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 is leaking from under the car which is equipped with the S63 engine. A low coolant warning might also be displayed (CC Message ID166).
