  • Audi V8 rear diff: AXZ vs. AFV

    Anyone know the difference between these two diffs?

    P/N

    AFV: 017 525 021H

    AXZ: 017 525 021Q

    A different letter usually represents a change - anyone know what it indicates in this case? Any idea if the AXZ is 'better'?

    diffcode

    why the difference between them i can't tell you, the Q verson are for the autotranny ,i think....i f you look at the std 4,111 diffs there are LOTS of different diffcodes also,but the same parts inside

      So it doesn't really mean that the 'Q' is better or tougher or it makes me (even) more popular with the girls...
