which diverter valve makes the air purge noise. I was thinking of getting the EVO Billet DV and i think that makes the air purge noise. I'm new to the audi scene so bare with me. Thanks.

I think you'll find there all very similar.

Well i'm sure they are but don't some make purges and others don't? I've read that BOV aren't for our cars really so I want to go with a diverter valve.

diverter valves aren't gonna make a "purge" noise. if you want some noise, the recommended route is to get some kind of intake system and any metal dv (baileys, forge, etc).

but if you want a bov sound, you'll probably be disappointed to hear there are no solid options

they'll all make a sound depending on how much boost you're running and the type of filter setup..

GFB makes a hybrid. It recirculates 50% and releases 50%. you still get a noise and not get a CEL. I run a baileys. Its working great so far.

actually all you need to get an air purge noise is an intake, with the stock dv it still makes the whooosh sound

I have found that the EVO with an air intake sounds the best.

did a search. didn't get my question answered. I just got my car 3.5 months ago so i pretty much know nothing about these cars, but i'm learning. I saw a video with the jetta 1.8T that had the evo dv but wasn't sure if it made the noise cause of something different so i just wanted to make sure before i order a new one. But now i have a few different options to look into.

i agree.

audimus ed is running the Evo Dv with an HKS intake and you can hear the "woosh". haha.

i purchased one from Group 5, but havent installed it yet. ill let you know how it goes.

its not the prettiest one around but i dont want to spend over 200 just for an intake. it does some with a heat shield but like the others it's junk, so I'm just going to fabricate my own. a couple guys i know are running this intake on their audi's and seem to be happy with it.

Because of the design of the evo bpv, it gives off a higher pitch sound then the other flat piston type bpv's. This is because the evo piston that has a dimp on the bottom with round sides. So when the piston lifts the air rushes in and gives a slight whistle sound.

Now if you want a even louder sound you can go with a hybrid bpv, when set at full the bpv returns half the air and releases the other half to the atmos. Just be prepared because this setup will cause the car to run rich just after the bpv releases the air every time.

Pretty old thread, but ill try anyways.. So I have 01 a4 with unitronic chip st2, front mount, testpipe, ebay metal dv similar to 007 and knn cone filter. I am not happy with my dv noise witch is very quiet any one know why that could be? I tried all the different springs the dv came with and its still pretty quiet. I know dv aren't as loud as a bov but on my 99 a4v I just had the same cone filter, rest was all stock and it was way louder.

Carbonio Cold air intake + Forge Type RS DV/bov would be a really loud setup.
