As previous poster shows VW electrics can be a bit of a diagnostic nightmare.
So I'd begin by checking for battery V at the switch red/yellow wire.
I think??
For accuracy all kind of question have to be answered,
Like does it have memory seats?
Steering wheel controls..............
VW manuals ask a lot of questions before the correct diagram can be found!!!
