Review: Porsche 987.I Cayman (2006-08)

Overview

Released in February 2006, the Porsche 987 Series I (987.I) Cayman was a mid-engined, two-seat coupe. Manufactured in Stuttgart, Germany, the rear-wheel drive 987 Cayman was initially available with either a 2.7- or 3.4-litre horizontally-opposed (or flat) six cylinder petrol engine (the Cayman and Cayman S, respectively).

Engine

The horizontally-opposed six-cylinder engines featured two-piece (vertically split) aluminium blocks, integrated dry-sump lubrication, liquid cooling, double overhead camshafts, four valves per cylinder and Porsche’s VarioCam variable intake valve timing system. The 3.4-litre engine, however, was fitted VarioCam Plus which combined variable valve timing with two-stage intake valve lift via electro-hydraulically operated switchable tappets.

Dimensions and suspension

Sharing its mid-engined platform with 987 Boxster , the Cayman also had the same headlights, front fenders, boot lid, side doors and tail-lights as its convertible counterpart. Compared to the 987 Boxster, the 987 Cayman was 1 mm shorter (at 4341 mm), the same with and 13 mm taller (1305 mm); wheelbase length was also unchanged (2415 mm).

The Cayman had MacPherson strut suspension front and rear.

Safety equipment

Standard safety equipment for the Porsche 987.I Cayman included dual front airbags, front side airbags, curtain airbags, ABS, electronic brake force distribution, brake assist, electronic stability control, traction control and front seatbelts with pretensioners and load limiters.

Features: 987 Cayman

Standard features for the Porsche 987.I Cayman included 17-inch alloy wheels, a nine speaker sound system with six-stack CD player, leather seats, power adjustable front seats, cruise control, a leather-wrapped steering wheel, front and rear fog lamps, remote central locking, power windows and heated mirrors, tinted windows, trip computer, immobiliser and a motion-sensing alarm.

The six-speed manual models were also fitted with Porsche’s Active Suspension Management Technology (PASM). With continuously adjustable shock absorbers and a pair of acclerometers, PASM offered selectable ‘Normal’ and ‘Sport’ modes. In Sport mode, the suspension lowered the car by 10 mm and activated a firmer damper control map. In its normal setting, the PASM would automatically adjust to changes in driving style, becoming firmer in response to greater dynamic forces.

Features: Cayman S

Compared to the standard Cayman, the Cayman S was further equipped with 18-inch alloy wheels and climate control air conditioning.

Review: Porsche 987.II Cayman (2009-11)

Overview

Released in March 2009, the 987 Series II (987.II) Cayman introduced improved equipment levels, more powerful front brakes, 2.9-litre engines, direct-injection for the 3.4-litre engines and seven-speed double-clutch transmissions (DCTs, or Porsche-Doppelkupplungsgetriebe, PDK).

Visually, the 987.II Cayman could be identified by its larger front intakes and twin-tube headlights. There was also greater differentiation between the variants as the S was fitted with twin tailpipes and aluminium-trimmed instruments.

Features

Compared to its 987.I predecessor, standard features for the 987.II Cayman were extended to include an MP3-compatible sound system with auxiliary inputs (USB and iPod), a six-disc CD/DVD player, satellite navigation with touchscreen display, rear parking sensors and driver’s seat memory settings.

2011 Cayman R

Based on the Cayman S, the lightweight Cayman R was released in February 2011. The Cayman R, however, had a revised exhaust system with a new head pipe and modified engine control which contributed to an increase in peak power and greater throttle response.

Compared to the Cayman S, the Cayman R was fitted with lightweight 19-inch ten-spoke alloy wheels, had a 20 mm lowered body and mass reduction measures included sports bucket seats with Alcantara, aluminium doors, reduced door trims (i.e. without storage compartments), door opening straps instead of levers and the omission of the instrument cluster cover and cupholders. As a result, the Cayman R had a DIN empty weight of 1295 kg, 55 kg lighter than the Cayman S.

The Cayman R was fitted with a rear axle differential lock with a 22 per cent locking value in traction and 27 per cent in propulsion. Furthermore, the more pronounced front spoiler lip and fixed rear spoiler reduced lift by around 15 per cent at the front axle and 40 per cent at the rear axle.

