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 ENGINE SOON (MIL) - IHKA FC 8013A3. The malfunction indictor lamp (MIL) illuminates at start-up or during trip. Heating function is usually working properly.
