    Since I've been on ASN I,ve seen a few threads asking want size brake discs I have as standed so I,ve desided to put together the list I have from my Audi repair manual

    Your car will have 2 codes within it's build spec list that form part of the vehicals spec plate/sticker which can be found in the service book or under the mats in the boot.Heres a photo of mine. CODES 002.jpg

    The codes you need are on the second line of box 5 so mine are 1KD(rears) and 1ZE(fronts)

    So heres the list FRONTS 1ZA 1ZC 1ZM 1ZD 1LJ are 312mm
    1ZE 1ZP are 288mm
    1ZF are 280mm
    1ZK 1LK 345mm
    1LG are 370mm(RS3)

    REARS front wheel drive 1KD are 255mm
    1KE 1KF are 260mm
    1KQ are 255mm
    1KU are 286mm
    1KZ 1KJ are 286mm

    4 wheel drive 1KF are 260mm
    1KJ 1KU are 286mm
    1KW 2EA are 310mm
    (RS3 312mm)

    Hope this helps as you can use these codes when ordering new parts and will save you having to remove the discs first in order to find you size first.
    These code will also tell you the type of brake caliper/piston size/brake disc max and min thickness and pad thickness and wear limits.

    Sorry to dig this up.

    I have 1KS ### 1ZA listed on mine

    So thats 312mm for the fronts, but the rears arent listed. MTEc replied
    "there are 3 sizes of rear - 260mm, 282mm and 286mm" for my car

    I have a 2011 A3 2.0tdi Quattro, Cheers

    I'm having the same issue...is it possible to fit 288 if you have 255mm without
    upgrading components?
