shared parts w/ VW

need to use my $500, and trying to make a list of parts the A3 tdi shares with the dub 2.0 tdi's... anyone know of a good way to cross reference?
i know oil, oil filters, dsg fluid/filter - but surely there's more.

Brakes, suspension, I know wheel bearings(hubs) because I had to pick one up ASAP and VW dealer was the only place around who stocked it
