged connecting rods, an aluminium cylinder head, double overhead camshafts (driven by three high-performance chains), variable intake and exhaust camshaft adjustment over a range of 40 degrees via four pivoting actuators, four valves per cylinder and a compression ratio of 10.0:1. Furthermore, the M 157 had a dry weight of 204 kg, maximum engine speed of 6400 rpm and Bosch MED 17.7.3 control unit.

Significantly, the M157 engine had spray-guided direct injection with piezo fuel injectors (operating at 100 to 200 bar on a demand-related basis), a Garrett MGT2260MSL turbocharger for each cylinder bank (welded to the exhaust manifold) and air/water intercooling. For the standard E 63 AMG (386 kW), maximum charge pressure was 1.0 bar; for the E 63 AMG Performance Package (410 kW), however, maximum charge was 1.3 bar. For greater efficiency, the M157 engine had an ‘ECO start/stop system’ – which the driver could disable if desired – and multi-spark ignition whereby the spark plugs could fire multiple times during the combustion sequence for more efficient combustion.

With the M157 V8 engine, the E 63 AMG Estate could accelerate from rest to 100 km/h in 4.4 seconds, or 4.3 seconds with the AMG Performance Package. Over the ADR 81/02 test cycle, fuel consumption was 10.1 litres per 100 km.

AMG Speedshift MCT transmission

First introduced in the R230 SL 63 AMG in 2008, the seven-speed ‘AMG Speedshift MCT’ (Multi Clutch Technology) had a compact, wet start-up clutch that operated in an oil bath rather than a conventional torque converter. The AMG Speedshift transmission had four individual driving modes which the driver could select via a rotary dial:

• Controlled Efficiency, ‘C’, for softer throttle response, smooth gearshifts and early upshifts to minimise fuel consumption;
• Sport, ‘S’, for greater throttle response, higher engine speeds before upshifting, greater willingness to downshift and 20 per cent faster gearshifts;
• Sport plus, ‘S+’, for 20 per cent faster gearshifts relative to Sport; and,
• Manual, ‘M’, for maximum throttle response and gearshifts 10 per cent faster than Sport plus (as quickly as 100 milliseconds). For fast gearshifts under full loads, the engine could partially suppress individual cylinders by interrupting ignition and injection.

Other features of the AMG Speedshift transmission included:

• Automatic throttle-blipping on downshifts;
• A double-declutching function for multiple downshifts; and,
• A ‘Race Start’ function.

For the M157 engine, the gear ratios for the ‘AMG Speedshift’ transmission were 4.38 (1st), 2.86 (2nd), 1.92 (3rd), 1.37 (4th), 1.00 (5th), 0.82 (6th) and 0.73 (7th), while the final drive ratio was 2.65.

Dimensions and body

Compared to its S211 E 63 AMG Estate predecessor, the S212 E 63 AMG Estate was 6 mm shorter (at 4913 mm), 50 mm wider (1872 mm), 10 mm lower (1490 mm) and had a 20 mm longer wheelbase (2874 mm); kerb mass decreased by 3 kg to 1952 kg. Inside, cargo capacity was 695 litres with the rear seats in position, though this increased to 1950 litres when the rear seats were folded flat.

Suspension

The Mercedes-Benz S212 E 63 AMG Estate had three-link front suspension with MacPherson struts and multi-link rear suspension. The suspension featured electronically-controlled dampers (‘AMG Ride Control’) which used sensors to measure drive and brake torque, steering angle, lateral acceleration, ride height, direction of motion and body roll, with the objective of reducing the roll angle of the body. Furthermore, the driver could select from three settings:

• Comfort: for soft damping characteristics;
• Sport: on average, 40 per cent firmer than Comfort; and,
• Sport plus: provided even higher damping resistance.

The rear suspension included air springs that kept the rear of the vehicle at a constant height regardless of load (‘automatic level control’).

Compared to the standard S212 E-Class , changes for the E 63 AMG included:

• A unique steel-sprung front axle with a 56 mm wider track (relative to the W212 E 500 ), new steel spring struts, new control arms, new wheel bearings and new wheel location for additional negative camber; and,
• Rear suspension with a new subframe mounting for greater stability, AMG-specific air springs, and additional negative camber.

Steering

The Mercedes-Benz S212 E 63 AMG Estate had electromechanical speed-sensitive steering.

