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.
Low Coolant Level with No Sign of External Leaks. The Low Coolant Warning light is on and there are no signs of a visual leak. Pressure testing the cooling system may or may not show an internal leak (loss of pressure).
