Peugeot 807 AC Failure

Hey, I'm having an issue with my 2014 Peugeot 807 diesel. The air conditioning has completely stopped working. I'm getting an error code, the AC isn't cooling, it won't switch on, and the warning light is on. From what I've read, it sounds like the air conditioning control unit might be defective. Has anyone else experienced this?

Greetings. I had a comparable situation with my Peugeot 807. The air conditioning exhibited analogous symptoms. Was the refrigerant compressor operational at the time of failure?

Thanks for the reply! To be honest, I'm not entirely sure if the compressor was running right before it failed. Is there a way to check that without specialized equipment?

Affirmative, it is challenging to ascertain compressor functionality sans diagnostic instrumentation. Given the parallels in our automotive air conditioning predicaments, I would suggest a consultation with a certified technician at a reputable automotive repair establishment.

Thanks for the advice. I took it to the workshop, and it turns out the AC control unit was indeed defective, just as suspected. The repair cost me 980€, which is painful, but at least it's fixed now!
