BMW service bulletin · NHTSA ID 10152662 · Nov 2018 · also written SI B17 05 18, B170518
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 TRANSMISSION OIL COOLER AND CHECK TRANSMISSION OIL COOLER LINE. The transmission oil cooler and transmission oil cooler line (radiator feed) could be affected by a manufacturing defect, which may result in transmission fluid leak.
