Here's a shot in the dark... early Scirocco's (at least up to my old '79 Mk 
1) had a mechanical brake pad wear indicator; a ridge cast into the rotor 
inside the main pad surface. When the pad wears down far enough, a shelf on 
the pad contacts the ridge every revolution. It creates a "thumping" or 
"thunking" sound, which can easily be heard through the floor pan/fender. 
You'd probably also feel a slight "wobble" in the steering wheel.
    And obviously it'll be consistent with road speed.
    Easy to check, just pull the wheel and see if there's a ridge on the 
brake rotor, I seem to remember it's about 2" long or so; if it's there and 
it's shiny check your brake pads.
