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.

NO COOLING INTERMITTENTLY FROM VENTS. After a long journey (more than 30 minutes).
