everytime i'm boosting, and i shift/release the gas, i get the BOV sound. i thought audi used diverter valves. so im thinking "wtf? is this one noisey DV?"

so its either a loud DV or a quiet BOV? anyone have any answers?

You guys talking about the "coughing" noise the exhaust makes?! My bro said that after chipping it (I think) the noise goes away. But mine has that too. [a3]

MMMM I honestly doubt its the exhaust because the noise Im hearing comes from the front and is associated with the boost building up and letting off (sortof like a blowoff valve like meesh described)

i dont think its the exhaust either. comming from the front of the car, and only when i release the pedal after any boost. sounds like bov symptoms to me, but im just curious... i guess we'll never know!

Audi never uses BOVs and I doubt they'd start now. The DV on the A3 2.0T is very loud. I noticed it right away after I started driving it.

The sound is similar to a GTI 1.8T with an aftermarket intake.

Most likely it's due to the intake piping on the transverse 2.0T. I quite like it... leaves no mistake that it's a turbo :)

There are two noises, the intake woosh/dv noise and the cough/fart from the exhaust. Both are due to the design of the respective parts. Intake pressure and exhaust pressure.

It's weird, but even my VR6 makes a "bov style" air woosh from the intake, and it's NA.

Sounds a little liek a giant Turbo Diesel.... Pretty cool. Love the DSG "burp" on shifts!

i heard it at the audi dealership!!! me and my friend were there while my car was getting serviced we decided to check out the new a3s. one of the workers there had just washed it and was putting it back, we both heard it when he let off the gas. it sounded pretty loud for a stock car and we were both like WTF? we asked him to rev it again but he said he didnt want to get in trouble. my car makes a noise too but it is not that loud at all.