2011 Cayman S Black Edition

Released in August 2011, the Cayman S Black Edition had the same power outputs as the Cayman R and was fitted with 19-inch lightweight alloy wheels (finished in black) with wider 235/35 ZR19 front and 265/35 ZR19 rear tyres. Inside, the Black Edition featured embossed leather seats and scuff plates, directional bi-xenon headlights, daytime LED running lights, a leather dashboard lining and a ‘Sport Design’ steering wheel.

Overview

Released in Australia in late 2016, the Porsche 718 Cayman was a mid-engined, two-door coupe. Manufactured in Stuttgart, Germany, the rear-wheel drive 718 Cayman and Cayman S were powered by 2.0- and 2.5-litre horizontally-opposed petrol engines, respectively (see table below).

The Porsche 718 Cayman GTS was available to order from October 2017, with deliveries commencing in March 2018.

DDP and DDN engines

For the 718 Cayman, the 1988 cc DDP four-cylinder horizontally-opposed engine had an aluminium alloy block with a 91.0 mm bore and 76.4 mm stroke, in which the cylinder liners were coated in iron via a plasma beam (‘rotating single wire’ or RSW). Other features of the DDP engine included an aluminium alloy cylinder head with double overhead camshafts, ‘VarioCam Plus’ for variable intake and exhaust valve timing and lift, four valves per cylinder, direct injection via centrally positioned injectors at a pressure of up to 250 bar, cross-flow cooling, integrated dry sump lubrication and a compression ratio of 9.5:1. For the 718 Cayman S, however, the 2497 cc DDN engine had an extended bore of 102.0 mm. To reduce fuel consumption, both the DDP and DDN engines had an ‘auto start/stop’ function that would shut down the engine when the vehicle was stationary in traffic.

For the 718 Cayman, the turbocharger had a 50 mm diameter turbine wheel, 58 mm diameter compressor wheel and provided maximum boost pressure of 1.4 bar. For the 718 Cayman S, however, the turbocharger had a 55 mm diameter turbine wheel, 64 mm diameter compressor wheel and provided maximum charge pressure of 1.0 bar. The Cayman S also had variable turbine geometry in which adjustable vanes controlled the flow of exhaust gases onto the turbine wheels. At low engine speeds, the vanes would be nearly closed to build boost pressure and torque more quickly and, at high engine speeds, the guide vanes would open for greater flow.

The lateral air intakes behind the doors were used for induction of process air and for indirect intercooling. To reduce the temperature of the charged air, a heat exchanger was positioned on top of the engine and cooled using an auxiliary loop of the cooling system

When the Sport or Sport Plus modes were activated, the turbocharger could be ‘pre-conditioned’ in part-load situations by closing the bypass valve, retarding ignition timing and slightly opening the throttle – according to Porsche, this maintained momentary drive torque while increasing air throughput through the engine and charge pressure. When the driver applied full throttle, the higher charge pressure provided greater torque. The extent of ‘pre-conditioning’ differed according to whether Sport or Sport Plus drive modes were engaged.

The ‘Dynamic Boost’ function was activated when the driver briefly removed their foot from the accelerator pedal after full acceleration by keeping the throttle wide open and only stopping petrol injection – this prevented charge pressure from dropping completely for greater torque when the accelerator was depressed. In Normal mode, the Dynamic Boost function also improved engine response in quick throttle alternations, albeit with lesser effect.

Body and dimensions

Compared to the Porsche 981 Cayman , the 718 Cayman was 1 mm shorter (at 4379 mm) and 1 mm taller (1295 mm), though width (1801 mm) and wheelbase length (2475 mm) were unchanged. Like its predecessor, the chassis of the 718 Cayman had mixed aluminium/steel construction in which 44 per cent of the body-in-white consisted of aluminium (including the front body, floor and rear body, the doors and bootlid).

Changes relative to 981 Cayman

Relative to the Porsche 981 Cayman , the 718 Cayman could be identified by the ‘sharper profile’ for its nose, new bi-xenon headlights with integrated LED daytime running lights, ultra-slim front lights above the air intakes and larger cooling air intakes. At the rear, the 718 Cayman had a wider appearance due to the high-gloss black accent strip between the redesigned tail-lights which featured ‘three-dimensional technology and four brake spots that appeared to float freely’.

Inside, the 718 Cayman had a new upper dashboard panel, a new steering wheel design as per the 918 Spyder and an updated Porsche Communication Management (PCM) system which was fitted as standard for Australian-delivered vehicles.

