• All Engines
• N52
• N53

All Vehicles

• Oil filter housing gasket (OFHG)
• TSB – Deposits in the injection and induction system:
  • Deposits at the fuel injector’s tip – symptoms include hesitation or stumble during acceleration, loss of power, poor fuel efficiency, increased emissions, and/or CEL due to misfires
  • Carbon deposits at the valves or intake manifold ports – symptoms include loss of power, unstable and/or rough idle, increased emissions, and/or CEL due to misfires
  • Combustion Chamber Deposit Interference (CCDI) – pinging or knocking which may be mistaken for engine knock that first occurs as a cold start noise that fades as the engine reaches temperature; symptoms may also include increased emissions, poor acceleration, and engine idle speed surges

Certain Vehicles

• MY06: VANOS solenoids (fault codes 2A87 and 2A88)
• MY08 and earlier: TSB – Occasional ticking/rattling may occur on cold starts. This requires replacement of the 12 camshaft hydraulic valve lifters.
