    Dump valve flutter??

    Me and a mate of mine both have 1.8t's,they have both been remapped by the same place,both have split-r dv's,the difference being mine is a dbw quattro,his is a cable throttle front wheel drive,his dv makes a loud (ish) dump sound,where as mine seems to flutter???....is there a problem as i can't work out why there is such a big difference in the sound they make??

    it is slighty more bhp,your right there,but not alot more,and i keep getting told mine will have a ko3 by some people and a ko3s by others,because it dbw??,so if i have the same turbo and only 12-15bhp more,why the big difference in sound,don't get me wrong,i don't want mine loud,just worried incase sumats wrong!!

    not sure mate.i know the quattro has 180bhp and a ko3s turbo and the 2wd has 150bhp with a ko3 turbo.so the 2wd with re-map prob has 185bhp and the quattro prob around the 225bhp i think??..prob sounds different becuase of the psi...or maybe just a leaking pipe or hose etc mate.

    sounds like you might have to adjust the spring tension abit they may have set them both up the same, turn the adjuster disc on top the valve where the vacum hose joins clockwise 1 or 2 turns then try it, may need 1 more if still not right

    Have a look at my post from a couple of days ago: http://audi-sport.net/vb/showthread.php?t=62730

    The advice I was given was that the dv is knackered and may be the reason behind the slight surging I get. I've picked up a genuine one from the stealers today and will fit it on the weekend. I'll report back the findings then.

    it's all about the engine code in adraid matey.....

    give us the engine code on the front drivers side of the head and we can tell you what turbo is should have!