Suspension and PASM

The Porsche 718 Cayman had MacPherson strut suspension front and rear. Compared to the 981 Cayman, the 718 Cayman had re-tuned suspension for better lateral rigidity and wheel tracking. Furthermore, the shock absorbers were been revised, while the springs and stabiliser bars were stiffened.

Porsche Active Suspension Management (PASM) was fitted as standard for the Cayman GTS and an extra-cost option for the Cayman and Cayman S. With continuously adjustable shock absorbers and a pair of accelerometers, PASM enabled the driver to select from Normal, Sport, Sport Plus and ‘Individual’ settings. For the 718 Cayman and Cayman GTS, PASM reduced the ride height by 10 mm; for the Cayman S, ride height was reduced by 20 mm.

Steering

The 718 Cayman had rack-and-pinion steering with electric power-assistance. Relative to the 981 Cayman, the steering for the 718 Cayman had a 10 per cent more direct ratio.

Safety equipment

Standard safety equipment for the Porsche 718 Cayman included dual front airbags, front seat-mounted thorax airbags, curtain airbags, ABS, electronic brake force distribution, brake assist, electronic stability control, traction control and front seatbelts with pre-tensioners and load limiters.

As standard, the 718 Cayman was equipped with a ‘multi-collision brake’ function which, after an initial collision, would automatically apply the brakes for controlled deceleration – this reduced vehicle speed and therefore the severity of any subsequent collision. The operation of multi-collision brake, however, could be over-ridden by the driver.

As an extra-cost option, the 718 Cayman could be specified with Porsche’s ‘Lane change assist’.

Wheels and brakes

Relative to the 981 Cayman, the rear-wheels for the 718 Cayman and Cayman S were half an inch wider. As such, the 718 Cayman had 8.0J x 18-inch front and 9.5J x 18-inch rear alloy wheels, while the Cayman S had 8.0J x 19-inch front and 10.0J x 19-inch rear alloy wheels.

The 718 Cayman had 330 mm by 28 mm vented front brake discs (with four-piston calipers) and 299 mm by 20 mm vented rear discs; the Cayman S, however, had 330 mm by 34 mm vented front brake discs.

Features: 718 Cayman and Cayman S

Standard features for the 718 Cayman included the Porsche Communication Management (PCM) including navigation module and Bluetooth mobile phone connectivity, a 150 watt sound system with eight speakers and digital radio tuner (Porsche’s ‘Sound Package Plus’), dual-zone climate control air conditioning, front sports seats with fourteen-way power adjustment and memory settings, heated seats, cruise control, bi-xenon headlights with Porsche Dynamic Light System (PDLS), dusk-sensing headlights, rain-sensing wipers, front and rear parking sensors, a leather-wrapped steering wheel with heating, remote central locking, power adjustable and heated door mirrors, power windows, a height and reach adjustable steering wheel, a wind deflector, trip computer, tyre pressure monitoring, an alarm and immobiliser.

Features: Porsche 718 Cayman GTS

Compared to the Cayman S, the Cayman GTS was fitted as standard with:

• Porsche’s Sport Chrono Package with selectable drive settings (see below);
• Porsche Torque Vectoring (PTV) with mechanical rear differential lock; and,
• Porsche Active Suspension Management (PASM) which lowered the body by 10 mm.

Inside, the Cayman GTS featured two-way power adjustable front sports seats with Alcantara centre panels, GTS logos on the headrests, and Alcantara trim for the steering wheel, centre console and armrests.

Visually, the Porsche 718 Cayman GTS could be identified by its new ‘Sport Design’ front bumper, black-tinted front light clusters and bi-xenon headlights, 20-inch wheels painted in black (satin finish) and black GTS logos at the base of the doors. At the rear, the Cayman GTS had tinted tail lights, black logos, a black lower bumper and centrally positioned black tailpipes.

Sport Chrono Package and ‘Sport Response’ button

As an extra-cost option, the 718 Cayman could be specified with a Sport Chrono Package which enabled the driver to select from Normal, Sport, Sport Plus and Individual settings; ‘Individual’ enabled the driver to separately program settings for PASM, the sport exhaust system, auto start/stop function and rear spoiler via a menu in the instrument cluster.

For models with the PDK, the Sport Chrono Package also included a ‘Sport Response’ button. Pressing the ‘Sport Response’ button prepared the engine and transmission for ‘spontaneous responsiveness’ for 20 seconds. At part-load, the wastegate of the turbocharger was closed so that charge pressure would be generated more quickly. When the ‘Sport Response’ button was pressed, the PDK would also downshift and engage a special shifting map which had higher shift points than Sport Plus.

