Hi there, can comfirm Axios's part numbers, check for 06 reg Quattro.
286x12mm discs - 1K0 615 601 M
Brake pads - 1K0 698 451 H if your vehicle has PR code 1KU
or 1K0 698 451 G if your vehicle has PR code 1KJ
Not too sure myself of the differences in the pads & don't know how much of a difference your PR code is going to be since you upgraded your discs & pads but that was the info i got off ETKA 7.
Hope this is of some help to you though.
Cheers
