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.

Delayed upshift may occur uphill in 3RD or 4TH gear. The transmission will not upshift, usually after going up a slight incline, and stays in either 3RD or 4TH gear too long. Calibraton sensitivity in the hill recognition program of the EGS transmission module. Models E83, X3. No model years listed.