Overview

Released in May 2013, the Porsche 981 Cayman was a mid-engined, two-door coupe. Manufactured in Osnabruk, Germany, the 981 Cayman and Cayman S were powered by 2.7- and 3.4-litre horizontally-opposed six-cylinder engines, respectively. The Cayman GTS was released in June 2014.

Engines and transmissions

Both the 2.7- and 3.4-litre engines featured direct injection, auto start/stop and variable valve timing and lift (Porsche’s ‘VarioCam Plus’) on the intake side, while the 3.4-litre engine also had a switching resonance flap that provides greater torque at low revs and a uniform torque curve.

The engines were mated to either six-speed manual or seven-speed double clutch transmissions (Porsche’s Doppelkupplungsgetriebe, or PDK). To conserve fuel, models fitted with the double clutch transmission also had a coasting function that enabled the engine to run in neutral when power was not required.

Body and dimensions

Based on the 981 Boxster platform, the 981 Cayman chassis had mixed aluminium-steel construction whereby 44 per cent of the body-in-white consisted of aluminium (including the front body, floor and rear body, the doors and bootlids). Significantly, the chassis achieved a 40 per cent increased in torsional rigidity and contributed to mass reductions of up to 30 kg according to the variant.

Compared to the 987 Cayman , the 981 Cayman was 33 mm longer (at 4380 mm), the same width (1801 mm), 11 mm lower (1294 mm) and had a 59 mm longer wheelbase (2475 mm). Furthermore, the windscreen was shifted forward and the roofline extended for greater interior space.

Suspension and steering

The 981 Cayman had MacPherson strut suspension front and rear, and introduced an electromechanical power steering system.

PASM and PTV

The Cayman was available with Porsche’s Active Suspension Management Technology (PASM) as an extra-cost option. With continuously adjustable shock absorbers and a pair of accelerometers, PASM offered selectable ‘Normal’ and ‘Sport’ modes. In Sport mode, the suspension was lowered and a firmer damper control map was activated. In its normal setting, the PASM would automatically adjust to changes in driving style, becoming firmer in response to greater dynamic forces.

Porsche Torque Vectoring (PTV) was also available as an option and consisted of a mechanical rear axle differential lock which could brake the inside rear wheel when cornering for more accurate handling. The differential lock had an asymmetric locking action of 22 per cent in traction and 27 per cent in propulsion.

Safety equipment

Standard safety equipment for the 981 Cayman included dual front airbags, front side airbags, curtain airbags, ABS, electronic brakeforce distribution, brake assist, electronic stability control, traction control and front seatbelts with pretensioners and load limiters.

For models fitted with the PDK transmission, adaptive cruise control (ACC) and ‘Porsche Active Safe’ (PAS) were available as extra-cost options. The ACC system used a radar sensor to detect objects up to 200 metres ahead and would vary vehicle speed to maintain a preset distance. The PAS system used the same radar to monitor traffic and would provide warnings (visual, acoustic and applying a ‘jolt’ in the brake pedal). If the driver did not react with appropriate braking, the system could increase brake pressure up to hard braking.

Brakes

The Cayman had 316 mm by 28 mm vented front brake discs and 299 mm by 20 mm vented rear discs (both with four-piston calipers). The Cayman S, however, had 330 mm by 28 mm vented front discs.

Features: Cayman and Cayman S

Standard features for the Cayman included 18-inch alloy wheels with 235/45 front and 265/45 rear ZR18 tyres, a seven speaker sound system with a CD/DVD player, MP3-compatibility, auxiliary inputs (3.5 mm/USB/iPod), and Bluetooth connectivity, satellite navigation with a seven-inch touch screen, dual-zone climate control air conditioning, daytime LED running lights, rear parking sensors, automatic headlights, a leather-wrapped steering wheel and gear shift lever, remote central locking, power windows and heated mirrors, a 12 volt power outlet, trip computer, motion-sensing alarm and an immobiliser.

The Cayman S was further equipped with 19-inch alloy wheels with 235/40 front and 265/40 rear ZR19 tyres and bi-xenon headlights.

