Obviously am not a heavy brake user, my S3 has had the same pads and discs on for the last 70,000 miles! Too many motorway miles I guess.
Anyway, they do need replacing now, I got the following quotes for front and rear discs and pads (not interested in uprating brakes for obvious reasons):
Audi - £343 (includes 10% parts discount)
GSF - £198 (Brembo I think)
AVS/VWSpares - £201 (TRW)
Is there any reason not to just go for the GSF ones, are there any differences with the ones I would get from Audi?
Incidentally if anyone is interested my local Audi (maybe others) are doing a "deal" on full discs/pad brake replacements at the moment of £249 for fronts and £249 for rears all incl. Not bad for Audi maybe but still a bit steep if you can DIY...
