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.
SUNROOF REVERSES WHEN CLOSING: The sunroof reverses direction (anti-traps) just as the sunroof glass meets the wind deflector. The sunroof may not properly initialize as a result.