2014 Cayman GTS

Released in Australia in June 2014, the Cayman GTS was fitted with 20-inch black Carrera S alloy wheels with 235/35 front and 265/35 rear tyres, a unique front spoiler, black finish bi-xenon headlights with Porsche Dynamic Light System (PDLS), black gloss rear lettering and a lower rear apron.

As standard, the Cayman GTS was also fitted with Porsche Active Suspension Management (PASM, detailed below) and a Sport Chrono package which included dynamic engine mounts that could stiffen to reduce the effects of mass transfer and, for models with the PDK transmission, a Launch Control function. For models with manual transmissions, however, the Sport Chrono package included automatic declutching with downshifts in the Sport Plus drive mode.

2015 Cayman GT4

Released in Australia in the third quarter of 2015, the Cayman GT4 was powered by a 3.8-litre engine which is derived from the 991 911 Carrera S. Compared to standard Cayman, the Cayman GT4 had a 30 mm lower body, an upgraded braking package and be identified by its three distinctive inlet openings in the front mask and large fixed rear wing.

Sharing components and ‘genetic spirit’ with the 911 GT3, standard features for the Cayman GT4 included 20-inch alloy wheels, 245/35 front and 295/30 rear Michelin Pilot Sport Cup 2 tyres, sports seats upholstered in leather and Alcantara, bi-xenon headlights and Porsche’s ‘Sport Chrono Pack’ with dynamic engine mounts. As standard, the Cayman GT4 was fitted with the Porsche Torque Vectoring (PTV) system with mechanical rear limited slip differential (described in ‘PASM’ and ‘PTV’, above).

Extra-cost options for the Cayman GT4 included PCCB ceramic brakes, shell-backed seats made of carbon fibre reinforced plastic (CFRP), a custom Sport Chrono Package with a ‘Track Precision’ app, and a Club Sport Package.

May 2015 updates

In May 2015, standard features for the Cayman range were extended to include fourteen-way power adjustable front seats, heated front seats, front parking sensors and a multi-function steering wheel.

Porsche Cayman Black Edition

In October 2015, Porsche released the Cayman Black Edition which was powered by the 2.7-litre F6 engine. Compared to the standard Cayman, the Cayman Black Edition was further equipped with 20-inch ‘Carrera Classic’ alloy wheels, bi-xenon headlights with Porsche Dynamic Light System (PDLS), rain-sensing wipers, auto-dimming mirrors and aluminium side window trims. Inside, the Cayman Black Edition featured an embossed Porsche crest on the seat headrests, SportDesign steering wheel and door sill guards with the ‘Black Edition’ logo in black.

2005-08 Porsche 987 Cayman: M97 engine and Intermediate shaft bearing (IMS bearing) failure

About the Intermediate Shaft (IMS) bearing
For Porsche’s M96 and M97 engines, the timing chains are driven off opposite ends of the intermediate shaft. The suspect Intermediate Shaft bearing is located at the flywheel end of the motor and handles the majority of the load on the intermediate shaft. Due to the design of the crankcase, however, there are no internal oil passages from which pressurised engine oil can be used to lubricate this bearing.

Intermediate Shaft bearing failure
It is understood that there are two causes of Intermediate Shaft bearing failure:

• Over time, oil and contaminants may seep past the bearing seal, wash out the original lubricant and become trapped inside it – this causes the bearing to overheat, wear prematurely and eventually fracture; and,
• On early M96 engines, the centre bolt that was used to secure the IMS bearing was too weak and could snap, causing the bearing to fail.

If the Intermediate Shaft bearing fails,

• Contaminants and debris from the bearing can circulate throughout the engine. If this occurs, the engine has to be dis-assembled and rebuilt; and,
• The timing chains can disengage such that the pistons and valves collide, causing serious damage that requires the engine to be replaced.

Intermediate Shaft bearing revisions
During production of the M96 and M97 engines, the intermediate shaft was revised twice –

• Original design – M96 engine (from 1997-99 model years): a dual-row ball ball-bearing. While all M96 engines from the 1997 to 1999 model years had this dual-row ball-bearing, it continued to be used in some 2000 and 2001 engines. It has been estimated that the intermediate shaft bearing failure rates for these M96 engines is 4 to 7 per cent.
• First revision – M96 engine (from 2000-01): a single row ball-bearing with a reduced load capacity. By model year 2002, all engines used this smaller, lower capacity bearing. It has been estimated that the intermediate shaft bearing failure rates for these M96 engines is around 10 per cent.
• Second revision – M97 engine (2005-08 model years): a much larger single row bearing was introduced which had the same load capacity of the early dual-row ball bearings. This revision, however, could not be serviced without engine dis-assembly so that the IMS bearing could not be replaced as a preventative measure.

