I put one of these on my 8v a3 because my oem valve was leaking every now and then. After 2 weeks, I’m ready to put the defective oem one back in, it leaked less! The DV+ CONSTANTLY leaks. Has never sealed completely since day one. Sometimes it sticks all the way open, sometimes it feels like I’m tapping the brakes during a pull because it won’t stay sealed. Sometimes taking off from a stop it won’t seal at all just pshhhhhhhhh no boost until I let off then WOT. Lesson learned, get newest revision of OEM.
Did u try sending it back to the company and getting a replacement? The GFB's are backed by a lifetime guarantee and as with anything, the odd defective one may slip through the net, even if it's brand new. Shame to hear you've had a bad experience with it, as the week I had mine, I couldn't fault it at all. But there really is nothing wrong with the OEM versions either, so hopefully ur car is boosting now as it used to 🤞🏻 Cheers
I personal have this valve on my 1.8t along with throttle pipe and turbo outlet and intake. I can tell a huge difference from factory DV and this new one. I feel like it opens up just enough to where factory DV opens all the way. I have had it on for about 3 days and doing fine.
I have the T9351 and the leak was actually from the OEM piece, from the connector. I wonder if this all in one GFB DV has any leak issues from the connector
I'd like to think it wouldn't unless it was damaged/hit by another engine component. The build quality of this unit is 10/10, and should last a lifetime if looked after 👍🏻
Leaking from the connector is not uncommon on the OEM solenoid, but the T9351 does actually solve that issue. Let me explain - in factory configuration, the OEM solenoid is exposed directly to boost pressure via the transfer holes that balance pressure in the piston. The moulded plastic can develop a leak path that is often seen as oil dripping from the connector. The T9351 however isolates the solenoid coil body from boost pressure. This is because the pressure is contained behind the piston by the plunger. When the solenoid turns on, the plunger opens but importantly the path it opens flows more than the transfer hole in the piston. Therefore, the solenoid coil never sees boost pressure with a T9351 fitted. If you do see a leak from the connector during a pressure test with a T9351 fitted, chances are that's the result of the common pressure test applying pressure to the turbo intake. This method results in the diverter valve receiving pressure from both the inlet and outlet side. Pressurising the diverter outlet allows pressure to get to the solenoid coil via the relief passage running along the side of the T9351 cone. When driving the car on boost however, there is NEVER a situation where the diverter outlet passage achieves pressure, so even if the OEM solenoid is cracked and leaking, it won't actually leak boost when driving if a T9351 is fitted. In any case, the T9381 is immune from this issue for the same reason described above - there is no way the solenoid can ever receive pressure when driving.
Hey mate, so I've never had an error code or engine management since fitting it. Still performing perfectly 👌🏻 it doesn't change the turbo sound, you will hear more turbo noises by having a large intake fitted instead. The main reason to buy this is to hold higher boost levels compared to OEM ones. You might hear a few more noises on half throttle/letting off the throttle due to the design of this one adjusting it's position depending on what your foot is doing and the boost is doing.
They are listing a different version for your car. You can use the link below to view the option for your vehicle 👍🏻 www.gfbuk.com/products.by.make.cfm?makeid=176
Hey DSV 👋🏻 Yeah the GFB DV's do seem to give a more audible turbo flutter, but this is probably more noticeable on mine with the large induction kit. So I recommend if you haven't got an induction kit, try that 1st. As for fitment I'm not 100% sure if it will fit your car. The older version which I'll link below, has a full listing of what car it fits. There are some 1.4 Tsi engines listed, but not under a seat Leon. But maybe you'll know if your engine can be found in other manufacturers, the same as my engine is. Hope that helps a little www.akstuning.co.uk/shop/home/214-gfb-dv-t9351-tfsitsi-platform.html
I think it's only worth buying if you're planning on increasing power from the engine at some point or you are experiencing issues with your current diverter valve. Otherwise if your car is running perfectly just now, I would save your cash. Maybe put it towards a good induction kit.
I was unfortunate enough to get a gen 3 b north American passat. This will fit, which is why I will be ordering one, but I am currently running the gfb dv+ bov spacer on the stock dv housing. let's just say it didn't fit without some modification lol current mods are cts cai, cts 3" catless dp, cts charge piping and turbo muffler delete, full 3" exhaust, and a stage 2 tune.
It's exactly the same as the older version, just in a smaller form. It should hold more boost than the revision G OEM diverter valve, but the revision G is a very good diverter valve too for most applications. My full run through of this new GFB DV+ is in this video if you want to understand it all better 👍🏻 ua-cam.com/video/FwW4SQYYgHk/v-deo.htmlsi=doHDzmdKKqFcQg9E
The one I have currently was a custom request from a company called 'PP3D'. You can find them on their website or via Instagram. And email or DM to them with what you're looking for, plus a picture should get you on track to getting the one you want 👍🏻
This is the last stretch of the A9 which covers a fair amount of Scotland, starting from close to Glasgow, and finishing on the north Coast up here. If you search for a village called 'spittal' that's half a mile north on the road that I had the drone shots 😊👍🏻
If it flutters, is not good, factory one will always be better, even people running 600+hp are using the factory dv valve, no point on changing it, i exploded my is20 turbo using an aftermarket dv valve, never again.

Just saw this new valve and immediately had to find a video of it. You're the GOAT for being the first.
Thank you Austin, kind of you to say and hopefully the video was of some use for you 👍🏻
@NorthCoastWorkshop Absolutely. I've been looking at diverter valves for my wife's Tiguan, and I think I'll go with this one.
orderd one for my VW jetta gli and been on back order for the past 4 months and its finally shipping out cant wait to hear it in my car
Awesome, let me know how you get on with it 👍🏻
lmk how it went I know the diverter valves on the non-mob ea888 gen 3 are in a different location than in this video
Please let us know how it is bro

Great to hear you're pleased with it so far Brandon 👍🏻 it is a great bit of kit
Looks awesome mate 💪
Cheers Craig! 👍🏻
Aye can smell your grubby top all the way down in Aberdeen 🤣😂!
Cracking video Kev, loving the drone shots they are ace.
It's honking!!! 🤣🤣
Cheers mate, yeah I was pleased how the drone shots turned out. Was having to be careful not to fly it into the wind turbines 😬😎
Haha yeah I'm sure those big blades would come off the best in that fight.
That road looks sick mate 😍
Car or the scenery??😁
@@NorthCoastWorkshop is it fair to say that for the first time I can’t choose? 😬 😂
Please continue to make content bro.
Cheers Charles 😁👍🏻 I've loads more content planned, and as long as you guys show up, so will I 😎👌🏻

Ok
Hello, does it change the Turbo sound compares to the original DV or is it the same ?
Any error codes ?

Will this fit on Golf 6 1.4 tsi caxa?

Seems like it gives the flutter sound. Does this fit on a 1.4 TSI Leon 1p? I hope so i can order

I think the diverter valve + fits in my car. You think its the money worth? Car isn't tuned anyway.
I think it's only worth buying if you're planning on increasing power from the engine at some point or you are experiencing issues with your current diverter valve.
Otherwise if your car is running perfectly just now, I would save your cash. Maybe put it towards a good induction kit.

Sounds like a nice wee setup you have 💪🏻🔥
Let me know your thoughts once you fit this too 😊
Is this one better Rev 3
Which one's better
It's exactly the same as the older version, just in a smaller form. It should hold more boost than the revision G OEM diverter valve, but the revision G is a very good diverter valve too for most applications.
