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.
SERVICE ACTION: CHECK COOLANT FREEZING PROTECTION LEVEL: The coolant freeze point protection may be too low (coolant will freeze sooner than specified)
