Need some disc and pads soon car is a tdi 130 so what size do i have and can i upgrade discs in size if i get calipers etc,

i would think 288mm. If you want bigger you need to change the carriers and caliper mate

It will depend on your wheel size. If you've got the standard 16"s then you should be able to fit some 312mm discs by just changing the carriers. If you already have larger wheels then you're limited by them, and / or your bank balance

But ... why do you want them?

get some 312 discs and some vRS carriers mate, Im sure there will be some around.

iirc the pads are the same too

Thanks for info need new discs anyhow so thought ide go abit bigger.
