CAS/FEM/BDC interface to the engine control unit

WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.

A secret key, protected against manipulation, is stored in the CAS/FEM/BDC control unit and in the engine control unit. From this point onwards, engine control units and CAS/FEM/BDC control units can only be replaced with control units specifically ordered for each vehicle. An EWS adjustment in the vehicle is not possible.

IMPORTANT: Trial exchange of the engine control units and the CAS/FEM/BDC control units is not possible!
