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.

INNER DOOR WEATHER STRIP SEPARATING. The rear section of the inner door weather strip may be separating at the bonded seam. Insufficient bonding at the inner door weather strip seam.
