You can buy a set at your FLAPS made by either Lisle or KD, I forget
which.  The set consists of 6mm, 8mm, & 10mm (maybe even 12mm) drivers
that you put into something like a 1/2" socket.  Or flag down a MATCO or
Snap-On truck, but a bit pricier.

Mine have always come off with the use of a 6-pt socket and a good
breaker bar.

I've never understood this myself.  VWs have a short flathead #3
phillips screw holding the rotor from spinning.  So simple, and you
don't have to dick around with lining up 3 sets of holes to bolt your
wheels up.  Though the screw can sometimes seize and the head strips
when trying to remove it to change rotors.  Then you're stuck drilling
out the screw.  Maybe that's why Audi doesn't do it, but doubt it.
Whenever I acquire a new VW the first thing I do is install a new screw
with anti-seize to make sure it doesn't become a problem down the road.
The only thing you can do on the Audis is use the alignment pin that's
in your tool bag in the trunk.  But that's plastic and won't last long.
Find yourself an aluminum one from a Mercedes ML or S-Class (14mm
threads).
