How does dealer know front rotors and brake pads need replacing if wheels never came off?
I had the 65k service yesterday
Audi dealer service shop then "advised" front rotors and brake pads need replacing plus rear pads.
Also stated my 3.2 TT has slotted rotors (it doesn't) that's why they are so expensive!!!!!

Can't comment on the slotted rotor part but >>
Pads can been normally checked through most aluminum rims (although not the best way to do it). Most places will recommend new rotors with new pads or if there is any visible wear. I'd try for a percentage left of the pads. Other than that it is pretty subjective.
On the whole I'd say that the dealer is fishing for work. Pop a wheel off and measure how thick the pad left is. Try to check all four front thickness because if one brake is dragging a bit then you can have uneven wear.

You can measure the brake rotos with the wheels on...>>
and observe the pad thickness as well....

1) Place caliper over rotor ensuring the outer wear ridge passes through the relief area in the caliper jaws.
2) Read the measurement in Millimeters
3) Compare measured thickness to the following:
Vented front rotors: New (25mm) replace at (23mm)
Vented rear rotors: New (22mm) replace at (20mm)
Solid rear rotors: New (9mm) replace at (7mm)
4) replace rotors as necessary<ul><li><a href="http://www.modshack.info/caliper.htm">http://www.modshack.info/caliper.htm</a</li></ul>
