I have a D revision DV fitted and was wondering if i would be better fitting a G revision DV. I know VW are remaking these again. I have seached the forum and there are differing views on both. Has anyone on here done what I am thinking of doing?
-
I've changed from a D to a G recently as I was impressed with Nick's (Rtech) tests regarding leaking.
Can't say that i've noticed a real difference when driving - it's not like replacing a torn DV with a new one. I think i've noticed a slight difference, but it could be placebo, decent tank of fuel, cooler day etc.....
-
I've got my "G" in the shed and may give it a go, I'm sure I can hear a bit of a hiss on WOT with my "D" :sad1: no loss of power though!

I must admit with my D I occasionally here it WOT and sometimes on gear change but its every so often so I'm going to keep my D on until it happens all the time and get a G as its cheaper
-
I just changed mine last week - was nothing wrong with the d but I wasn't sure if it had ever been changed and the car is 5 years old. The G feels more responsive, car holding boost longer and even the mpg has improved.

D is piston type all the 09 on K04 motors have these as standard, G is back to a rubber diaphragm ( it is actually the older revised 2nd generation K04 DV before VAG went to D
I would imagine the D's are not intended to be fitted into the hot K03 turbo as the plastic might not be happy after a while in the hot enviorment (even though its fitted to the cold side of the blower) this is prob why they don't do the D's even on brand new MK6 GTi's they have the G fitted
Wow sounds confusing !! :confused:
-
I've had a d revision on for the last year and a half, wasn't unhappy with the d, when I serviced on the weekend I changed back to my original can't remember the version but original green diaphragm type. I have to say that the cars picks up boost much quicker than with d and peak boost on the polar was 700 with the d and now occasionally see 900-1000 mb.
My personal opinion is diaphragm is best at least on k03 or should I say my k03! :popcornsoda:
Stevo the d on my k03 showed no sign of melted plastic. :smiley:

Im changing my D tomorrow for a G. I logged today my N75 duty cycle a few times and Im not sure if something is sticking or wtf, because time to time my N75 duty cycle doesnt drop below 90% at all during a 3rd gear pull. But I did also have a really nice 60-70% range results from a 4th gear pull, so its not consistent which is not good at all for error hunting.. Either way, I want to try a new one if it fixes my problem. Maybe I should start a new thread, but since this is close enough.. Does anyone elses DV rev D had problems like this? Could it be something else?

Phew! I'm now confused but am kinda glad I have a Forge DV.

What do you suggest for a 08 ED30 then? Mine had/has a G, changed it to a D a couple of months ago with no difference so was going to change back to the G after being told by the main dealer exactly what you just said. Surely if VW are happy with the G in the Mk6 then it sholud be better on a k04?
:happy2:
-
Surely if VW are happy with the G in the Mk6 then it should be better on a k04?
:happy2:
....Yes if your car is still standard. But best not to take VW's word as gospel if your car is remapped.

I've never fitted a D to a K03 so can't really say, maybe the D won't seal in the K03's housing properly ?? I'd have to play about a bit to see why your having the issues, I would imagine its as simple as that.
Maybe the requested boost can't be made with a D as they leak due to poor sealing on the K03 housing ..
-
I think I will fit the G revision and see how I go. I get a whistle every now and again from the DV when under load so I am sure it is allowing boost to leak passed.

No disrespect but I have some real bolloxxx with Forge DV's leaking. :P

I guess I must have been lucky so far with my Forge DV. JKM fitted it in ~2006 (? - when they first became available) and they have checked it on a couple of occasions and also data log my car regularly.
-
Think your probably right stevo the d and the diaphragm type have completely different ends too them in shape so might not be sealing properly, I also have my n75 duty cycle up next to boost on the high line, the d barely registered more than 0.7 under normal driving half to 3/4 throttle and 700mb. The diaphragm shows n75 duty cycle at lower throttle and higher values yet builds boost quickly and can hold it to higher levels so maybe its a combination of the d type and the rest of the housing in the turbo not being matched and in the k04 with relocation the whole housing is different to work with the piston type.
All i know is that since changing back my car feels a lot more lively and fun to drive, im getting less lag and quicker pick up and the lift off noise is back for when i want to be childish! :signLOL:

Robin, is the forge one the same for ed30 as it is for gti?
any idea where i can find one of these?
There seems to be so much swapping and changing from G's to D's to G's again... would it not make sense to just buy the best quality part and fit it once :scared:
edit: i just read the post regarding Forge ones failing :ashamed:
-
.
If you go to JKM's Facebook page you'll see a pic of the very latest OEM revision - It's neither 'D' or 'G'. A quick route is to click my sig > go to my Timeline page > click JKM in my Likes top 5.

