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.

Incorrect Tightening Torques for E-Transmission. For M12 x 1.5 x 60 = 35 Nm + 90° angle of rotation ? For M12 x 1.5 x 160 = 40 Nm + 180° angle of rotation [ Copyright (c)2015 BMW of North America, Inc.
