RE: vacuum pumps

[HAREST@allenbrook.iix.com]

Cruise control, like central locking, has it's own electric vacuum pump.

Electric lock vacuum pumps are usually enclosed in an insulation box, either
under the rear seat (5k) or the trunk (4k,coupe)
Cruise control pumps are usually located above or near the brake fluid
reservoirs on most Audi's

YMMV,  my memory always does ;-)