Safety equipment

Standard safety equipment for the Mercedes-Benz S212 E 63 AMG Estate included dual front airbags, a driver’s knee airbag, front row pelvis airbags, front and rear side airbags, curtain airbags for the front and second row occupants, ABS, electronic brake force distribution, brake assist, electronic stability control, traction control, active front seat head restraints (‘Neck-Pro’) and front and outer rear seatbelts with pre-tensioners and load limiters. Furthermore, the electronic stability control system had a ‘sport’ mode which had higher thresholds for intervention and could also be deactivated.

Additional safety technologies – fitted as standard – for the E 63 AMG Estate included:

• Mercedes-Benz’s ‘Pre-Safe’ which anticipated and prepared for collisions by tensioning the seatbelts, adjusting the seat positions for optimal airbag deployment and closing the sunroof (if open);
• Lane departure warning (‘Lane Keeping Assist’);
• Blind spot monitoring (‘Blind Spot Assist’); and,
• Driver fatigue monitoring (‘Attention Assist’).

The E 63 AMG Estate was also fitted with an ‘active’ bonnet which would automatically rise in the event of a collision to cushion a pedestrian’s impact.

Brakes

The Mercedes-Benz E 63 AMG Estate had 360 mm by 36 mm ventilated and perforated front brake discs with six-piston callipers and 360 mm by 26 mm ventilated and perforated rear discs with four-piston callipers.

Available as an extra-cost option, the AMG ceramic composite brakes were manufactured from carbon-fibre-reinforced ceramic in a vacuum at 1700 degrees Celsius. The front ceramic brake discs were 402 mm by 39 mm at the front and 360 mm by 32 mm at the rear.

Euro NCAP testing

In Euro NCAP testing , a 2010 Mercedes-Benz W212 E 220 CDI sedan received a five star safety rating which included an 86 per cent adult occupant protection rating and a 77 per child occupant protection rating. In the frontal offset impact test, there was a slight risk of serious chest and leg injury for the front occupants; maximum points were awarded in the side and pole impact tests. Under ANCAP’s methodology , this testing resulted in an adult occupant protection rating of 34.88 out of 37.

Recalls: Mercedes-Benz S212 E-Class Estate

2009-10 Mercedes-Benz S212 E-Class Estate: OM651 diesel fuel leak

In December 2010, a recall was issued for Mercedes-Benz vehicles fitted with the OM651 2.1-litre turbo-diesel four-cylinder engine that were produced between 1 November 2009 and 1 November 2010 due to possible leaking of diesel fuel from the fuel filter (PRA 2010/12193).

2014 Mercedes-Benz S212 E-Class Estate: OM651 engine oil leak

In January 2015, a recall was issued for Mercedes-Benz vehicles with the OM651 turbo-diesel engine that were available for sale during 2014. In these vehicles, the seal ring between the timing chain tensioner and the engine may leak oil – this could result in a hazard for other road users and, in extreme cases, a fire risk (PRA 2015/14509).

2012-14 Mercedes-Benz S212 E-Class Estate: potential fire risk

In March 2015, a recall was issued for Mercedes-Benz S212 E-Class Estates that were available for sale from 1 July 2012 to 1 December 2014. In these vehicles, the seal on the secondary bulkhead in the engine compartment could come loose and partially fall into the engine compartment. In extreme cases, the seal may come in contact with hot engine components and pose a fire risk (PRA 2015/14588).

2015 Mercedes-Benz S212 E-Class Estate: potential fire risk

In August 2015, a recall was issued for Mercedes-Benz E-Class Estates that were available for sale from 1 April 2015 to 1 May 2015. In these vehicles, a damaged seal may have been fitted to the secondary bulkhead in the engine compartment; this seal could come loose and partially fall into the engine compartment. If this occurred and the seal came into contact with hot engine components, it could produce a risk of fire (PRA 2015/14888).

2015-16 Mercedes-Benz S212 E-Class: fuel pump may stop operating

In November 2016, a recall was issued for Mercedes-Benz S212 E-Class vehicles that were sold in Australia from 1 October 2015 to 31 August 2016. In these vehicles, the fuel pump module wiring harness could contact the frame of the rear seat base. This could affect the operation of various fuel system components and, at worst, the fuel pump may stop operating and the engine could stall. If this occurred, the loss of motive power from the engine could pose a hazard to vehicle occupants and other road users (PRA 2016/15721).

