Window won't come up, so my partner has decided to take it all apart to find out why.. Turns out to be a very common fault. The clips!
But has it been done? The pillar-less doors for an A3 .. If so how hard is it? Looks lovely like this
TT's are non framed... door seals would be the issue... TT seals are designed to have the window tucked into them... dunno if you could butcher something to work but would need a bit more thought than that tbh... the frames locate and guide the glass... not seen inside a TT door but would imagine there is something that hekps support the glas better.. TT's also have a 'feature' that drops the glass down a smidge on opening a door so that when the door is shut it can tuck under the seal then rises again to stop water ingress....
IMHO if you want frameless doors I would just buy a TT as it has them by design... doing this on an A3 seems problematic at best...
<tuffty/>
My old coupe had frameless doors...
and the windows didn't move as you opend and closed the doors ....
my wife's Tigra however is the same and it's windows move down half an inch before you open the door and then back up as you close it
