    I got myself one as everyone else has one:blow: just wondered what is the point of a dump valve. To be honest the one i have dont dump just makes a little woosh noise in the glove box :)

    I think the reason most people buy a diverter valve on here is that the Bosch OEM often breaks as the quality isnt the best. In terms of noise youll never get a loud whooshing noise unless its broken! Best thing you can do for the noise is fit a Forge Split-R and an aftermarket panel filter.

    Dump valve / diverter valve prevents the turbo stalling when the throttle is closed.

    I just got an induction kit and it makes the standard one sound more prominent

    The same as a Forge 007p Diverter except you can adjust the amount of air thats recirculated and how much gets dumped out.

    Have had one on mine for a few months with no problems so far, as long as its adjusted properly it should work fine.

    According to your sig you already have a 007P? I had one of them on my old 1.8T Quattro and the difference in noise between the two isnt that great, so if its just noise youre after, I wouldnt bother forking out the extra pennies.