2012-16 Mercedes-Benz S212 E-Class Estate: deployment of driver’s airbag

In February 2018, recall RC2437/A was issued for Mercedes-Benz S212 E-Class Estates that were available for sale in Australia from March 2012. If the steering column was not sufficiently grounded and the steering column switch was damaged or faulty, an electrostatic discharge could cause the driver’s airbag to deploy. If these conditions occurred, an airbag warning message in the instrument cluster display and a red airbag indicator lamp (signalling that the steering column module was damaged/faulty) would alert the driver. If the airbag deployed in the absence of a collision, it could injure and distract the driver. For the VINs of the recalled vehicles, please see PRA 2018/16572.

2009-11 Mercedes-Benz S212 E 350 Estate: actuator cam for VIM

For 2009-11 Mercedes-Benz S212 E 350 BlueEfficiency Estates, the actuator cam for the variable intake manifold (VIM) in the M272 V6 engine is susceptible to failure. Symptoms of a broken actuator cam include:

• Rough idle;
• A loss of power (particularly at low and mid-range engine speeds);
• Illumination of the check engine lights; and,
• Diagnostic Trouble Codes (DTCs) such as P2004, P2005, P2006, P2187 and P2189.

Due to the venting of oil from the PCV (positive crankcase ventilation) system, carbon deposits can accumulate on the swirl flaps inside the variable intake manifold. These carbon deposits increase the resistance on the plastic actuator cam and this can cause it to break. Other parts can also fail as a result, including the swirl flaps, the actuator mounting arms and the vacuum diaphragms.

AustralianCar.Reviews understands that the original equipment supplier for the intake manifold is Pierberg and that Mercedes-Benz’s repair involves replacing the entire intake manifold since they do not supply replacement actuator cams. However, eEuroparts.com sell intake manifold repair kits that replace the plastic actuator cam with a metal component and can be used for DIY repairs. However, the intake manifold also needs to be cleaned as part of any repair. For further information about this problem, please see:

• eEuroparts.com: Mercedes-Benz Intake Manifold Repair DIY.

Mercedes-Benz S212 E 250 CDI: OM651 injector failure

For the OM651 turbo-diesel engine, the Delphi piezo injectors that were fitted for the 125 kW to 150 kW variants (i.e. the S212 E 250 CDI BlueEfficiency) experienced a high failure rate, with failure generally occurring beyond 50,000 kilometres. If the injectors failed, the engine warning light would illuminate, the vehicle would enter ‘limp home’ mode and the engine would run unevenly. Initially, revised piezo injectors were introduced. Subsequently, however, Mercedes-Benz initiated a customer service action whereby the original Delphi piezo injectors were replaced with magnetic solenoid injectors, a new ECU was installed, a fuel return line was retro-fitted and the engine cover was changed. From around mid-2012, Mercedes-Benz ceased using piezo injectors for these engines and used magnetically-actuated solenoid injectors instead.

Mercedes-Benz S212 E 250 CDI: OM651 timing chain/tensioner wear

There have been reports of wear of the simplex timing chain and/or chain tensioner at higher mileages. Since the chain is installed on the transmission side of the engine, access is restricted and replacement is expensive.

Mercedes-Benz S212 E 350 and E 400: engine rattle noise after start-up

In December 2015, Mercedes-Benz issued Service Bulletin LI05.10-P-056435 Version 10 for Mercedes-Benz S212 E 350 and E 400 Estates that had M276 engines with the following engine numbers:

• M2768: up to engine 2768xx 30 001281; and,
• M2769: up to engine 2769xx 30 406603.

According to the Service Bulletin, the driver may hear a rattling noise after start-up – from the engine compartment – that lasts for several seconds. This noise was attributed to a lack of oil pressure in the secondary chain tensioners, though Mercedes-Benz claimed that no consequential damage was to be expected.

To fix, the secondary chain tensioners (left and right) were to be replaced and a check valve was to be installed in the oil supply bore of each secondary chain tensioner in the cylinder head (left and right).

Mercedes-Benz S211 E 240 and E 320: M112 V6 crankshaft position sensor

For Mercedes-Benz W211 E 240 and E 320 with M112 V6 engines, the engine may run rough or hesitate due to water entering the crankshaft position sensor; if so, the sensor and wiring assembly require replacement.

2005-06 Mercedes S211 E 350: M272 balancer shaft sprocket gear failure

In May 2011, Mercedes-Benz issued service bulletin LI03.30-P-050027 for Mercedes-Benz S211 E 350 Estate vehicles with M272 V6 engines which:

• Had serial numbers prior to 2729..30 468993; and,
• Were manufactured prior to October 2006.

