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, and 2009 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 ) 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.

In the event that the High-pressure Fuel Pump of an MY 2007, 2008 or 2009 3 Series vehicle (335i/xi Sedan/Coupe/Convertible), MY 2007, 2008 or 2009 5 Series vehicle (535i/xi Sedan/Sports Wagon), MY 2008 or 2009 1 Series vehicle (135is Coupe/Convertible), MY 2009 Z4 sDrive 35i, or MY 2009 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 7 592 881). For HDP diagnostic and replacement instructions, refer to SI B12 55 06 and RA 13 51 017, found in BMW TIS.


Since Monday, October 19, 2009, a Part Replacement Authorization has been required (via submission of a TC Case) for replacement of the N54 HDP Pump on E82, E88, E89, E60, E61 and E71 vehicles. For details related to the "N54 Fuel System TC Action", refer to SI B13 08 09.
