Moin, I have a defective climate condenser. Since the exchange is not quite cheap and I want to make sure that there are no follow-up costs, I would like to know, of course, if one can test the plant before the exchange so that one knows that it also works after the exchange. I was at a workshop, which meant that they can check it. Later, however, it was said that somehow it was not possible. Do you have experiences there? Something else about the history: The car was already bought with defective climate. When I picked him up, the air conditioning system was running and everything was fine. I guess she was only refilled regardless of the defective capacitor and then ran until the refrigerant was gone again. I don’t know if this is a sign that except the condenser everything is ok, or not. (Since the seller no longer exists, I can’t tear anything and stay on the problem myself… Yay) Maybe k Greetings, E.T.chen.
