    Hi guys,

    My brother has an S3 2.0tfsi. It is a standard car and has started to chatter when coming off the throttle instead of dumping air; sounds as if the DV is not operating and the air is being forced back through the turbo..not good!
    Is there any way to test the OEM dumpvalve on these cars? It looks as if it is electrically controlled rather than vacuum controlled as in the 1.8t engine.

    Any help would be much appreciated.

    Cheers.
    Dan

    remove the dv and check for tears. could also be a worn actuator maybe.

    Forge looks fairly easy to fit? The t-piece to tap into the vac pipe comes as part of the kit with the forge does it?
