Subject: BMW emissions warranty of the High Pressure Fuel Pump (HDP) has been extended from 4 years or 50,000 miles to 10 years or 120,000 miles, whichever comes first.

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 BMW automobiles equipped with N54 engines. It is estimated 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 long cranking times or reduced engine performance (engine in failsafe mode) when the HDP malfunctions.

Correction:

In the event that the High Pressure Fuel Pump of an MY 2007/2008 3 Series vehicle (335i/xi Sedan/Coupe/Convertible), MY 2007/2008 5 Series vehicle (535i/xi Sedan/Sports Wagon), or MY 2008 1 Series vehicle (135is Coupe/Convertible) 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 replacing instructions, refer to SI B12 55 06 and RA 13 51 017, found in BMW TIS.
