I can hopefully give you a little bit of help from my experience...
I'm running 235/35/19 on a 19x8.5 rim with an offset of 48. Admittedly I'm lowered on Eibach Sportline springs but that shouldn't matter for the info for yourself.
The results of this are:-
1. I had some rubbing on the wheelarch screw (just inside the top of the wheelarch) if I hit larger bumps that compressed the suspension a decent amount. Easy fix is to remove the screw and pop the liner above the tab that it used to screw into - you may also have issues with this as whilst you are not lowered, the tyres will be not only wider than mine, but taller in the arch too.
2. I've had some rubbing of the inner shoulder of the tyre rubbing on the inner wheelarch at the front on full lock. You will definitely have the same rubbing as I do (but worse) due to your tyres being both wider and taller.
I would say that the wheels would definitely fit (check the centre bore is the same, some audi centre bores are larger than VW ones even with the same PCD of 5 x 112.
I'd also say the tyres would be better downsized to 225/40 R 18 for a rub free setup.
