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: REWORKING THE PHEV SCREW CONNECTION OF THE COOLANT LINE ON ELECTRICAL MACHINE ELECTRONICS. The screw connection of the coolant lines to the electrical machine electronics (EME) may not have been properly tightened.
