    turbo problems

    heres a brain teaser for everyone ive got ann audi s2 on a 95 plate everything is totally standard on it. The other day i noticed everytime i changed gear the turbo makes a weird noise like ive got a dump valve in the car i cant work out why its doing that. might be losing preasure from somewhere any ideas

    if its 'just' started making this 'pssst' dumping noise on gear changes, then it sounds like you have a hole in a hose to be honest... time to get your hands dirty.

        I have realised that the car is alot slower even though the turbo is cuttin in its weird its like its sounds like its sucking in air. similar to what a dump valve would sound like.

              I had the same symptoms, turned to be dump valve and a throttle body pipe. the standard s2 DV doesnt last long.
