Introducing the new DV+ for late-model VAG and

Euro applications!

GFB’s DV+ solution couldn’t be simpler - keep what works and replace what doesn’t.

Worldwide PCT Patents and Design Patent Pending

  • Retains the factory solenoid coil for seamless integration
  • Replaces plastic valve parts with metal for reliability and strength on chipped engines
  • Direct-fit replacement with GFB’s TMS benefits
  • Exclusive “pilot-actuated” valve mechanism for rapid response at high boost

GFB expands the DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles.

The solenoid coil itself from the factory-fitted valve is great (the ECU opens it faster than any pneumatic valve so why replace it?), but the weak point however is the valve mechanism itself. So GFB’s DV+ solves this problem by replacing just the valve parts with an anodised billet aluminium housing fitted with a brass piston machined to exacting tolerances.

The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Read all about the DV+ story on the next page.

feature-2

Other manufacturers’ products involve replacing the entire system with a traditional pneumatic valve, requiring long vacuum hose runs, additional parts for tapping into the intake manifold vacuum, plus either a different solenoid valve to actuate the pneumatic valve or a ballast resistor to plug into the OE wiring loom. All these additional items result in a product that is slower, less responsive, more expensive and takes much longer to install.

GFB’s DV+ solution on the other hand is more responsive, less expensive, easier to install, and doesn’t cause compressor surge/turbo flutter. Oh, and it doesn’t require different springs or frequent re-builds.

The DV+ story: Better performance - more reliable

Exploded view labels snagit

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

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 their shortcomings.

feature-4

Common OE Problem #1
The diaphragm types are commonly known to rupture, especially when boost and temperature are increased as a result of chip tuning.

feature-5

Common OE Problem #2
The plastic piston-type leaks far more than most people realise (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 are strong enough to open and close the valve reliably at 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 though, whilst 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 the factory valve problems with a very simple and elegant solution. Keeping the factory solenoid retains all the benefits of the stock system, and replacing the valve parts with indestructable metal components ensures strength and reliability no matter how much boost you run.

That's not all. Rather than using the solenoid to directly actuate the valve, we’ve introduced a unique “pilot-actuation” system. This means the solenoid controls the air pressure that is used 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 ever 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 simply opens and shuts, it cannot partially open if boost pressure is low), resulting in better throttle response.

Unnecessary replacement kits are a compromise, not a solution

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

Nicholas

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 :)

Chris

I recently upgraded the OEM Rev. "D" diverter valve of my 2009 MKV GTI with a GFB DV+ kit. The car has a APR Stage 3+ turbo upgrade and the DV+ fit without issues and is performing flawlessly. Even though the second spring isn't required on cars with a DSG transmission like mine, I elected to use it. Throttle responsiveness is definitely improved, as is upshifting (not the gear selection but the power delivery). I haven't been able to detect any new noises.

Having used GFB products on previous cars and having nothing but positive feedback, when I saw that GFB were making a unit for the Euro VW/Audi range I was interested. I like how the DV+ replaces the known "weak links" in the stock DV with upgraded parts, yet still retains the factory electronically controlled solenoid. Beautifully made and fits perfectly, installation on a Golf R takes only 10-15mins. Having had the DV+ fitted for a few weeks now, it’s holding 26psi or so perfectly and the boost appears to be more consistent than with the stock DV. It’s nice to have an Aussie made product on the car too.

Just some feedback on the valve. It does spool the turbo more quickly and holds a bit more boost at the red line, somewhere between 30 and 50 mb. A run through the gear box produced some good results, in that after a Dsg shift, the boost jumps up so quickly and higher that I had to pull 2 degrees of timing in the shift area to prevent collapse of the timing curve. There seems to be a strong response off partial throttle to full throttle, more grunt so to speak, but exactly how much is difficult to quantify. In general it's operation appears much quieter, more rapid and direct. All been said and done, it's easy to install, looks good, and performs as good as you claim. I'm happy with it and will highly recommend it to anyone looking for an after market DV. Golf 6 R Dsg, Stage 2+, water meth, 287kw 542 Nm Sae on the crank, custom tune.

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

Stef

The DV+ is fantastic! The placement of the DV in my A4 made it a bit inconvenient to replace, but it was definitely worth the work. The turbo spools up much faster, and it retains boost much better than the old one (especially in that the old one just dumped all of the pressure after lifting off the gas pedal). The ride, overall, is a lot less jerky (from an already smooth ride) and it basically drives like a V6 now. Thanks a bunch to GFB. You guys are phenomenal. I will surely be looking into the G-Force II for my next mod.

Dan

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.

Jay

Would I suggest this product to someone, ABSOLUTELY. This thing kicks ass. My car now peaks around 16-17psi and holds strong at 15psi throughout the entire powerband. I have noticed the turbo lag became even more minimal and it also seems to have increased the throttle response. I did not get the pigeon sound that some people talk about. Another thing it did that I love it even more for is, it got rid of the whining my car would make when really getting on it. The car would scream like there is no tomorrow. Well, that is finally gone as well. Overall the quality of the product is incredible. It's clearly built to last and with stand any amount of boost pressure you try to throw its way. For about $140 you really can improve your cars performance.

Gavin

I'm running a stage 2 tune and had issues with boost loss. During moderate acceleration and while boost built up, gear changes during this time would result in a loss of boost. This issue has now been resolved with the application of the DV+! Not only did it fix the boost leak, but now has a noticeable improvement in throttle response! The guys from GFB, gave great customer service and advice to help me with the application and resolve my issue. Quality product and very happy with results! Thanks again!

Toby

Well worth it! The boost comes in earlier and stronger and it holds it all the way up. It's a very noticeable improvement.

Mark

I was put onto the GFB DV by a friend in the Dominican Republic of all places. Installation for the Golf R takes all of 10 minutes for the mechanically minded given you have direct access in front of your intake manifold. You can instantly feel the response of the turbo spooling up faster. On a mid 10 second car you wouldn't think it would be possible but it is. For spirited street driving or track day work this is a big plus. The OEM DV is renowned for boost leak to some degree but not sure whether gains are to be made in the drag strip, well not in DSG form but suspect for a manual there would be. Time will tell though! I'm not too fazed as for everyday driving it was a worthwhile investment and to support a local manufacturer was a big plus. Packaged well, top notch machining, easy installation, great value and does what is says is should, what more could you ask for!

Jared

I had ran both the factory unit and the latest revision and still had leaking and a "hollow wooshing sound" as my kids described it at almost any boost level. The car was sluggish and mileage was down. The car has a B&B turbo back exhaust and CTS intake system. Installed the GFB unit in about 20 minutes (took longer to get the car in the air than to do the install). The result was immediate. No more whooshing sounds, car was back to its previous acceleration levels and what I expected after the installation of the other parts. Gas mileage was back up, and we were back to being happy with the cars performance, and thinking of a ECU tune after the PCV upgrade and an intake manifold cleanout/de-carb.

Glen

Installed DV+ in my Proton Preve CFE, the boost can hold longer at higher rpm. Muted blow-off sound, it feel good during accelerate & its solved the boost leak issue as well. All thing done well when it paired with my Racechip, tmworks ignition harness. Totally different driving experience compare to stock.

Desmond

The DV+ is really impressive & works great. once installed, it can hold higher boost & can feel my car is moving faster than before. its also mute the BOV sound which i feel like driving an NA .

Desmond

This DV worked wonders in my 2.0 TSI Seat Leon FR, eliminated most of the lag found at low RPM's (running an APR stage II+ remap) and gave me full boost at a wider RPM range, I totally recommend it! Do not waste your money on those expensive valve kit "solutions", this DV is the s**t!
