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.
COOLANT LEVEL CHECK AND TOP-OFF AT SECOND OIL SERVICE: A new, additional coolant level check task is now linked to the second engine oil service (Service Counter 2 only). The scope of maintenance work will display in ISPA Next that applies to the high-temperature circuit.
