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.

N63R ENGINE: ENGINE OIL LEAK DIAGNOSIS AT TURBOCHARGER: An engine oil leak is found on the ground under the vehicle when parked.
