Standards for miniumu rotor thickness appear to be ver dependent on your country... :-/
Here in portugal our 07/01 Q7 had its first rotor replace ment at 150,000 km - went through four sets of pads. Note that this was an Audi dealership and associated Audi shop.
None of this "must replace rotors and pads at the same time" crap.
None of this "oh noes! The rotors have worn by 2 mm - replace them noaw!".
I think both the pads/rotor and the 2mm wear limit is trumped up rubbish designed to screw over the uninformed by turning a 450 Euro pad replacement into a 1200 Euro pad + rotor replacement.
But that's just me.
