DS5 Driver Seat Heater Failure

Hello! I had the exact same problem with my DS5! I looked into the wiring and connections beneath the seat, but I couldn't solve it. Did you already perform some voltage measurement to exclude a power supply problem?

Thanks! No, I haven't checked the voltage yet. Where did you measure? Was the error code the same?

Yes, the error code was identical. I'd suggest measuring directly at the heating mat connector under the seat. In my case, everything looked fine electrically, pointing to a defective heating element within the seat. I strongly recommend visiting a workshop.

OK, thanks. I went to the workshop. They replaced the seat heating mat, and that fixed it. Cost me 390€. Bit annoying, but at least it's sorted. Appreciate the help!
