Hello specialists, who can help me? With my 9000cse, 110 kw, Bj97 I have found today that, whether in idle or when the car is moving, there is always a ticking from the AC unit. That does not disappear very regular ticking (approx. every third second) only if I put the air conditioner on “car” or “eco”.What can I do?? Please don’t tell that you are always traveling with the setting AC. Since I can’t do anything myself I would be very grateful for a relatively clear error limitation since then the next way leads to the workshop again. Thank you in advance.
