Exactly, and maybe check if a TX30 fits it and not the frequently used in VW Group cars, TX27 - finding that out prompted me to buy in 2 TX30 1/4 bits this week!
A "medium quality" set of taps and dies that I had to buy when I first needed to work on a VW Group product, ie 2002 VW Polo back in January 2006, was one of the best buys I've ever made! Life would have been much easier if I had bought that before than, but I didn't reckon that VW Group fastenings on a 2002 VW Polo were just CZ carp!
