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.
SERVICE ACTION - CHECK REAR WINDOW: The rear window may not have been properly bonded. The rear window may not have been properly bonded to the body during production.
