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.

If bsd communication is disrupted, oil level sensor data is no longer received by DME. Bsd communication fault(s), after repairs are shortly set, requires removal of ignition harness from cylinder head cover. All models. No model years listed.
