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.

NOISE FROM ENGINE WHEN STARTING. Noise when starting the engine. Engine making a rattling/grinding noise near the 12 volt starter motor.
