It regulates the car dumping the air through the dump valve. If you have it you will see a resevoir ontop of your number 4 coil pack. The bypass removes it from the car so that it dumps the charged air as soon as you lift off the throttle. Have a look in the mk4 maintenance section and there is a right up on it. I used 4mm vacuum hose. 2 meters of it to do the bypass. I don know what the benefits are but it dumps charged air better  :grin:

mine was on his previous post and it'll be "boost leak! someone help!" or "where is the breather pipes?" with possible modding questions for catch cans to follow  :whistle:  :wink:

Lol yeah and like ive said its what forums r for. At the end of the day iv just got the car, i dont know much about um and the car has a few problems.
Plus the car already has coilovers  :wink:
If u aint got anything constructive to say then dont bother. If it wasnt for this forum id still have a blocked pick up pipe and oossibly  a seized engine. When my golfs got no problems and is how i want it ill stop writing so much. U dont have to click on my posts, u choose to.
