SITUATION

BMW has become aware of a potential problem that could affect the durability of the High-pressure Fuel Pump (HDP) of certain MY 2007, 2008, 2009, and 2010 BMW automobiles equipped with N54 engines. We estimate that only a small percentage of vehicles will actually develop a problem. Vehicles affected may have the Service Engine Soon lamp illuminated with various low fuel pressure-related faults (e.g., 29DC, 29F1, 29F2, 2FBF) stored in the Engine Control Module (DME). Also, the affected vehicles may experience an extended engine starting time ("long crank") or reduced engine performance ("engine failsafe mode") when the High-pressure Fuel Pump malfunctions.

CORRECTION

In the event that the High-pressure Fuel Pump of a MY 2007, 2008, 2009, or 2010 3 Series vehicle (335i/xi Sedan, Coupe or Convertible); MY 2007, 2008, 2009 or 2010 5 Series vehicle (535i/xi Sedan or Sports Wagon); MY 2008, 2009, or 2010 1 Series vehicle (135is Coupe or Convertible); MY 2009 or 2010 Z4 xDrive 35i; and MY 2009 or 2010 X6 xDrive 35i equipped with the N54 engine exhibits the symptoms listed above, it should be replaced with the improved part (P/N 13 51 7 613 933). For HDP diagnostic and replacement instructions, refer to SI B12 55 06 and REP 13 51 017.

IMPORTANT:
[NEW] Starting on Monday, November 1st, 2010, a TC part authorization for the HDP pump replacement is NOT required.
