Hi. The boost seems to have dropped on my GTI. I had the diverter valve checked at a dealer and he said it was fine. However he also said that they had never seen a problem with these valves and that it was just forum hysteria. I'm guessing he was talking crap. Does anyone have any other suggestions as to why the power is down?
Cheers

Could be an intercooler pipe has disconnected.

Thanks for the advice, I'll check that out tomorrow :happy2:

It is certainly not forum hysteria! The OE Diaphragm valve splits after a very short lifecycle. The replacement plastic valve doesn't split but by design even when new, leaks boost. Luckily there is a now a solution to this problem from GFB. They have just released (as of last night I was the first uk dealer briefed on this new product) a patented replacement valve that keeps all the advantages of solenoid operation but will last indefinitely and hold as much boost as you throw at it.
I'm hoping someone would like to try one of these valves free of charge and report on the outcome?

Yes! That will defo help. :laugh: he also drove it once as well I seem to remember, so as long as this valve won't turn to dust for lack of use, Mike would be a great test mule.

Excellent! please can you drop me an email and I will get one to you . Please email the address on my homepage
They reckon this valve will last a lifetime - the "new" factory plastic one leaks so badly you can blow past the seal. Finally an aftermarket part for those into tuning and performance and those who just want longer life and lower cost who don't want to "modify" their car. This is the dumpvalve equivalent of a cotton gauze airfilter!

Email inbound. Julian is it?

Email inbound. Julian is it?
yes indeed. 10 years next year, and still just moi doing everything (looks for headbanging smiley)
-
Is there any indication of price for the valve?
I'd be very interested to try one out. I've recently changed my DV from the rubber diaphragm variety to the newer 'G' and
believe throttle response has become less crisp with the new valve. Perhaps this new addition is the long term answer.
Look forward to seeing a review at least.

Hi
yes £97.80 inc - £104.99 delivered.

Is it the same for the Edition30?
-
Interesting. :popcornsoda:
-
£105 and you still have to use half of your original divertor valve and assemble it yourself :laugh:
-
Seems a little dear..... :confused:
-
MMMM thin I would be interested in this. I think my revision D is rubbish. Am I correct in thinking the revision D cracks so you end up with the same problem as the diaphragm splitting?

If still need testers il try otherwise I need tomdomsomething about mine
-

yes all TFSI and FSI 2.0 use the same design. I think it's excellent value for money as every other solution costs more and delivers less. There has been a lot of design over many years and tooling to bring this to market and I think the price point is less than any regular piston type valve. When you buy the new valve from VW you get the solenoid as well but seeing as this doesn't wear it seems rather wasteful.
Dyno reports are showing more torque across the rev range - if this is taken into account it seems like even better value. After all it's only about the same as one tank of petrol. :driver:
-
I could be interested aswell depending on feedback, I'm having boost issues at the minute and this could be one factor contributing to it
Any chance of a group buy on them?!

More torque.... i just dont believe this ONE bit!
Send me one Julian.. and ill take my car on a RR at my cost and get some conclusive evidence. (mikes car will be sat at AKS for the next 6 months...... oh wait, someone made that joke already? )

thanks for the feedback. Clearly if compared a valve that isn't leaking it's unlikely to make more torque. The OE diaphragm valve if not split was probably not what was used as a comparison (i don't have the results yet from this German RR test). The plastic valve though does leak all the time so clearly replacing it with one that doesn't is going to yield more torque...
I'm sorry but it was first come first served and Mike got in their first. At present I am not sure there will be group buys as they are already struggling to get production to meet the initial orders placed by dealers and distributors. I am hoping to get my stock soon. I know the valve for Mike is here this week but I am not sure about stock yet still possibly 2 weeks away. I am taking advance orders though.
thanks again
Julian
-
I'll endeavour to RR. Or at least log the results. Then test at Cadwell or blyton park
-
there may not be any outright gain but it might spool a bit quicker. Will be interesting to see the comparison.
-
I just dont see how that can be the case..... I will be (as always) sceptical until facts are presented.
-
if the DV releases boost faster than a factory valve under a closed throttle and then seals more efficiently and faster, then peak boost can be returned more quickly through the gears - something a WOT pull in one gear on RR won't demonstrate but which can certainly be felt.
e.g this is how their TMS valve works and this image compares the TMS valve to factory valve on a 200SX
(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fgfb.com.au%2Fimages%2Fstories%2Ftms-respons%2Ftms-respons-image-2.jpg&hash=e0f01cf533f64ef0619fc64f06900a4df015eae4)
The DV+ wont make the solenoid move any quicker but the seal is more effective than any of the OE valves
-
Shame about the price point, if it was closer to the existing cost of a DV these would sell very well.
I made the same amount of boost on the Rev D as the Rev G... g replaced d.

