BMW service bulletin · NHTSA ID 10242698 · Aug 2023 · also written SI B54 05 21, B540521
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.
The sunroof will not operate in either direction.