In all designs, however, Porsche continued to use a sealed ball-bearing and did not specify a service interval for their replacement.

Symptoms
The seal around the intermediate shaft cover was susceptible to leaks, but was subsequently revised. If there are oil leaks in this area, then the intermediate shaft may be failing and should be inspected immediately.

The oil filter should be regularly inspected for signs of metallic debris (from the metal balls within the bearings) that are indicative of a deteriorating IMS bearing.

Prevention
To reduce the likelihood of an IMS failure, it is recommended that:

• The engine oil be changed every 6 months or 6000-8000 kilometres. This prevents higher acid levels in the oil which can destroy the bearing seals; and,
• The vehicle be driven regularly and engine speed kept above 2500-3000 rpm. It is understood that higher engine speeds unload the IMS bearing and aid in lubrication.

For model year 1997 to 2005 engines, the IMS bearing is accessible and a replacement bearing can be installed as a preventative measure (see Pelican Parts’ IMS Bearing Replacement article); there are also a range of aftermarket options available from IMS Solution and LN Engineering.

Porsche 987 Cayman S: M97 engine and cylinder bore scoring

There have been reports of cylinder bore scoring on pre-2007 3.4-litre M97 engines (as used in the Cayman S). For this engine, it is understood that bore scoring occurs because the pressure between the piston and the cylinder is too great for the oil film to separate the thrust faces sufficiently to prevent damage. Common symptoms of bore scoring include:

• Excessive smoke on start-up;
• A ticking noise from the piston tilting and the top of the piston tapping against the cylinder head as it passed TDC; and,
• Oil consumption.

Oil pump piston

For Porsche Cayman models with the 2.7-litre flat six cylinder engine, a squealing noise when the engine is first started may be due to a problem with the oil pump piston.

Radiators

The radiators are positioned behind the front air intakes and are susceptible to stone chip damage, corrosion and becoming clogged with debris. A common modification is to fit grilles to the intakes to prevent debris from accumulating on the radiators.

Power steering pump

There have been reports of the Cayman’s hydraulic power steering pump overheating from track use; modified pumps have been issued to overcome this.

Suspension

Rattling noises from the front of the vehicle may be due to nuts on the stabiliser bar becoming loose.

Rattling tailgate

The rear tailgate may rattle due to misaligned hinges or worn seals.

Exhaust hanger

The exhaust system hanger may allow the exhaust pipe to move and point downward – if so, the clamp needs to be replaced.

Key fob

The remote central locking key fob may cease to function if repeated attempts are made to unlock the door from too far away (i.e. beyond the transponder’s range). If this occurs, the key must be resynchronized with the vehicle.

Some of the functions operated via buttons on the key fob may activate unintentionally – dealers may disable these functions and/or extend the length of time for which the buttons must be depressed to activate these functions.

Porsche 987 Cayman, Cayman S and Cayman R: seatbelt function may be restricted

In 2011, Porsche UK issued a ‘non-code action’ for Porsche Boxster S and Boxster R vehicles because ‘seat belt function may be restricted’ (NCA/2011/017); no further details were provided.

Recalls: Porsche 718 Cayman

Porsche 718 Cayman: incorrect detonators for side airbags

In February 2017, a recall was issued for Porsche 718 Cayman vehicles because the front side airbags may have been installed with incorrect detonator units. In the event that a collision caused deployment of the airbags, the airbags may not provide their intended protective effect such that the risk of injury to vehicle occupants would be increased. For the VINs of the recalled vehicles, please see PRA 2017/15871.

Porsche 718 Cayman: potential fuel leak

In February 2017, a recall was issued for Porsche 718 Cayman vehicles because the fastening screws for the fuel collection pipes could loosen and shear off. If this occurred, fuel may leak from the vehicle and the driver may notice a petrol smell. In the presence of an ignition source, the leaking fuel could cause a fire. For the VINs of the recalled vehicles, please see PRA 2017/15873.

