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.
N51, N52K and N52T: Idle Fluctuation During Engine Warm-up Phase. After a cold engine start, the idle speed may be unstable or start fluctuating up and down slightly while the vehicle is stopped.
