Peugeot 208 AC Fault

My 2018 Peugeot 208 diesel is throwing a tantrum. Mileage is 139883 km. The AC compressor seems to have given up. I'm getting an error code, the air con is blowing warm, and the system refuses to engage. The AC warning light is on. From what I've gathered, the AC control unit might be the culprit. Anyone seen this before?

A 2018 Peugeot 208 diesel is experiencing issues with the AC system, including an error code, warm air, and a non-engaging system, with the AC warning light on. The suspected cause is a faulty AC control unit. After checking the refrigerant level and confirming it was not the issue, the owner took the car to a workshop where the defective AC control unit was replaced, resolving the problem.

Did this summary help you solve your problem?

Sounds familiar. Had a similar drama with my old BMW 3 Series. Same symptoms – error code, no cold air, system refusing to kick in. In my case it was also related to AC compressor issues, and the diagnosis pointed to the AC control unit. Before diving in too deep, have you checked the refrigerant level?

Cheers for the reply. Yeah, refrigerant level was the first thing I checked. Seems to be fine. So, if it was the AC control unit in your BMW, what was the eventual fix and how much did it set you back?

Right, refrigerant checked. In my case it was the control unit. Ended up replacing the thing. BMW wanted silly money. A reputable independent charged me a smaller fortune. Given your symptoms and the potential cause, I'd suggest getting it checked at a decent workshop. They can properly diagnose and confirm the control unit before you start spending money.

Thanks for confirming my suspicions. Took it to the workshop, and you were spot on. The AC control unit was indeed defective. Repair, including parts and labor, came to 980€. Ouch. At least I have cold air again.
