Hi all,

I've not posted before so forgive me if this is in the wrong place.

I have an S3 5 door DSG 2010 in excellent condition.

Now the weather has changed I keep getting ice forming on the internal side of the windscreen... a right pain to clear in the mornings. I've checked for water leaks, nothing is wet internally in the car, the boot is empty and no leaks. Further to this there's no coolant leak.

So totally dumb founded. I've used AC in the mornings to clear the droplets once melted and also wiped it all away with a towel.

Can anyone advise the next port of call? Even if I close all the vents at night it still forms across the whole of the windscreen.

Thanks...
