Hi,

I'm 100% certain that our S8 had heated windscreen fitted as an option from factory, the screen would demist in seconds when the blowers were switched on to windscreen setting. However, after a screen replacement and seeing the fitter playing with wires attaching to the screen, the wind screen no longer demists anywhere near as quick.

I've scanned the Hvac with VCDS and all of the flap motors are working correctly.

Where is the the heated screen control unit hidden on the car and the wiring which runs to the screen, does anyone know? I'd like to try and repair this function.

The windscreen was fitted a couple of years ago now and the car has been stood for 18 months whilst i'm in the process of recommissioning it for an MOT.

Just to add that the heated screen function had stopped working before the '8 was taken off the road.

Thanks.
