Zoe AC Undervoltage

It's certainly plausible that undervoltage could cause the A/C compressor to stop. Have you checked the pressure sensor and refrigerant level? A leak could trigger such a fault. Also, has the AC relay been tested?

Thanks for the quick reply. I haven't checked the pressure sensor, refrigerant level, or AC relay. Where is the pressure sensor located, and is it easy to test the relay switch? I'm not a mechanic, but I can follow instructions.

Diagnosing undervoltage and A/C systems often requires specialized equipment. Given the potential complexity and the stored error, I strongly recommend consulting a qualified workshop. You could damage the A/C system further if you're inexperienced.

Thanks for the advice. I took it to a workshop as you suggested. There was undervoltage, and they found a faulty connection. Repair cost 240€, and now the A/C is working like new.
