Mine are the same at 8,000 miles.
Happened to take it into Audi recently for a quick fix on some plastic trim and, as part of the free health check, they claimed the pads are something like 30% worn!
Couldn't believe it after my 8V pads were only 50% work after 27,000 miles and were subjected to much firmer braking.
I seem to have managed to get rid of the squealing for the most part through quite significant and thorough cleaning of the wheels, discs and pads when washing the car. I have always been meticulous with cleaning and washing anyway, but have found I really have to spend a lot of time on the discs and pads for the 8Y
