Hello, at my SLK today suddenly the following error occurred (Bj. 2001, 230 Compressor) The ZV does not work anymore via the key, the inside button goes. The turn signals indicate how normal 3x when closing, 1x when opening, but it does nothing. Manual unlocking of the left door works, but the trunk, tank flap and right door are not locked. Does anyone have an idea or a solution? Thank you and Gruss Juppi
