BMW service bulletin · NHTSA ID 10037010 · Jul 2010 · also written SI B11 08 03, B110803
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.
Six different models equipped with the M54 engine could have valve covers break in cold weather and ruin the engine. This is due to moisture accumulation.
