BMW service bulletin · NHTSA ID 10146627 · Apr 2017 · also written SI B11 08 17, B110817

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: REPLACE THE TURBOCHARGER COOLANT LINES (S63). The coolant lines running into the turbochargers may develop a leak over time. Material used for the coolant lines may not withstand prolonged turbocharger temperatures.
