Welcome to torquecars. Tell us about your car in the VW section we are getting quite a few VW owners signing up at the moment.

I've got an audi 1.8T which may be a similar engine to yours. The ECU will decide that pressure is lost in the system and adjust itself to try and compensate. The Audi has a closed loop system and seems to monitor the combustion process every step of the way! Some people have used used them and not noticed a problem but others have taken them off.

Heres a question: Do dump valves increase performance? Let the arguement begin.
