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.

A more robust sensor was developed due to selective catalyst reduction (SCR) active tank failing, because of temperature sensor, and is integrated into active tank.
