    A Diverter valve is fitted to the current VW/Audi turbo engines.
    When you close the throttle the boost is returned to the vacuum side of the turbo, keeping it spinning.

    A blow off valve or dump valve will vent this boost to atmosphere, creating a whoosh noise on gear change. These do not work very well on the current VW/Audi turbo engines
