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.
THERMOSTAT FAULTS (B-ENGINES). The Service Engine Soon light is on. A Check Control message for ""Engine overheated"" and or ""Exercise caution!"" may also display.
