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.
TICKING NOISE FROM A-PILLAR AREA: A ticking noise is present in the A-Pillar and side mirror area when driving at speeds of approximately 40 MPH.
