Hello, my control unit is supposedly defective.Both lamps flashing, have already made the attempt with the ABS diagnostic connector and the mass – no success! To the friendly I drive still to possibly with the original diagnostic device to have the error reset.Does anyone know for a supplier for a control unit that can also be paid?Evt also a used or retreaded?Does that have something to buy?Have my doubts.Bin from the Karlsruhe area!
