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.

RAISING OF WIND DEFLECTOR AT A HIGH SPEED. Unintentional lifting of the wind deflector occurs at a high speed and it is perceived that it may possibly detach. CAUSE Rear seat backrest not locked. This is not visually detectable at first glance. Make the customer aware of the proper rear seat engagement.
