Hello together, have just changed my battery in the key and to get the orange error message “Battery weak etc.” away in the display once started the vehicle with key in the ignition lock. Error message elemeniert! So far, so good! Then I got the idea to lock the car with the key in the lock driver door sometimes (use otherwise only Keyless). Ging also. DWA turns on, everything well. Now I also wanted to unlock it once with key in the lock driver door. Ging also, DWA stayed on. (???) door opened and my car horned at me… to get scared of death and hecticly pressed on all buttons of the lock. Auto horned no more, DWA deactivated. Kreidebleich took the BA and ‘n Schnaps out of the cabinet, studied, drunk and found nothing of the like that. Schnaps and BA re-packed away again. Please repeat again to Phaetonforum search and also found nothing. Überlegt schnaps zu zu erholfen… idea then again rejected. Again Düßem Düßels was kept shut away?
