Peugeot 4007 AC control unit failure

Sounds familiar! I had similar AC unit issues with my 4007. Is the refrigerant compressor kicking in at all, or completely dead? Check for any refrigerant leak.

Good shout! How did you diagnose it? What did you do when your AC compressor failed, and did you end up with a massive bill?

Yeah, compressor completely gone. I tried topping up the refrigerant, but no dice. In the end, a garage confirmed the control unit was toast. Cost me almost a grand, 980€. Best get it checked at a workshop.

Thanks for the heads-up! Took it to a local mechanic, and you were spot on - the AC control unit was the culprit. Repair cost also hit around 980€. Cheers!
