Mini Cooper Electric AC Failure

Sounds like my experience last year. Any weird AC noise before it went out? Check the pressure switch too. Could be a refrigerant leak if you hear hissing.

Regarding the AC noise, can you elaborate? What type of noise, and when did you notice it relative to the failure?

It was a high-pitched whine, almost like a dentist's drill, noticeable especially at low blower motor speeds. Eventually, the temperature control stopped responding. I'd get it checked asap. Likely needs a new valve.

Acknowledged. Your input steered me towards the likely culprit. It was indeed a faulty valve. Final repair including parts and labor came to 1000€. I appreciate the insights.
