Installing A New CAS Control Unit
WARNING: This page is about a different car, the 2005 BMW 645Ci and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.
- Order the new CAS control unit for the specific vehicle in question, quoting key number, VIN, standard equipment.
- Once the new CAS control unit has been encoded (DME/DDE control unit and CAS control unit mutually identified and calibrated), the engine can be started.
IMPORTANT:
Do not install a used CAS control unit.
The engine cannot be started if the CAS control unit being fitted has already been used (different vehicle identification number).
