Skoda Superb Mirror Heating Problem

I had a similar issue with my Audi a while back. Mirror heating stopped working, and it turned out to be a broken wire inside the car mirror itself. Did you check the car mirror heater element for continuity? Have you had any other car electronics problems?

Continuity? How exactly does one check that without a complete mirror replacement?

Yes, checking continuity involves using a multimeter to see if there's a continuous electrical path through the heater element inside the car mirror. If there's no continuity, the heater element is likely faulty. Given the error code and your suspicion of a connection issue, the workshop's diagnosis seems reasonable. Maybe best to let them sort the mirror replacement.

Thanks for the info. I took it to the workshop, and they confirmed it was indeed a faulty connection in the car mirror. They repaired it for 95€, just like they estimated. All good now.
