BMW F12 6-Series Convertible with I6 engine: VANOS oil leak and ‘limp home’ mode
In June 2014, a recall was issued for BMW F13 6-Series Convertibles that had N51, N52 or N55 six-cylinder petrol engines and were available for sale from 1 October 2009 to 30 April 2012. In these vehicles, the bolted connection on the housing of the variable valve timing unit (VANOS) adjustment units could become loose. If this occurred, the units may develop an internal oil leak and then no longer adjust quickly enough due to the reduced oil pressure. The vehicle’s emergency engine mode would then be activated and the engine warning light would illuminate to warn the driver. If the vehicle was being driven and slowed down or stopped unexpectedly, it would pose an accident hazard to the driver and other road users (PRA 2014/14160).
2012-17 BMW F12 6-Series Convertible: Takata airbag recall
In December 2018, a staged recall campaign was initiated for BMW ‘F Series’ models – this included 2012-17 BMW F12 6-Series Convertible vehicles. These vehicles had Takata driver’s airbags and the propellant wafers in these airbags could absorb moisture over time. In the event of airbag deployment, excessive internal pressure could cause the metal inflator housing to rupture and metallic fragments could be projected through the airbag cushion towards vehicle occupants – these fragments posed a risk of serious injury and fatality. For the VINs of the recalled vehicles, please see PRA 2018/17191.

2011-14 BMW F12 640i and 650i: ‘Service Engine Soon’, ‘Drivetrain Malfunction’ and VANOS faults
In September 2014, BMW North America issued Service Bulletin SI B12 26 14 for BMW F12 640i and 650i Convertibles that were manufactured prior to July 2014. These vehicles may exhibit the following symptoms:
- Illumination of the ‘Service Engine Soon’ warning (Malfunction Indicator Light);
- The engine may enter a reduced power mode with the ‘Drivetrain Malfunction’ message displayed; and,
- One or more VANOS faults may be stored in the DME, even though the engine is mechanically sound and no unusual noises can be heard from the VANOS area. These VANOS faults related to implausible camshaft position (intake or exhaust), the camshaft stuck situation, or the camshaft angle offset relative to the crankshaft being outside the tolerance range.
According to the service bulletin, these symptoms could be due to unfavourable Engine Position Management (EPM) parameters in the DME software. The service bulletin recommended test plans be performed using BMW’s ISTA/D diagnostics system and any VANOS hardware issues were to be corrected. After performing repairs, or if the ISTA test plan was inconclusive, the vehicle’s DME software was to be re-programmed with the latest version of ISTA/P. If further VANOS control faults occurred after the DME software was updated, further diagnosis would be required to identify its cause.
2011-12 BMW F12 650i Convertible: oil consumption and rough running
In November 2012, BMW issued Service Information Bulletin SI B11 07 12 for BMW F12 650i Convertibles that had N63 engines. According to the technical bulletin, the N63 engine may:
- Consume oil above its permitted specification;
- Run rough; and,
- White or blue smoke may be emitted from the exhaust.
The technical bulletin attributed these symptoms to engine compartment temperatures making the construction material of the crankcase ventilation connection lines and vent pipes brittle.
For BMW F12 650i Convertibles produced prior to January 2011, the crankcase ventilation connecting lines and vent pipes were to be replaced. For vehicles produced after January 2011, the crankcase ventilation connecting lines and vent pipes were to be inspected and, if loose, secured.
2011-12 BMW F12 650i Convertible: engine oil pump volume control valve leaks
In August 2012, BMW issued Service Information Bulletin SI B11 08 12 for 2011-12 BMW F12 650i Convertibles that had N63 engines. According to the technical bulletin, the engine oil pump volume control valve gasket seal ring may leak engine oil due as a result of damage to the seal ring during assembly. To fix,
- The engine oil pump volume control valve was to be removed;
- The engine oil pump volume control valve gasket seal ring (part number 07 11 9 963 473) was to be replaced; and,
- The oil pump volume control valve was to be reinstalled.
2011 BMW F12 650i Convertible: N63 high-pressure fuel pump failure
In July 2015, BMW issued Service Information Bulletin SI B13 02 15 for BMW F12 650i Convertibles that were produced from 1 January 2011 to 1 December 2011. According to the service bulletin, the high-pressure fuel pump quantity control valve could fail and this would cause:
- Reduced engine output; and,
- An engine malfunction warning.
To fix, both high-pressure fuel pumps were to be replaced.
2011-12 BMW F12 650i Convertible: N63 Customer Care Package
In January 2015, BMW issued Service Information Bulletin SI B11 06 14 for BMW F12 650i Convertibles produced from March 2011 to July 2012 that were powered by the N63B44O0 engine. This technical bulletin described the ‘N63 Customer Care Package’ which consisted of a six point check and, if necessary, the replacement of one or more of the following powertrain components:
- Hot-film air mass sensors;
- High-pressure piezo fuel injectors;
- Engine vacuum pump;
- Fuel system low pressure sensor/feed line;
- Fresh air intake turbo seals; and,
- Crankcase ventilation lines (hoses).
Issued in May 2015, Service Information Bulletin SI B11 16 14 advised that the engine timing chains should be checked for wear in conjunction with the N63 Customer Care Package. To avoid future valvetrain wear, the ECU was to be re-programmed and a shorter oil service interval (12 months/10,000 kilometres, previously 2 years/15,000 kilometres) was to be introduced via ISTA/P. Finally, the engine oil and filter were to be replaced.
Service Information Bulletin SI B11 06 14 also advised that Service Information Bulletin SI B61 30 14 (12 volt battery replacement) should also be performed if applicable. For vehicles that had undergone the N63 Customer Care Package, a service action label with the code ‘721’ was to be attached to the A-pillar.
The above inspections and replacements were to be performed at no cost to the owner, while the ‘N63 Customer Loyalty Offer’ provided incentives for owners affected by the campaign to trade-in their N63-powered vehicle.
