Installing a new CAS control unit
Order the new CAS control unit for the specific vehicle in question, quoting model code number, vehicle identification number, standard equipment. Once the new CAS control unit has been programmed and encoded (DME/DDE control unit and CAS control unit mutually identified and adjusted), 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).
