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.
Alternator drive belt broken. During normal driving, the front engine mounts allow the engine to move slightly on the front axle carrier.
