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.

N63T AND S63T ENGINE: VALVE SEAL REPLACEMENT: This SI provides a new tool and a new procedure for the N63TU valve seals replacement.