In these vehicles, premature wear of a gear on the balancer shaft sprocket could cause the positioning of the camshafts in the right cylinder bank to be impaired (relative to the crankshaft). According to the service bulletin, this wear of the balancer shaft sprocket could cause the following symptoms:

• Illumination of the check engine light; and,
• Diagnostic trouble codes (DTCs) 1200 or 1208 stored in the ME-SFI control unit.

Owners have experienced failure of the balancer shaft sprocket gear after 95,000 kilometres, accompanied by rough running and illumination of the check engine light. From October 2006 production, a different material was used for the balance shaft sprocket.

For the M272 V6 engine, the repair procedure is as follows:

1. Remove the right front camshaft adjuster cover;
2. Check the balance shaft sprocket for wear using a flexible borescope. In rare cases, a stretched timing chain may be the reason for the DTCs if the sprocket does not exhibit any signs of wear;
3. If worn, replace the balance shaft. Note: since the balancer shaft is located inside the engine block, repairs are expensive;
4. Replace the chain tensioner (part number A272 050 01 11);
5. Change engine oil and filter;
6. Drive with engine at high load and rpm for at least 20 km;
7. Change engine oil and filter once more; and,
8. Replace the camshaft adjustment solenoids.

2006 Mercedes S211 E 500: M273 worn timing chain guide gear

In May 2011, Mercedes-Benz issued service bulletin LI03.30-P-050027 for Mercedes-Benz S211 E 500 Estate vehicles with M273 V8 engines which:

• Had serial numbers prior to 2739..30 088611; and,
• Were manufactured prior to September 2006.

In these vehicles, a worn guide gear for the timing chain could cause the positioning of the camshafts in the right cylinder bank to be impaired (relative to the crankshaft). According to the service bulletin, this wear of the balancer shaft sprocket could cause the following symptoms:

• Illumination of the check engine light; and,
• Diagnostic trouble codes (DTCs) 1200 or 1208 stored in the ME-SFI control unit.

From September 2006 production, a harder material was used for the timing chain guide wheel.

For the M273 V8 engine, the repair procedure is as follows:

1. Remove the right front camshaft adjuster cover;
2. Check the timing chain guide wheel for wear using a flexible borescope;
3. If worn, replace the guide gear (part number A273 050 06 05) of the chain drive;
4. Replace the chain tensioner;
5. Change engine oil and filter;
6. Drive with engine at high load and rpm for at least 20 km;
7. Change engine oil and filter once more; and,
8. Replace the camshaft adjustment solenoids.

Mercedes-Benz S211 E 280, E 350 and E 500: M272 and M273 cam plug oil leak

Mercedes-Benz M272 V6 and M273 V8 engines that were produced prior to June 2008 may experience oil leaks (or ‘seepage’) from the round plastic expansion plugs (‘cam plugs’) on the back of the cylinder heads. There were two different size cam plugs:

• Part number A000 998 55 90: two small expansion plugs (approximately 2.5 cm diameter); and,
• Part number A000 998 56 90: one large small expansion plug (for engines without vacuum pump).

To fix, the existing plugs were to be removed, the opening cleaned and new plugs fitted; no sealer was to be used in the installation of the new plugs. New cam plugs that were not susceptible to oil leaks were phased into production in June 2008.

2005-09 Mercedes-Benz S211 E 280 and E 350: actuator cam for VIM

For 2005-09 Mercedes-Benz S211 E 280 and E 350 Estates, the actuator cam for the variable intake manifold (VIM) in the M272 V6 engine is susceptible to failure. Symptoms of a broken actuator cam include:

• Rough idle;
• A loss of power (particularly at low and mid-range engine speeds);
• Illumination of the check engine lights; and,
• Diagnostic Trouble Codes (DTCs) such as P2004, P2005, P2006, P2187 and P2189.

Due to the venting of oil from the PCV (positive crankcase ventilation) system, carbon deposits can accumulate on the swirl flaps inside the variable intake manifold. These carbon deposits increase the resistance on the plastic actuator cam and this can cause it to break. Other parts can also fail as a result, including the swirl flaps, the actuator mounting arms and the vacuum diaphragms.

