BMW service bulletin · NHTSA ID 10041281 · Nov 2010 · also written SI B63 14 10, B631410

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 rear lamp is not water tight due to cracks due to stress. Water may enter the lamp.
