Megane Hybrid AC not cooling

I had a similar problem with my 2018 Opel Insignia. AC stopped abruptly. A faulty AC relay was the culprit, easy to replace. But given your Megane is newer and a hybrid, the problem might be more complex. Any unusual noises from the AC compressor area before it stopped?

No unusual noises. Given it's a hybrid, could the electric motor influence the AC system? Or could the AC relay still be the cause?

It was the AC relay for me, but since your car is a hybrid, it might be different. I suggest a workshop visit. I've heard individual valves in the AC system can have defects.

Thanks for your help. I'll schedule an appointment to check the valves and diagnose the AC system. Estimated repair costs are around 1000€.
