AMG GT AC Problems

Has anyone else experienced AC issues with their AMG GT? My 2022 AMG GT with a gasoline engine is having AC problems at 65696 km. The air conditioning just stopped cooling, and a warning light popped up on the speedometer. Plugged it in and it shows an error related to the refrigerant compressor. The AC system refuses to turn on now. Could this be a refrigerant leak or something else?

Sounds frustrating! Had something similar happen with my old Audi A4. The AC just quit. Did you check for any obvious signs of a refrigerant leak, like oily residue around the compressor or any of the lines? Is the compressor clutch engaging at all when you turn on the AC? Seems weird that a '22 car would already have AC unit issues.

I didn't notice any obvious leaks, but honestly, I'm not really sure what I'm looking for. How would I tell if the compressor clutch is engaging? Is that something I can even see?

Yeah, on the Audi, the oily residue was pretty clear around one of the fittings. As for the clutch, you should be able to see the front of the compressor. When you turn on the AC, the center part should engage and spin along with the pulley. If it's not doing that, then power isn't getting to the compressor. Best to have a workshop check the vehicle HVAC though. I ended up needing a new AC compressor.

Thanks for the insights! Sounds like I'm probably in for a trip to the workshop. Turns out the diagnosis pointed to a defective AC control unit, causing the compressor failure. Cost me 980€ to get it sorted, but at least the AC is blowing cold again.