Hmmm.... so its the D but without the cage!?
I wonder if they have replaced the plastic sealing ring with a rubber one then?
Wonder what part number it is too
-
Right
Now i am seriously confused. 1 minute people are saying get a D as the G rubber falls to bits and VW are not doing them anymore....Now people are saying get the G cos the D isnt up to the task....
So which is it D or G?
Or does it simply depend on the year of your car?
-
I think that it is best to summarise as:
Rev D - plastic piston, less prone to failure, may leak boost due to design
Rev G - rubber diaphram, could (will) tear/rip over time, but holds boost better.
:happy2:
-
.
And to add to the confusion I don't think the very latest one is either D or G. Ask JKM - They'll know because they have posted it on Facebook.

Someone has asked for the partno. on facebook... will post here when it's answered...

Statlers changed mine to a G, I have a stock of them just in case, lol!

Ive got a G fitted, since 05 lol, so was going to fit a D as i have one, But now im think do i just replace it with another G?
-
I can't add any statistics but my car (KO3) felt a lot more lively with the original diaphragm DV, than it does not with the revision D, particularly around the top end where is just seems to run out of steam sooner.
-

G fitted today. N75 duty cycle looks to be back to normal. Great, but now my dsg clutches are slipping during upchange 2->3 and 3->4. Bloody hell, maybe Ill just trade the car for a mk6 or Polo GTI. Rant óver and our

Thanks :wink:

I put a fresh "D" about 2000 miles ago. The DV noises were nearly gone altogether it was so quiet.
On the track last week it started squeeling like a pig in 4th and 5th WOT. The DV let off noises gradually lot louder as well
It stopped squeeling on the road but the DV noises were much louder than when it was new. Its now been replaced with a "G" and feels spot on

Glad that G I sold you is working well :happy2:
-
This is hilarious.
All the hype about splitting diverter valves and how important it is to upgrade and now everyone is going backwards surely.
Guess there will be lots of rev d popping up in parts for sale.
I may jump on this and go G but I need some hard evidence not "it felt better," to :happy2:
-
I did mention in my first post on this thread that R-Tech have smoke tested the D valve and found that it can leak boost. They now recommend the use of the G valve over the D valve.
A reputable tuner posting their findings & opinion based on testing was sufficient enough evidence for me :happy2:
-
"it can" does this mean it does leak or it "could" leak just like the g "could split" and leak more boost ?
Sorry if it comes across rude but I'm just a little bit baffled as to why it has taken this long to come to this conclusion.
Hopefully you will see where I'm coming from as I'm not knocking anyone's work just find it all very interesting.
They should do a back to back 10 rev d and 10 rev g and then see which is more consistent in loosing boost
-
Totally agree with what your saying, and don't find it rude at all.
It is odd how seemingly everyone jumped on the piston bandwagon, and now seem to be reverting back to the diaphragm valve. We need someone with a boost gauge to perform back to back tests to compare.
I'm happy with RTechs findings regarding the leaking D valve, and happy to accept that any rubber diaphragm valve will eventually split. My understanding is that boost is held better with the G valve, but it will have a shorter life than a D valve.
For £30, I'm happy to consider it to be a consumable part and will check and replace at each service (if required) :happy2:
-
^^^^ completely agree. It's a replaceable item and not an expensive one either. As I posted previously I had a G originally, went to a D, back to the G now, both in A1 condition so am staying with what VW put on my ED30 (or at least until it goes pop).
:happy2:
-
What kind of pressure can the G take? Don't wanna fit one for it to go pop... And are they less prone to failure on ed30 due to being away from heat?
My C looked fine when I removed for a D, wish I hadn't jumped so quick on the D bandwagon...
Interested in spec on new version on 2012 TSI engines...

Im running a G version (diapragm) and no spits yet... running stage 1 map.

I have major problems with the Forge DV's sticking slighty open at idle , this then lets unmetered air back through the intake which the AFM cannot compensate for.
It basically cause's irratic idle issues
All my big power cars don't have these fitted simply because of this. The supersize are even worse!!! :sick:
I've lost count of the amount I've changed
(I do like their nice coolers though) :innocent:
John was telling me stories today of you being marched to a cash point by the Poliza on the way back from the ring one time, made me laugh mate
I'll have to try and get over there with you lot this year :laugh:
-
Well JKM have just said its 06H145710C but that cant be right as that was the old green rubber one.
-
.
Latest from JKM this morning:
"The old green rubber one was a different part number - that valve began 06F The new valve begins 06H. As far as we can see the new valve is the same as the 'D' but with out the fragile back outer casing as per the picture"
-
The C is listed as the latest dv for the tsi and the fsi is sill listed as being the G. I would presume the cage has been removed as possibly being the cause of the whistle noise these types make sometimes
-
I am glad this thread is helping to clear things up... :chicken:

^^^^ thinking the same thing :signLOL:

As a precaution, I also want to replace my diverter valve.
I've never replaced it, bought the car in 2010 and I don't know if the first owner ever replaced it.
The mk5 gti is from 06-2005.
Everything is stock, except a stage 1 ABT remap.
How to check if my old DV is 'faulty'?
If is is faulty, is there always a faultcode (I have Vagcom and have no faultcodes).
What version DV (complete partnumber) to order at VW?
Is there a how-to, to replace the DV on the original location?
-
Ive used Rev D (which replaced the 06F C) when i got my eddy 3 years ago, then changed to a forge dv and now am going to try the Rev G....will give you the heads up after ive taken her for a few runs, i'm stage 2+ REVO.