AustralianCar.Reviews understands that the original equipment supplier for the intake manifold is Pierberg and that Mercedes-Benz’s repair involves replacing the entire intake manifold since they do not supply replacement actuator cams. However, eEuroparts.com sell intake manifold repair kits that replace the plastic actuator cam with a metal component and can be used for DIY repairs. However, the intake manifold also needs to be cleaned as part of any repair. For further information about this problem, please see:

Mercedes-Benz S211 E 280 CDI: knocking or ticking noise at idle

In February 2013, Mercedes-Benz issued Service Bulletin LI03.20-P-048278 for Mercedes-Benz S211 E-Class Estates that had 3.0-litre OM642 diesel engines. For Australia, this was limited to the E 280 CDI, though affected models in international markets included the E 320 CDI and E 300 BlueTEC.

According to LI03.20-P-048278, these vehicles may exhibit an intermittent knocking or ticking noise at idle and at engine speeds up to 1500 rpm. Specifically,

• The noise would occur after a mileage of approximately 32,000 kilometres or after an oil change;
• The noise could be clearly heard in the area of the first crankshaft main bearing;
• The noise would not be present when the poly-V belt was removed;
• The noise was a pulse-like crackling that occurred at irregular intervals; and,
• 20 pulses (ticking) represented a ‘justifiable complaint’.

These symptoms were attributed to a ‘run-in effect’ or defect of the first crankshaft main bearing shells. To verify the complaint, the poly-V belt was to be removed to see if that eliminated the noise. To fix, the bearing shells of the first crankshaft main bearing were to be replaced.

Mercedes-Benz S211 E 280 CDI: OM642 engine

• Pre-2010 OM642 engines were susceptible to oil cooler leaks due to heat-related seal degradation. In 2010, Mercedes-Benz introduced more durable Viton seals which could be identified by their purple colour (the previously used seals were orange).
• The TWC temperature sensor (part no. A005 153 40 28) was susceptible to failure and was subsequently replaced with part no. A007 153 74 28. When the temperature sensor fails, the check engine light may illuminate and issue the OBD-2 diagnostic code P2031.
• The positive crankcase ventilation system vents to the inlet of the turbocharger. However, the vented air may contain too much oil to easily pass through the swirl motor valves which are downstream of the turbocharger. Once this oil and sludge begins to accumulate, the swirl motor valves may become inoperative and blow a fuse that controls other sensors which are required for the engine and emissions systems to operate properly. As a result, the vehicle will enter ‘limp home’ mode and limit engine speed to 3000rpm.

Problems and faults: Mercedes-Benz S211 E-Class Estate

• The engine may idle roughly, be hard to start or hesitate under acceleration due to moisture entering the crankshaft position sensor. If so, the sensor and wiring harness require replacement.
• The ‘brake hold’ function may stop working due to a faulty signal on the network from the battery sensor.
• The halogen headlight bulbs may burn-out prematurely due to the voltage being too high; a software revision for the control subsequently reduced the voltage from 13.2 to 12.8 volts to extend bulb life.
• Water may leak onto the fuse box if the air intake drain valve gets clogged.
• The air conditioning compressor may make rumbling or squealing noises due to a bad pulley or bearings; improved components were subsequently released.
• The alternator may not adequately recharge the battery due to a faulty internal voltage regulator.
• The air conditioning (blower) motor may stop working or only work intermittently due to an internal circuit breaker in the air conditioning (blower) motor regulator that requires replacement.
• The air conditioning may only run in one mode due to a faulty connection at the C1 connector. Furthermore, the air conditioning may only work in the emergency mode due to a poor connection at the signal acquisition module.
• If the ‘Battery – Visit Workshop’ message appears, the battery control module may need to be reset or replaced.
• The steering wheel buttons may stop working due to electrostatic discharge damaging the steering column module.
• Water and dust may enter the tail-light housings due to poor sealing of the gasket.

M156 engine (E 63 AMG): cylinder head bolt failure

For 6.2-litre M156 engines with engines numbers up to 1569xx 60 060658 (corresponding to engines produced from 2006 to the first half of 2010), the cylinder head bolts can stretch and snap.

The M156 engine has ‘torque to yield’ bolts which are designed to achieve a specific clamping pressure by being tightened to a specific torque and then turned a specific number of degrees. To achieve the intended clamping pressure, the upper section of the bolts is designed to stretch slightly. While the exact cause is unclear, it has been suggested that the design of the bolts, their metallurgy or corrosion causes them to stretch and snap.

The failure of one head bolt puts additional stress on the other bolts, causing further failures. The loss of clamping pressure allows coolant and oil to enter the combustion chamber; coolant can also be forced up through the failed head bolt locations into the top of the heads, causing white smoke and a rough idle. In severe cases, the cylinders can experience hydro lock, causing the piston to seize and destroying the entire engine.

