Hi people have a problem with the speedometer, it shows no speed any more. I once hit the battery and then he went short but he had swung. There was nothing made (radio). Was at the factory city where they had connected the Tech 2. They meant that the distance signal is and ABS+ESP is all in order. I already changed the speedometer but without success. What could it be? Did one of you already have such a problem? The BC goes natürlich also no Unfortunately I have to go to the TÜV in Feb. otherwise it wouldn’t matter. Greetings Matthe 2000
