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.
TICKING NOISE FROM DRIVERS FOOTWELL DURING LIGHT BRAKING WHILE COASTING: A ticking sound can be heard from the drivers footwell while coasting with the engine OFF. The noise occurs when the pedal is slightly pressed with minimum force without the brake light being activated.
