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.

Wind Noise: Helpful Diagnostic Hints. Wind noise may be heard from doors, windows, and mirrors, as well as all A, B and C-pillar support trim and the Panoramic sunroof. CAUSE Poor fitment of the seals and trim in the areas mentioned above