2016-19 Porsche 718 Cayman: crash beam could damage fuel tank

In March 2019, recall campaign AKA3 was issued for Porsche 718 Cayman vehicles that were available for sale in Australia from 23 February 2016 to 14 February 2019. In a frontal collision, the lower longitudinal crash beam in the luggage compartment area could penetrate the bulkhead wall at the lower cross body component. If this occurred, the fuel tank could be damaged and leak fuel. In the presence of an ignition source, a fire could occur. For the VINs of the recalled vehicles, please see PRA 2019/17381.

2015-16 Porsche 718 Cayman: unintended airbag deployment

In September 2019, recall campaign AKB4 was issued for Porsche 982 718 Cayman vehicles that were available for sale prior to 16 June 2016. These vehicles may have been fitted with an airbag control unit that had an ‘out of specification’ capacitor for maintaining the power supply. As a result, the airbags and/or seatbelt pretensioners may deploy unexpectedly, or may fail to deploy in the event of a collision. For the VINs of the recalled vehicles, please see PRA 2019/17812.

Generally, manufacturers will inform the original buyers if their vehicle is subject to a recall and of the steps required to remedy the defect or fault. Please note that the recalls below (if any) are for Australian-delivered vehicles only. Furthermore, the number of recalls should not be taken as an indication of a model’s reliability or its safety more generally.

Recalls: Porsche 981 Cayman

2014-15 model year Porsche 981 Cayman: bonnet may open unintentionally

In November 2014, a recall was issued for 2014 and 2015 model year Porsche 981 Cayman vehicles because the lock bracket for the front cargo area may open unintentionally. If this occurred, the front cargo area/bonnet may open while driving, impairing the driver’s visibility and increasing the risk of an accident. For the VINs of the recalled vehicles, please see PRA 2014/14410.

2015-16 Porsche 981 Cayman: unintended airbag deployment

In September 2019, recall campaign AKB4 was issued for Porsche 981 Cayman vehicles that were available for sale from 23 June 2015 to 16 June 2016. These vehicles may have been fitted with an airbag control unit that had an ‘out of specification’ capacitor for maintaining the power supply. As a result, the airbags and/or seatbelt pretensioners may deploy unexpectedly, or may fail to deploy in the event of a collision. For the VINs of the recalled vehicles, please see PRA 2019/17812.

2013-14 Porsche 981 Cayman: rear suspension failure

In September 2021, recall campaign AMB7 was issued for 2013-14 Porsche 981 Cayman vehicles. Due to a manufacturing defect, the rear suspension may fail in extreme driving situations and this would result in a loss of vehicle control. Such loss of control increased the risk of serious injury or death to occupants and/or other road users, and damage to property. For the VINs of the recalled vehicles, please see REC-004963.

2013 model year Porsche 981 Cayman: ‘Fault Electric parking brake’

In April 2013, Porsche issued Technical Information Bulletin WD08 for Porsche 981 Cayman and Cayman S vehicles that had six-speed manual transmissions. In these vehicles, implausible fault entries may be stored in the electric parking brake control unit because the monitoring function was too sensitive. As a result, the yellow warning message ‘Fault Electric parking brake’ may appear on the multi-function display even though there was no system fault present. The warning message would disappear when the ignition was switched off and on again.

To fix, the electric parking brake control unit was to be re-programmed.

2013-14 Porsche 981 Cayman: multi-function display and service reminder indicator

In April 2014, Porsche issued Technical Information Bulletin WE02 for 2013-14 model year Porsche 981 Cayman vehicles. Due to a software error in the instrument cluster, these vehicles may exhibit the following symptoms:

• Failure of the multi-function display. Specifically, the display in the instrument cluster could stop working under certain conditions and start working again later; and,
• Implausible service reminders. The driver may be informed that a service is due although the mileage and date for a required service have not yet been reached.

To fix, the instrument cluster module was to be re-programmed.

Released in May 2013, the Porsche 981 Cayman was a mid-engined, two-door coupe. Manufactured in Osnabruk, Germany, the 981 Cayman and Cayman S were powered by 2.7- and 3.4-litre horizontally-opposed six-cylinder engines, respectively.

Released in Australia in March 2009, the Porsche 987 Series II (987.II) Cayman introduced improved equipment levels, more powerful front brakes, 2.9-litre engines, direct-injection for the 3.4-litre engines and seven-speed double-clutch transmissions (DCTs, or Porsche-Doppelkupplungsgetriebe, PDK). The Porsche 987.II Cayman could be identified by its larger front intakes and twin-tube headlights. There was also greater differentiation between the variants as the S was fitted with twin tailpipes and aluminium-trimmed instruments.
