DS3 AC Failure

A faulty AC control unit? I was thinking it was something with the compressor itself, since the AC won't even kick on. How did you figure out it was the control unit and not something else?

I took it to a workshop, and they ran some diagnostics. They mentioned the compressor not getting the signal to start. Turns out the control unit was kaput. Given your symptoms, I'd suggest getting it properly diagnosed. Could save you a lot of guesswork… and money!

Thanks a lot for the info! I'll take it to a trusted workshop and have them check the AC control unit. It was the root cause. The AC control unit was defective! The repair cost me 980€ I really appreciate the tip!

Sounds familiar! I had a similar AC issue with my old Opel Astra. Same symptoms – error codes, no cooling. In my case, it turned out to be a faulty AC control unit. Have you checked that?
