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.
BUZZING NOISE FROM VALVETRONIC MOTOR BEFORE OR AFTER ENGINE OPERATION: Buzzing noise may be heard from the Valvetronic motor when the vehicle is unlocked, before the engine is started, or after the engine is turned off.
