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.

POWER WINDOW REVERSES WHEN CLOSING. When closing either of the front windows; the windows will anti-trap and reverse when approaching the fully closed position. Software sensitivity of the front window anti-trap mechanism.
