What it covers

A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.

N55 Engine Failsafe - FC 120308 Boost Pressure Control, Plausibility: Pressure Too Low Stored in DME Fault Memory. INFORMATION The customer complains the SES is illuminated and the engine has reduced power (engine failsafe mode).
