Skoda Superb Hybrid Temperature Sensor Issue

Sounds similar to an issue I had with my Superb. The air conditioning cutting out is a telltale sign. Did you check the sensor calibration or look at the engine cooling system? I'd also suggest you inspect the heat exchanger for any visible damage.

Can you elaborate on your experience? Was the error message in the speedometer also present, and was the air conditioning control unit defective as well?

Yes, error message was identical. The air conditioning was completely disabled as a failsafe. From what you described, it's almost certainly the same issue. While you might try some DIY fixes, I'd recommend taking it to a workshop. Modern systems are complex.

Thank you for the confirmation. The workshop confirmed the defective temperature sensor heat exchanger. Repair cost was 980€.
