NOTE: Procedure in case of defective control unit!

If the CAS, EWS (only E83) or DME/DDE is defective, a certain procedure must be followed. The required control unit must be ordered to match the vehicle exactly. For this, the vehicle data (vehicle identification number) is required. An EWS adjustment is not necessary after renewing the control unit.> E70 Adjustment is necessary if the electronic transmission control is replaced. For adjustment, the CAS control unit transmits an individual code to the EGS control unit. This individual code is required for the authentication procedure for enabling the transmission function.
