BMW service bulletin · NHTSA ID 10152666 · Nov 2018 · also written SI B51 23 18, B512318
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: RESEAL UNDERBODY BAFFLES. Under certain conditions when driving through water, the underbody baffles may not completely prevent water ingress. Incorrect sealer application during production.
