Product Details

Description

Introducing the T9380, the latest addition to GFB's DV+ range of diverter valves, designed with precision to serve as a comprehensive replacement for the latest generation of Continental brand OEM diverter valves commonly found in late-model Volkswagen and Audi vehicles.

Unlike the earlier-generation diverter valves crafted by Pierburg, the modern Continental valves resist disassembly and integration into a DV+. Consequently, GFB has innovated the T9380, incorporating a discreet, low-profile integrated solenoid. This ingenious design ensures a hassle-free installation process, eliminating concerns about clearance issues when replacing the Continental diverter valve.

Enhanced Boost Holding:

Since the introduction of electronic OEM diverter valves in the mid-2000s, numerous revisions have aimed to address reliability concerns. While the latest generation of OEM diverter valves has improved in reliability, a performance trade-off persists due to their operational method and plastic construction.

During GFB's boost leak testing on the OEM diverter valve in a VW Mk8 Golf R, it was revealed that the leak was significantly more prominent than in earlier generations. This excessive leakage is attributed to the emerging trend of manufacturers mounting diverter valves remotely on plastic piping rather than directly on the turbocharger. A plastic valve mechanism closing onto a plastic seat resulted in the most significant OEM diverter valve leak observed, measuring at 28L/min at 1 Bar of boost. Even with the Viton face seal featured on all DV+ pistons, the uneven nature of the plastic OEM seat face prevented a reliable seal.

The T9380 effectively tackles this issue by incorporating an integral piston seat machined into its body. This innovative design guarantees a proper seal, even on uneven plastic OEM seats.

Sharper Throttle Response, Faster Boost Recovery After Brief Throttle Lift:

Factory electronic diverter valves operate binary – they are either fully open or closed. However, your throttle is not binary. When making subtle throttle adjustments, the factory diverter's binary operation leads to abrupt changes in power delivery, resulting in poor throttle response.

The DV+ boasts a patented "pilot actuation" system that allows the piston to open and close progressively. This unique feature smoothens power delivery during throttle modulation, ultimately enhancing throttle response.

Fit's the Below Motors:

MK8 - EA888 EVO4

B9 - 2.9T EA839 TFSI / EA839 3.0 TFSI

C8 - DLZA 3.0T / DKMB 2.9T

  • 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 :)

    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

    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

  • 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

    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.

    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!

    Works great

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

    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.

    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.

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

    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!

    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!
