Product Details

Description

The T9381 DV+ is a complete replacement diverter valve in a super compact design. The T9381 is shorter and more compact than the factory diverter, ensuring it will fit the tightest applications.

The original DV+ (T9351) has an increased overall height of 11mm, which in some cases can cause clearance issues, such as with the vehicles below:

  • 2013.5+ Jetta GLI
  • Any MQB platform with an aftermarket intake or IS38 turbo
  • Audi 4.0 TFSI from 2012-2017

The DV+w/Pierburg Valve allows for more clearance, especially on vehicles running aftermarket intakes or turbo inlets. It also makes the installation easier on Gen 3 non-MQB vehicles such as the 13.5+ Jetta & Beetle, where the diverter valve is difficult to reach.

The DV+ Story: Better Performance – More Reliable

Many late-model European cars use ECU-controlled solenoid-type diverter valves. This is a good concept because the valve can react quickly and only opens when needed.

However, there are some problems with these valves. There are typically two types of solenoid-actuated diverter valves found standard on VAG and European cars, both of which have shortcomings.

Common OE Problem #1
The diaphragm types are commonly known to rupture significantly when boost and temperature are increased due to chip tuning.

Common OE Problem #2
The plastic piston-type leaks far more than most people realize (by design, not from wear) and doesn't always close after a high-boost gear shift.

Additionally, in both cases, the solenoid on the OE diverter is directly connected to the valve mechanism, which is not ideal because neither it nor the return spring is strong enough to open and close the valve reliably at a high boost.

With problems like this, you can see why other aftermarket manufacturers assume the best solution is to replace the factory diverter entirely. Unfortunately, although their replacement kits might be stronger than the factory diverter, their slower response speed and lower flow do not justify the extra cost and complexity – more of a compromise than a solution.

GFB has taken a different approach to deliver a complete solution that solves existing problems and improves performance without compromise or a hefty price tag.

The DV+ addresses factory valve problems with a straightforward and elegant solution. Keeping the factory solenoid retains all the benefits of the stock system and replacing the valve parts with indestructible metal components ensures strength and reliability no matter how much boost you run.

That’s not all. Rather than using the solenoid to actuate the valve directly, we've introduced a unique? Pilot-actuation? System. This means the solenoid controls the air pressure to open and close the piston, so it doesn’t matter how much boost you push through it; the DV+ will open and close reliably without exceeding the solenoid's capability.

This feature also improves on the factory system by opening the valve progressively in response to boost pressure, so it only opens as much as required to get the job done (the factory valve opens and shuts, it cannot partially open if boost pressure is low), resulting in better throttle response.

Product Features

  • Sharper throttle response
  • Faster boost recovery after gearshift or brief throttle lift
  • Improved boost holding
  • Unrivaled longevity

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    Have had this product installed on my Stage 2+ Golf R for awhile now and love it, boost comes on harder and stays on without any leaks or spikes. This has basically fixed the leaking and boost issues my stock DV couldn't seem to cope with. Unit is nice and stealth & retains the OEM ECU operated control rather than a full mechanical unit like some other units out there, so therefore this unit reponds faster. Overall love the product, does what it is meant to for half the price of any other product out there. Good work GFB, one happy customer :)

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    This product is great!I had been searching for a BOV/DV upgrade for my Audi S3 for a little while and I stumbled across this. I am very pleased with the results.The results surprised me. There was an instant improvement. The turbo spools up quicker

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    Fitted the DV+ to my 600 ps Audi TTRS the other day.First impressions are very good,holding boost nicely and throttle response is sharp.Looks like a well made quality part and well worth the money.

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    I've had the DV+ on my car for quite a few miles now, with no problems at all. It's still holding boost great, throttle response is better than oem, and the car is running awesome. I've spent much more and gotten much less on mods before, so this was a good buy in my book

    Jeff
  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    The be all end all of DV's for the Audi, finally. I was sick of ripping the rubber diaphragm DV, and then got sick of the sluggish leaking performance from the revised "D" piston DV. There wasn't a happy medium until the DV+ came out. Ever since install, I've been extremely pleased and will back this product up 100%. It feels good to hold boost again, and have responsive throttle response when needed GFB, great work guys

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    So much better

    My GTI is so much more fun to drive with the DV+installed. The unwanted noise from the intake is gone, prior it would hiss and howl with all the air leaking by my stock dv now its sealed up. Throttle in is much faster and accurate, its smooth and quick. Shifts don't cause a loss in power anymore, they feel faster and stronger now. Couldn't be any happier with such a small modification.

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    Everything is true

    Better throttle response. Holds boost better at higher rpm. Hardly felt any boost lagg. Builds boost hella quicker. Sharper and louder bov sound with intake (awesome!). Def feel the difference between dv+ vs stock. Must have for mk7s.

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    This is a must buy! It almost eliminates boost lag! Throttle response is so much better! And you feel it through every shift. Especially dropping gears at a higher speed. 6th to 4th feels incredible!

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    This is a must buy. Easy install. Noticed a huge difference in throttle response. No turbo lag.

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    Works great

    Holds boost way better than the stock DV and helps hold boost at higher mph down shifts.

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    Awesome

    The go fast diverter vaulve was everything I expected with a tune it hold boost better than stock and make the throttle smoother and makes for a better driving experience

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    Thank you so much

    So the reason of ordering this,
    Is I installed Cobb CIA and Cobb tuning after install
    It would make an annoying noise (not the turbo noise) so looked online did my research and found out this would help me the noise,
    And YESSSS IT DID!!!
    now that annoying noise is gone and I can finally hear the beautiful turbo
    Thank you guys.

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    Excellent

    Honestly it work fantastic and I can tell how much faster boost builds and how it holds it a lot better. More than just the performance, I get peace of mind knowing I don't have to worry about that part later on due to excellent buildsmanship of the part. I have zero issues with the part so it gets 5 stars.

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    DV+ is awesome. It holds my boost at 12.5psi constant throughout all 6 gear shifts. Highly recommend.

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    Great delivery / Easy install

    Super fast delivery. I had one issue with the installation (my own doing) and something for others to note, when removing the OEM DV, make sure you have a good hold of it and its secure when you remove the last bolt. I had a couple of parts fall into the engine bay but luckily they were easily retrieved.

    Otherwise great product! working well so far. Great speedy delivery and thanks Modded Euros!

  • Review shared from Go Fast Bits DV+ Diverter Valve - T9351 (2.0T FSI & TSI Engines)

    I added this modification after the Stage 1 APR ECU upgrade vavle lift. The boots comes on quicker and holds longer from about 1500 rpms. I would definitely recommend added this to you Audi A4!

    Worth its weight in gold

    This thing is great awsome upgrade from the garbage ve sells its costomers must have for 1.8-2.0 platform it does everything it sez its nice to purchace a quality made product for once the only thing is the diverter is simple but getting to it and making the room takes some time but once ur done ur happy u took the time
