Who can help??? As soon as it gets dark, the rear light burns to the right, and at sporatic intervals the alarm system starts. I then clamp off the battery in the evening. Next evening the same problem. Besides, the back right door does not open from the inside or from the outside, no matter at what time. Does anyone know if this can be done even without a workshop? I have the impression that my workshop understands even less of the Phaeton than I do, they always want to change whole assemblies, and that will be quite expensive in the long run. I already put 350€ in the electronics (Infotaiment) last year. Hope for pleasant answers Greeting Ritterstein
