Audi Quattro : all are 3.89 (35:9)

WF - 07/80 to 07/83 (rotary diff lock on top of the housing)

ADV - 05/84 to 07/84 (Sport Quattro diff : 859 500 040B)

ALZ - 08/87 to 07/89 (lever diff lock that looks the same as the 5000/200)

However, there is no info for the diff between WF and ALZ. Maybe just a date
error ?

I CANNOT find this info anywhere. I used to know it too. Can someone tell me
what the 2-lette differential codes are for the 1984 4000Q, the US UrQ, and
the 1985-1984 4000Q? Thanks so much.
