Did my fronts at 105k and they still had some pad left. Might have been able to go another 3 to 6 months before the light would have come on. Doing the rears hopefully this weekend (115k miles now).

 

106,000 miles and still the original rears. My fronts are still good since the change at 74,000 miles. The only issue I'm having is in cold weather, one of the front calipers is sticking slightly. Couple wacks of the peddle, and it frees up. Took it in for the problem, but by the time I'm at the dealer, it won't do it for them. Story of my life with any car I've owned.

 

Be carefull with that!! I had that happen and then one time it stuck on and wouldnt come off, couldnt even notice when driving, needless to say the caliper was screwed and the disc was literally cherry red no joke!! Took it in and the rotor was still good but $400 for one caliper, although I normally do most of the work on my audi (done timing belt etc..)
