VW/Audi Performace Parts: GFB DV+ Diverter Valve with TMS Advantage for VW / Audi (T9351)


Product Features & Benefits

  • Sharper throttle response, lightning-fast valve actuation and the ability to hold as much boost as you can throw it!
  • 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 Advantage (improved throttle response and boost holding)
  • Exclusive “pilot-actuated” valve mechanism for rapid response at high boost

GFB DV+ Diverter valve (part number T9351) is a direct replacement for the factory valve on late model VAG and Euro applications that works with stock hardware, improves performance and reliability.

Keep what works and replace what doesnt...

The OE solenoid itself is great- the ECU opens it faster than any pneumatic valve so why replace it? The only valve on the market to solve the problem without flutter, excessive cabling and extra parts, installed in half the time at more than half the price. GFB’s DV+ range is designed as a direct bolt-on replacement solution for problematic factory recirculating diverter valves, eliminating failure issues from high temperature and boost pressure

GFB’s DV+ replaces just the valve parts with an anodised billet aluminium housing fitted with a brass piston machined to exacting tolerances.  GFB’s DV+ solution is more responsive, less expensive, easier to install, and doesn’t cause compressor surge/turbo flutter. It also doesn’t require different springs or frequent re-builds.

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.jpg 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.jpg 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.

    This upgrade allows you to take full advantage of the boost your turbocharger produces during heavy acceleration. Dramatically reduces the losses experienced at high rpms on the stock DV

    I own a 2010 Audi A5 2.0T 6spd with stage II APR. The car functioned well but there was something missing in the drivability. The shifts were fickle and mostly notchy. Pulling from Low gear rpm at Low speed was lagging. I called Etektuning with the intention of buying the Okada plasma coil hoping that it will smooth out the performance. I asked the opinion of the representative of Etektuning and he recommended the GPR DV+, and man, was he spot on. The shifts miraculously became smooth and the car never felt as response and great at Low speed. I did not get the name of the Etektuning rep. but thank u so much. It was the best advice I ever received for my car. This is customer service at its best, suggesting a part of couple of hundreds of $'s when I was willing to spend 5X the price. That's why I will book mark etektuning to be my performance part of choice from now on.

    The dv+ is awesome. My stock dv was leaking at peak boost (loud whistle) and popping this bad boy in eliminated that. Not only that. It's a little bit louder when venting than stock. Seems to hold boost better while shifting and seems to build boost quicker when you get on it, say, at freeway speeds.

    Also, etektuning was awesome to order from. Super prompt and fast shipping.
