I had a 1990 coupe quattro 20V for nearly six years, A/C as distinct from full 
climate control, and I could always feel on the throttle when the A/C was on. 
It was intermittent, as you say, but quite frequent, and was as if there had 
been a momentary stop in the fuel supply.  Could be unnerving until one got 
used to it and made allowances.  I believe it was a bug which one just had to 
live with.

FWIW, I have now had an A4 quattro with proper climate control for ten months 
and 10,000 miles and I have never experienced the problem.  Our friends in 
Germany must have sorted the problem.
