Other versions of the VTA are designed for use on cars that do not have any kind of factory-fitted diverter valve. Vehicle manufacturers have deleted the troublesome solenoid type diverter valve from some of the newer models, but this leads to turbo compressor surge which can be taxing on the turbo in the long run. The VTA valves for these cars are designed to re-introduce the function of a diverter/blow-off valve to help protect the turbo in the long term and also provide a blow-off sound.

I had an audi dealer technician install it. statted receiving check engine lights. my car was shaking in idle. then would also shut off mid drive. I had it removed ,coes cleared and statted running as normal again. I tried returning it, and they told me "try adjusting it", "read the troubleshooting guide". what a joke of customer service. you'll find on youtube that hundreds of people had the same issue with the part.

had the "standard" DV+ on k04 mk6 GTI for years -- GREAT product!!!! moved on to a b8.5 allroad with e895 stage 1 -- and bought the "stack" VTA model this time -- took a while to get it mounted and operating correctly due to the location on the audi 2.0 TFSI (and large hands and fingers :p ) - but once it was dialed in .....WOW. Fantastic boost retention, spools feel "cleaner" and smoother with no surging , and the sound, THE SOUND !!!! ....for me, with the added boost from the e85 tune -- sounds like I'm running a true BOV underneath with a prominent audible "POOOOOOOOOOOSH" when shifting or letting off the fun pedal on a rip .... emailed and called GFB (yes, in AUS !) on a couple occasions to help with some of the little gremlins that were getting me on install , ... Morehad the "standard" DV+ on k04 mk6 GTI for years -- GREAT product!!!! moved on to a b8.5 allroad with e895 stage 1 -- and bought the "stack" VTA model this time -- took a while to get it mounted and operating correctly due to the location on the audi 2.0 TFSI (and large hands and fingers :p ) - but once it was dialed in .....WOW.

The quality of this item is spectacular, very easy to install, though I ran into an issue with clearance. Due to the height of the VTA when attached to the factory DV body, my turbo inlet pipe would not lock into place. While I was able to install it, the fit was way too snug and the turbo inlet pipe never locked into the appropriate place, I actually broke the arm on the inlet pipe trying to get it into place. I would recommend this for another car, but not for the MK7 GTI. I will say that ECS handled my return incredibly well, customer service was on point. Gonna try the Turbo Smart BOV instead.

Easy to Install and has a very nice aggressive sound! Definitely Recommend
Not working,VTA PISTON IS STUCK,i'm trying to repleace as warranty,This is my 2nd VTA,1st VTA 2006 GLI WORKS EXELLENT 5 stars,VTA doesnt compare with spacer adapter
Installed this on my 08 mk5 gti and it sounds really good and loud, would definitely recommend this blow off valve, install was really easy and they give you instructions on how to do it as well.
This was a night and day difference for my 2010 MK6. I'm sure I had a boost leak before from a damaged diverter valve, because the throttle response and boost retention is significantly better now than it was before paired with a new (latest revision dv). Plus it sounds fantastic. Simple install with basic hand tools and clear instructions. Couldn't be more satisfied!
It greatly improved the throttle response, not sure about the boost retention. I haven’t really noticed a difference there. The sound is actually less aggressive than it was before. Easy installation.
Ive always wanted the blow off valve sound and this product was the perfect aftermarket part. Put it on in under an hour with just floor jacks. Lets off the perfect sound when shifting. Thank you so much. Was so worth the purchase!
This direct form blow-off valve was a perfect fit for my MK5 GTI. Now the atmospheric sound is amazing and I love the intimidating sound it produces. So easy to install, just minutes later, we were rocking and rolling with a swish heard from several hundred feet. In love with this product!!!!