Best way to tell is to just take it out and check it for any splits. You have the older diaphragm version I imagine as your GTI is the earlier Mk5, so you "could" go with latest piston one, Revision D or as many of us are now doing you could go with the Revision G, more than enough for stage 1 IMHO. If it goes pop, there only £50 ish for D and I think it's even cheaper for the Revision G.
Part number for Revision G is. 06F 145 710 G
If you want the Revision D, it's 06H 145 710 D
You might find this thread helpful for changing it and diagnosis. :happy2:

I thought the D was still 06F 145 710 D
but you might aswell get the 06H 145 710 C

Got my D from eBay, the fella is still selling them, part number from on the side of valve is 06H 145 710 D. Less than £50 as well, been selling them for months and really good (nothing to do with me)!!

Thank you so much!
I'm going to buy a new diaphragm 'G' version, because I read that some say the piston 'D' version is maybe less prone to failure but doesn't feel as lively as a diaphragm version (less boost).
Going to check my original dv if its torn.
-
Unless u REALLY know wat u r doing, id get a Specialist to do it!
-
Its 3 allen bolts you really don't need to take it to a specialist, ed30 is even easier you don't even need to go under the car.
I didn't fit a g either the original one off my 05 car, I don't have cds logs but i have the polar fis and see boost and n75 in real time and the diaphram type makes higher boost levels and picks up boost quicker than a d.
-

It's so easy, that I'd hate to see someone paying to have this done! It's a 5 minute job if you know where you're looking - if you've got a stock undertray you can just reach under the car and do it.
-
Well for my 2005 GTi, it had to b up on ramps to have it changed, a good 45 min or so, and by a specialist! I understand that Ed30's r much easier and quicker to change...

Really! It's possible to change the one on my K03 in minutes on the driveway! Stick it on an axle stand, drop the undertray, unclip the plug, undo the 3 bolts and job done. Refitting is the reversal. It really is that easy.
-
Guess only simple if u know how, lol! I had that, pcv, and cam follower changed at same time and it took bout hour and a half and excess of a hundred quid! I could in no way have fitted these myself! :-(

You don't even need to do this.. I jacked up the drivers side, wheel off, arch liner out swap the DV's and put it all back :happy2:
-
Guess this may be why i get the occasional fault code:
000665 - Boost Pressure Regulation: Control Range Not Reached
P0299 - 002 - Lower Limit Exceeded - Intermittent
When driving hard
-
Pcv is also easy but cam follower bit more complex. Doing all that shouldn't take a mechanic hour and a half wih ramps, but you have all the know wear points done.
-
Just out of curiosity does the G valve sound different from the diverter D as its a different system?
-
Hmm, a bit worrying they have removed the cage on revision D. i wonder if there were a problem of them they breaking off over time? Wouldn't be good the debris hitting the turbo blades :scared:
I'm running my D over 3 years now and holds boost as requested.
-
Swapped my diverter valve today from d to g.the car does seem to come on boost earlier with the g and car is more responsive low down. :wink:
-
Sure it's not in your head lol :happy2:
-
Maybe :stupid: then again my butt dyno is usually right :driver:
-
Sure it's not in your head lol :happy2:
He may have a faulty one. My D even after 3 years meets requested boost on my ko4.
-
Nope d wasn't faulty as made good peak power on Rtech rollers.the d diverter just seems more laggy on the road.now with g boost comes in earlier put top end wise still the same. It's a simple DIY job changing so all who have doubts just try changing it and c. :wink:
-
I fitted the G revision today and the car feels a lot perkier. It has a rock steady idle again and im seeing a few more mpgs. Normally on a stretch of road i got 26mpg and now it goes straight to 30 mpg on the same stretch. The mid range punch is back and its not laggy low down. There is a massive size difference in the piston lengths between the D and G. The D is about 7mm shorter so I dont think it makes as good a seal as the G. I wish I hadnt jumped on the D bandwagon 2 years ago and should have just stuck to the OE item for the car. Lesson learnt.
-
Definitely thinking of getting the G valve now, too many people giving the go ahead with positive results
-
Anyone wanna buy a rev D lol
