hi everyone.<br>last night i noticed a strange sound coming from outside the cockpit right after i pulled my foot off the gas pedal. <br>i stopped and tried again. from a standing start, dtsc on, i gave it half throttle, got it up to around 4000-4500 revs and then suddenly let it off without touching the brakes or anything, and right after i let it off, i hear a loud and strange echoing wooooshh. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0"> <br>i suspected the turbo hoses but the car is still pulling as good as it was before. so i'm guessing it shouldn't be a boost leak, but i'm not sure. what do you think?......<br>

Re: (Bender)

really? <br>actually it started just yesterday. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0"> <br>and now, the more i listen to it, it sounds more like a "khoooshh" rather than a "whooshh" and it becomes louder and more obvious if i let off at around 3000 revs where the turbo is just kicking in - but can't really totally kick in because i'm suddenly letting it off just then... it sounds like a valve closing and air being forced or something. do you think it might be the dump valve ?

its definitely your recirc. valve. and it didn't start yesterday <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"><p>you just started HEARING it yesterday <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"><p><br>the intensity of the volume is completely dependent on how much boost you have built up by the time you release it.

I took my airbox off & swapped it for an aftermarket cone filter. it does the noise all that time now :0).<br>It used to do it with the stock airbox too, when the cold air inlet pipe had fallen off. it's alot worse when it's cold.
