C4 Automatic Climate Control Issue

I had similar issues with my C4. The climate regulation went completely off, and the air conditioning didn't want to cooperate. If I remember correctly, the temperature sensor might be the culprit. But checking the wiring and connections is a good first step.

Thanks! When you say 'similar issues', was it exactly the same symptoms? And did checking the wiring solve the issue?

Yes, the symptoms were identical to yours. Unfortunately, checking the wiring did not resolve the problem for me. I would advise visiting a workshop. It could be that the sensor is defective.

Thanks for the advice! Took it to the workshop and, as suspected, the temperature sensor cable was defective. They replaced it, and the climate control is working perfectly again. Cost me 95€, but worth it to have it sorted!
