Citroen DS5 AC Failure

My 2015 Citroen DS5 with a gasoline engine has an error message, no cooling, and the AC won't activate. A warning light is on. Could this be a defective AC control unit? Mileage is 41741 km. Has anyone else seen this?

I had something similar happen with my DS5. AC stopped working and threw some codes. Have you checked the AC pressure switch?

I haven't checked the AC pressure switch. What were the specific codes you encountered, and what did the troubleshooting process entail?

I don't remember the exact codes, but it was related to the AC system. I messed with it for a bit, but eventually, I just took it to a workshop. Turned out the compressor was shot.

Took my DS5 to a workshop, and they confirmed the AC control unit was defective. The refrigerant compressor was replaced. Total repair cost was 980€ Thanks for pointing me in the right direction.
