What mileage would you expect to get out of brake disks?

You've not worn out the discs that you got through the deal you organized have you nick?

From my experience its 2 sets of pads, about 40-50k.

Exactly the same for me.

I have 75k on mine and they are 60% or so worn now
I recently mic'ed them, at 70k or so

no cracks at the holes
I change pads every 30k or so, on the 3rd or 4th set

My experience is slightly different, I have averaged about 20k per set of discs and am on my third set of fronts at 53k. The discs have always gone long before the pads have though I am still on my original discs and pads on the rear.

I do quite a bit of urban drving which is all I can put the shorter life down to based on the mileage everyone else seems to get.

Dude there's something wrong with your driving / the car if you pads out live your discs! Don't kid yourself its the urban driving either, I used to drive mine in central London everyday when I still lived in London so rarely saw an open road and I am heavy footed.

I thought it was good practice to replace the pads when you change the disks?

It is and I changed the front pads each time the dics where changed. FWIW, the pads generally had a third left in them when the discs where changed.

It is, but it is not normal to wear out a set of disks by using 2 thirds of a set of pads, unless you use metal files for pads!
Normally you'd get a through a couple of sets of pads before you need to change the disks.

What made you think that the disks needed changing after just 2 thirds of a pads useage? Do you keep warping them or are you wearing them down? I find it hard if not impossible to believe that you can wear a disk down with less than one set of pads. Did you measure the disk thickness?
Are you using standard disks? and what pads?

Discs/pads all OE no warping. Audi advised change required due to wear which I usually ignore for 6/9 months by which time there is a huge lip on the outside of the discs and they look like the have been monstered on trackdays even though I don't track the car. Last worn set had visible dash-lined 'spokes' from the centre to outer part of the discs that kind of looked like lines of little cracks but where not.

I'd be tempted to get a 2nd opinion next time or get yourself some calipers (the measuring type not the braking type) and meausre the thickness yourself.

if you ignore for 6/9 months and still not get through 2/3 of a set of pads then I can only assume you must do very low milage. How old are the disks when they recommend you change them? Perhaps it is ibecause they have corroded / perished rather than worn.

Discs where 2.5 years at the last change, to be fair they looked fooked.

Audi discs are renowned for being made of cheese,one set of pads will easily do one set of discs.Some have done discs in 15k.
