Expedition seat heater malfunction

I had a similar issue with my old Audi A4. The seat heating didn't work and showed an error. In my case, the thermal sensor in the seat cushion was defective. Is the error message related to the seat heating circuit?

That's interesting! I didn't think about the thermal sensor. How can I confirm that's the problem? And yeah, the error code is specifically for the seat heating system.

In my situation, I wasn't able to confirm it myself. I suggest bringing it to a workshop. They should be able to pinpoint the issue using diagnostic tools and test the sensor's resistance. If you're lucky it's a simple fix but be prepared for the worst.

Thanks for the tip! I'll take it to a workshop. They found out that the seat heating mat was defective. Repair cost was 390€, but at least it's fixed.
