Thanks for the quick response. Where is the AC relay located, and how do I test the pressure sensor? I don't have much technical knowledge, so any guidance is appreciated.

I'm not an expert, but the relay should be in the main fuse box, usually marked with an A/C symbol. Testing the pressure sensor can be tricky and potentially dangerous without the right tools. Given the undervoltage error, it might be best to take it to a workshop for diagnosis. Better safe than sorry.

Understood. I appreciate your advice. I took the car to a workshop, and you were right. It was a faulty relay switch, likely triggered by an undervoltage condition. The total repair cost was 240€. Thanks again for your help!

I had a similar issue with my XC60's A/C. Have you checked the AC relay switch? It's a common cause. Also, check the pressure sensor; a faulty sensor can cause the compressor to shut off.
