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.
Service Action: Program Control Units (DME). Due to less than optimal DME characteristic map data, cold engine starting performance could be unsatisfactory, leading to a customer complaint. CAUSE Unfavorable DME software
