    Here you go:

    So if Audi have actually managed to be consistent from one end to the other then:
    AF-R = Grey
    AF-L = White
    S-GND = Black
    UB+ = Brown
    ACC Switched live = Red
    CLOCK = Blue
    DO Data Out = Yellow
    DI Data In = Purple

    Data In and Data Out (Yellow and purple) may be round the other way as its not clear which is in and which is out.

    Easier just to run the new cable otherwise you do need to buy a proper pin extraction tool
