Yes, this happened to me once - at traffic lights, was about to change in to gear and it just snapped, leaving the pedal moving freely and cars behind me having to go around, as I could not move the car
Pushed car to the side of the road and had to call for recovery, who fitted a temp clutch cable so I could get home, then I had a proper VW part fitted.
You could replace it yourself without too much hassle!
