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: Program Control Units. When coming to a stop, there is the possibility of an unfavorable judder. This is due to the software parameters for downshifting and transmission clutch control. CAUSE Unfavorable vehicle software
