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.

There may be excessive cranking before the vehicle starts. The service engine soon light may also be on with a lack of engine power.
