If you have GSF or ECP within your intended travel area, then at least ECP sell Pagid or maybe even Textar pads and discs, I've always found Pagid to be okay despite how, it has been said, ECP manipulate that brand's offerings by selling only a "shortened" range. I'd always aim to check the Pagid/Textar official website for their kit references and make sure that ECP is handing over their(Pagid/Txtar) listed kits for your car - otherwise aim to get another brand you recognise, sometimes it is very easy to get the exact correct parts aftermarket, sometimes it can be slightly trickier.
CCP otherwise known as Coverdale Car Parts, are worth contacting for genuine VW Group parts, I've used them many times, but always make sure that you know what your local VW Group dealership is asking for service parts - just in case you end up paying more from shopping elsewhere.
