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.

REAR WINDOW ROLLER SUNBLIND DOES NOT DEPLOY. Rear roller sunblind will not deploy properly on one or both sides. Connection points to slider or roller are broken.
