Hi,
I've got a late 2012 A6 Avant C7 3.0 TFSI which is imported from Japan.
The panoramic roof isn't working from the switch on the roof, neither the sunroof itself or the blind do anything from the switches. I've plugged VCDS in and run the basic settings to relearn, the blind is fine but the roof itself opened but not all the way then closed, then opened again, not all the way and then stopped. I've tried to hold the switch, run the process multiple times and nothing works, in the end I had to close it manually with an allen key.
I feel like there are 2 issues, the motor works but it seems to not be able to fully open the roof and it seems to struggle, I've tried to help by pushing the roof as it goes but it doesn't help. Looking at the mechanism there is some loose foam from the headlining around it so I suspect it has got into the mechanism and is jamming it. The other issue is I suspect the switch panel has failed, the interior light is intermittent and pushing on it makes it work again which suggests a loose connection?
Is there a way to see if the switch is working in VCDS? I've bought another interior light/switch panel but its not the same, it doesn't have the glasses holder but the switch looks the same so when that arrives I'll try it but would be good to see if the switch is working or not
Any tips for diagnosing or fixing?
