Hello, I'm experiencing an issue with the mirror heating feature on my 2014 Cayenne v6 Platinum. When I scan for codes, I get code 0398 (Heated exterior mirror, electrical fault - electrical fault in circuit).
In the live data, whether in accessories mode or with the engine running and the vehicle parked, I get: mirror heating output: 0%, mirror heating: off, even when I press the defroster button. However, if the vehicle is running/driving the live data shows mirror heating output at 100% and mirror heating as “on” when I press the defroster button. When I switch it off, the heating output drops to 0% and mirror heating shows as “off,” so it seems to work while the vehicle is moving. But to be honest, I don’t feel any heat on the mirrors. The rear window defroster works without any issues.
Does anyone know what could be causing this issue?
