If you mean type 85 quattro's then yes. There have been 3 evolutions IIRC:
1. Two pull buttons to engage center and rear diff in the first urq and 80 quattro
2. One turn button to engage center diff on stage 1 and both diffs at stage 2 in later urq and coupe and 90 quattro
3. Push button to engage rear diff like in the S2 on special edition and 20V urq.