But the DV+ wont make it operate any quicker..... as the actuator/solenoid in the DV is not being altered. It may seal better yes....

Long time lurker here. I have now got the GFB DV+ as the guys from GFB were at the shop when I was there
I got it fitted at JD Engineering in the Netherlands. The rolling road comparison showed a marginal increase in torque of a few N/m.
What is more important to me is reducing leakage. I had the latest plastic piston type valve in my car. They fitted my valve to a alloy block they had made up to check valve leakage. I wasn't aware that it leaked so much. Taking the piston apart I suppose I should have known. The plastic 'sealing ring' seems to have at least a mm tolerance. The guy from JD engineering said it was like having a 6mm hole in the intercooler.
So while power might be marginal (but measurable) what was more important to me was leak reduction which will reduce turbo rotational speed and therefore reduce heat.
Well, put it this way, if you had a small intercooler leak, you would fix it. So why not fix the diverter valve leak? The GFB parts has life long warranty, so it was a no-brainer for me...
-
^^^^ Very good write up and description of the DV+ plus points. :happy2:
(although it does sound like you work for them :laugh:)
-
Thanks for sharing your findings.
I would trust JD, they have some mega performance engineering under their belt! The guys responsible for the twin charged blue Mk4?

Sold here too.

However I still think it's in the realms of plasma coils and astronomically expensive especially when you need to strip your existing DV to fit this. I didn't pay too much more for a full DV relocation kit!
I'm happy to be proved wrong about it. But I could replace my existing DV twice for one of those and probably more if I was to buy the diaphragm type.
I wonder if it overcomes the problem that the forge one suffered in needing a service to stop it sticking open after a while.
-
I never had any dramas with my Forge one. I'm back on a G version at the moment. Sold my forge to try the forge super size but but car didn't agree with the supersize valve at all
I plan to fit the valve upgrade at blyton park to do a before & after

Real world test... be good to hear your thoughts on it. :happy2: I seem to have a fair few DV's laying about the place, so stripping one to use with this kit isn't a prob.
-
Lee Maylon (Silver Cupra K1) has tried one from Amd.
"They did a RR before and after fitting, but won't tell me results til I've fed back to them. He said the results were good :P
Drive home was busy but I had a few blasts. Noticeable improvements in throttle response, I think it improves the reaction of my linear throttle.
Good quality kit too.
Not sure if there is more power but it feels like it pulls stronger to the redline."

Just to clear something up. The DV's go, in order
Diaphragm Type
06F 145 710 A > B > C >G
They then switched to the piston type which was a replacement for all diaphragm types (It came after G Rev diaphragm type).
06H 145 710 D
They have a new piston type which is fitted to the TSi engines. The part no. for which is 06H 145 710 C. This has the outer cone from the D version removed. No idea why as any other revision fits the IHI Turbo on the TSi.
The C Version is on the left

You could have 3 Rev G DV's for the price of this new fancy DV+. You might as well just use either one of these for it. No worries about any boost then and they are about £15. But i wouldn't recommend it :laugh:

so if you go into a VW dealer they will supply a piston type but the diaphragm type is still available? One thing is for sure with all these revisions they know there is a weakness. What is the aluminiun ATP product at the bottom of the post? I suppose the key thing is in time the diaphragm type will split and leak and you may not realise for some time whereas the DV+ is a fit and forget part. Unless you just put the diaphragm type in as a service item to change with your airfilter and oil for example. Then many of course fit cotton gauze type air filters at 10 times the price of OE paper for the same reasons. Better performance, longer life.

I've had my rev G. On for about 2 years now running about 1.3bar. No issues what so ever
It's not a service item than needs replacing every 10k. It just something that needs checking once in a while.
Any feedback from mike yet?

Been chasing my tail with a steering electronics fault. Think I've gotten to the bottom of it. Just need to pick up some different MFSW buttons tonight.
My car boosts quite hard with no noticeable Ill effects on my RevG but am keen to see if there's a noticeable difference
-
What was the Elec fault mike? :sick:
-
Horn & MF buttons packed in.
Tried New buttons, new loom, CH controller, new slip ring.
The new buttons I tried turned out to be faulty :fighting:
Put some different buttons in last night, got my horn & buttons back....
However, lost access to my menus on MFD :grin:

Hi Rich
I think you want one of these but don't want to buy one. The man from GFB said he'll give you one to trial
For everyone else if we can sell 5 then I can offer 5% off - I expect I can also save on shipping - just need to get a quote from the post office - special delivery is £8 but signed for will be about £6
For 10 or more then we can do 10% off the the price
cheers
