BMW service bulletin · NHTSA ID 10233154 · Feb 2023 · also written SI B11 04 17, B110417
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.
The coolant lines routed to the exhaust turbochargers may develop an external coolant leak.
