It would be very unusual for basic parts such as hubs and bearings to differ between cars in the model line up. VW are particularly noted for using common parts as widely as possible not just on different models but also their 4 brands VW Audi.Seat and Skoda. no prizes for guessing that the same part will likely be most expensive from Audi and cheapest from Skoda
I had a quick browse on the Euro Car Parts site and all the hub kits listed were common between the 1.6 Petrol and 2.0GT TDI
