Are they much of an improvement over stock?

Worthy upgrade, holds boost much better than any oem version. A noticeable difference on my car !

Much better.. than a rev G? Any logging or solid proof you can post?

I know they're a better long term solution than the oem valves. I know tuned cars can eat oem valves within a year. I know they hold boost as well as a rev G. But much better?

I'm not knocking what you're saying, in fact I'm considering upgrading to a dv+ at some point. If you can tell me why they're that much better than oem it'd make my decision much easier!

They hold boost the same as a Rev G. It'll easily out last a Rev G  ( my last rev G split within a few months)

What it makes a huge difference with is drivability and throttle response. Transitioning between boost and vacuum is so much smoother and unlike the OE valve, this closes when the boost pressure has dissipated rather than being held open for far too long by the ecu/solenoid. Worthwhile upgrade and mine has already paid for itself in terms of durability.

I believe the price is a set/standard price from GFB so no group buy discount.

I had a rev G intact and noticed the throttle response after fitting this valve. It's worthwhile! :wink:

It will make more noise with an open cone filter. I have the OEM airbox and I can only hear it rarely with the a window open.

Running one of these on my s3 with a revo intake and can only hear a slight noise when lifting off on full throttle so isn't noisy at all  :happy2:

Like already said it sharpens throttle response and found on part throttle it feels more urgent and ready to go unlike the revG which sometimes could feel a little flat in the same situations

Definitely going to have to go ahead and buy one of these I think!

As my revision D diverter valve seems to be leaking already :ashamed:

Had a  stutter  under  acceleration and checked on the VCDS and got the "boost pressure not realised" (sorry, that's not exactly what it said but I can't quite remember the exact wording) code :doh:

Appreciate the feedback of this product!

Same boat, swapped G for D and had the low boost code.

Coincidentally it was the same day I tightened one of the hoses so I'm not ruling it out that I possibly tightened too much and ripped it.

Never really read into these. Can you fit them onto say a broken D/G valve? Running a G but thinking if that splits can I fit one of these to it broke

Yes.

You only use the solenoid off your REV G and remove the diaphragm part.

Although it's unlikely for the solenoid to fail, it can happen.

It's probably the DV :fighting:
I wish I'd done my research a bit better before shelling out €100 on the revision D. As I had a perfectly good revision G on the car :ashamed:

I thought the D was a solid upgrade from the G. It was only after I'd bought it and fitted it that I saw people's comments that the D can be troublesome :ashamed:

Agh well.... You live and learn....


"Target set point not reached" ;)

Exactly. Cheers :happy2:

Just checking this is the right one for an ed30?

Title: Re: GFB DV+
Post by: ducman77 on August 30, 2016, 10:01:05 pm
As far as I know mate, yes that is the right one :happy2:

You can either fit it on the turbo housing as per K03 three engined standard GTI's.

Or in the front of the engine bay as per KO4 fitted Edition 30's or Pirellis.

Someone more knowledgeable might be able to confirm with more confidence but I am pretty sure the one unit is suitable for both cars :happy2:
Title: Re: GFB DV+
Post by: Dan_FR on August 30, 2016, 10:10:22 pm
T9351 is the correct GFB part for both K03 and K04 TFSi engines.

Worth noting that it's cheaper elsewhere as Awesome will charge you postage on top of that price, whereas AMD sell them for £97.80 delivered on eBay: http://www.ebay.co.uk/itm/GFB-DV-for-VAG-TFSi-Audi-VW-Seat-Skoda-Diverter-Valve-T9351-/271664459868?hash=item3f4076b05c:g:za8AAOxyffZSY63n

Awesome's postage rates are a bit mad!!

Yeah Awesome GTI's postage is a bit of a piss take, especially when AMD will also be paying eBay selling fees on top..... just shows the mark-up I guess. Unfortunately I've had this discussion many times when it comes to how much they mark up the products they sell

Exactly mate. The charge to post it to my house in the south of Ireland was £25!! Crazy. It's a bit silly of them because I would buy lots of things from them if there postage was in line with the competition.

I'm going to ring them and see if they can adjust there rates. I'll let you know if I have any luck :smiley: :happy2:

Ordered the GFB D+ and a cam follower.... unfortunately I missed the ebay links so have paid the postage. Car is booked in for service on Saturday though so as long as they arrive before then, which they will as I just got a text from DPD saying they will be delivered tomorrow, then all is good!

Just fitted a GFB DV+ to my Ed 30 and can say as others have it is a definite improvement in throttle response so IMO worth doing thanks to AKS Tuning for the well packaged and prompt delivery of it

Post by: 6waysforward on November 20, 2016, 04:16:52 pm
When i bought my gti it came with a new gfb dv+ but the guy had never fitted it as he said he had recently changed the dv.

Anyways long story short, i thought i would check it and it had indeed split so i fitted the new dv+ and i can confirm the car runs much smoother with it on. And the power delivery is better as its getting all of its boost now.

It can be changed just by jacking up the car and supporting with a axle stand. No need to take the wheel and inner arch off.

Yes it makes the odd noise on full throttle but its barley noticeable...........Until you fit an open cone filter. Now its noisey  :smiley:

Maybe I was expecting night and day?

I'll describe where I noticed the difference.....

When I bought my ed30 it was already Revoed and had a revision D in it.  Literally a few days later I took it up for remapping and a DV+ was thrown in as a matter of course.  All was good in the world.

Roll on 6 months or so and I switched to a Revision G, just because everyone was raving about it and I had a flat spot appear, so was trying to rule out the DV.

Literally, from the first press of the gas in 1st, the car felt less responsive with G in it.  And after a day's driving around, I took it out and put the DV+ back in.  Responsiveness restored!  Like you say, it's not a night/day difference, but it's certainly noticeable.   

It's clear to see why that happens when you watch the vid!  The OEM DV is either open or closed, so any residual over boost left in the pipework and plenum after a part throttle dump that could aid responsiveness, gets dumped off.  The DV+ keeps it there  :smiley:

Once you're in boost though, I agree, no difference over stock G.   It's just getting into boost feels more pleasant with the DV+.

Having said that, I might bung my G back in this weekend just to make sure I'm not imagining things  :grin:

You're not imagining things @Pudding (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=10733). I share the same experience. I went from a like new rev G to the DV+. Much better partial throttle response from the engine. :happy2:

Post by: bonelorry on November 24, 2016, 05:06:59 pm

That doesn't really make sense. There is no reason why a better DV would stop surge
Title: Re: GFB DV+
Post by: Dan_FR on November 28, 2016, 09:23:22 am
More likely the compressor stall noise on lift-off/gearchange when dumping boost rather than the sub 4k WOT surging noise. Due to the design of the GFB it will flow more than the Rev G will and therefore vent a greater volume which should reduce the 'chu-chu-chu-chu' type noise

The DV+ just makes a little mouse squeak when you lift off on part throttle, otherwise it's silent!  It's very subtle though and you can't hear it with the windows up.

A for the tshhhhh blow off noises......there are tshhhhhh noises, and there are tshhhhhh noises!  A big turbo with a big TIAL 50mm bov makes a cool noise, but a little turbo with little bov, not so cool!

Dude get a DV+ you won't regret it :happy2:
The forge spacer sounds so crap. In all honesty it sounds much more like a bus releasing pressure from it's brake air lines than it does a proper big turbo dumping excess globs of turbo spool juice :rolleye:

As others have said the DV+ is not night and day (unless of course your diaphragm is split) but the boost response and transition is so pin sharp compared to an OEM diverter that the  more time I spend with it the more i love it :love:
