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.
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.
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.