Symptoms of head bolt failure are:

• Repeated low coolant levels;
• High oil level (from coolant getting into the oil);
• Illumination of the check engine light (CEL); and,
• White exhaust smoke (burning oil).

To test for head bolt failure, the coolant system could be pressurised and allowed to sit over night to see if the coolant level had dropped and if coolant was present in the oil.

In April 2011, Mercedes-Benz issued service bulletin LI01.30-P-051567 regarding broken cylinder head bolts for the M156 engine which caused coolant to enter the engine oil and/or the combustion chamber. The service bulletin identified the following symptoms:

• CEL (Check Engine Light) illumination;
• Misfire;
• Rough running; and,
• Low coolant indicator illumination.

To fix, the cylinder heads had to be removed so that the piston deck height could be measured. If the measurement from the top surface of the crankcase to the top surface of the piston was outside of specification (the maximum deck height was 0.23 mm), then the affected connecting rod with piston and bearings had to be replaced. As part of the repair, all cylinder head bolts and hydraulic tappets were to be replaced.

M156 V8 engine (E 63 AMG): camshaft lobe and valve lifter wear

In a US class action – CEDRIC CHAN v. DAIMLER AG, MERCEDES-BENZ, MERCEDES-BENZ USA, LLC and MERCEDES-AMG GMBH – it was alleged that the combination of nodular cast iron camshafts and valve lifters made of 9310-grade steel resulted in premature wear of the M156 engine as a result of:

• the soft camshaft metal, and/or
• improper heat treating, and/or
• improper camshaft offset.

Specifically, the camshafts were designed so that the lobes would contact the valve lifters. When the camshaft lobes experienced wear, the surface would become rough or scored and no longer make contact with the lifters with the same precision – this would cause the lifters to wear prematurely, demonstrated by a gouged ring in the top of the valve lifter. The gouged ring wear on the buckets also indicated that the buckets were not spinning as intended. The result of this premature wear would be serious engine failure.

Symptoms of camshaft lobe and valve lifter wear include rattling or clattering noises on start-up. In service bulletin S-B 05.20/20b (produced in 2009), Mercedes-Benz acknowledged the problem of camshaft and valve tappet wear. Ultimately, the class action did not proceed due to the plaintiffs’ lack of standing.

Problems and faults: Mercedes S211 E 55 and E 63 AMG

• The engine may idle roughly, be hard to start or hesitate under acceleration due to moisture entering the crankshaft position sensor. If so, the sensor and wiring harness require replacement.
• The ‘brake hold’ function may stop working due to a faulty signal on the network from the battery sensor.

Recalls: Mercedes S212 E 63 AMG Estate

2012-14 Mercedes S212 E-Class Estate: potential engine fire

In March 2015, a recall was issued for Mercedes-Benz S212 E-Class vehicles that were available for sale from 1 July 2012 to 1 December 2014. In these vehicles, the seal on the secondary bulkhead in the engine compartment could come loose and partially fall into the engine compartment. In extreme cases, the seal may come in contact with hot engine components and pose a fire risk (PRA 2015/14588).

2012-13 Mercedes-Benz S212 E 63 AMG Estate: deployment of driver’s airbag

In February 2018, recall RC2437/A was issued for Mercedes-Benz S212 E 63 AMG Estates that were available for sale in Australia from March 2012. If the steering column was not sufficiently grounded and the steering column switch was damaged or faulty, an electrostatic discharge could cause the driver’s airbag to deploy. If these conditions occurred, an airbag warning message in the instrument cluster display and a red airbag indicator lamp (signalling that the steering column module was damaged/faulty) would alert the driver. If the airbag deployed in the absence of a collision, it could injure and distract the driver. For the VINs of the recalled vehicles, please see PRA 2018/16572.

Mercedes S212 E 63 AMG (M157 engine): rattle noise after start-up

In December 2015, Mercedes-Benz issued Service Bulletin LI05.10-P-056435 Version 10 for Mercedes-Benz S212 E 63 AMG Estates that had M157 engines with engine numbers up to 1579xx 60 047752.

According to the Service Bulletin, the driver may hear a rattling noise after start-up – from the engine compartment – that lasts for several seconds. This noise was attributed to a lack of oil pressure in the secondary chain tensioners, though Mercedes-Benz claimed that no consequential damage was to be expected.

To fix, the secondary chain tensioners (left and right) were to be replaced and a check valve was to be installed in the oil supply bore of each secondary chain tensioner in the cylinder head (left and right).
