Hi
I have a 2005 GTI thats stock and my think my DV valve may be leaking. What would be the signs and what would be the best one to fit?
Thank you

Just had this with my '05. It felt low on power. I could feel that the power wasn't there when I tried to accelerate. Like the turbo was hardly kicking in. There was also a whistle when accelerating. The revision G is the one to go for, part no: 06F 145 710 G.

D v G
Round 13
Ding ding!
:popcornsoda:
-
D for the K03.
G for the K04.
-
G for both ko3 and ko4, period!

Yep, that's what I thought! :happy2:

Had this on mine when I bought it and had no clue as I'd come from a Peugeot 307 so power felt great :signLOL:
Only thing I noticed, looking back after it was fixed, was the power would drop off quite quickly and didn't hold boost as obviously the diaphragm was split
Once changed it pulled strong and held boost like it should

The diaphragm on a G seals better than the piston on the D
BUT...
because of differences in the location of DV in relation to the turbo between K03 and K04 engined cars, a diaphragm DV is prone to heat drying out the rubber and cracking on a K03, so this is why the D piston type is better on a K03 car. On a K04 car this problem doesn't exist so a G is therefore better.
-
So if you consider the DV as a yearly consumable and change every 12/18 months, the G would be the one to go for on a KO3 I take it?

....Which is exactly why VW's OEM DV's failed so commonly in the first place and consequently why I bought a Forge DV from the first batch available way back in 2007(?). Failures weren't just on remapped cars with extra boost to handle either.

was changing my Revision D diverter for G today when i saw oil on the sensor connection that plugs into the DV. on removing it there was oil inside, not a massive amount but a bit. is that normal? cant remember there being any when i changed from the B to D
also i am going to have to get 3 new bolts from VW as one of the bolts heads was smoothing out from a hexagon shape to a circle :sad1: so have to wait till tomorrow to get it back on.
-
It's taken nearly 8 years for my original diaphragm DV to fail, so I'm not too worried about the fact I've replaced mine with a rev G. Doubt that I would be keeping the car another 8 years!

Hi Guys
When i drive the gti hard the power doesn't always seem to be there. Sometimes it feels like a rocket other times very slow to react. I only have 49k on the clock and FSH with agents as well as all the extra maintenance i do.
Thanks for the advise.
-
I stripped mine down at work yesterday to check it and yeah sure enough its torn. Rev B
Running a 2005 with BCS system, what would people recommend D or G???
-
^^^^ D. :happy2:
-
I've got a Rev D for sale if your interested. Its only done 16k.

when i changed mine 2 weeks ago mine had oil in it too i have asked the same question was this normal but no answer so hopefully can get an answer on here

Cheers buddy i'll get one sorted at work tomorrow.

was just about to list my Revision D Diverter Valve for sale when i saw these cracks in 2 of the 3 bolting points!

crap :surprised:

I had mine changed just before the remap last Friday and went for a G on my K03. The rev C that was taken off was fine so don't think I'll have any issues with the G and as mentioned it holds boost better :happy2:
-
well i got the 3 new screws from VW today, bolted it on, and i was surprised at the difference!
my old one REV D pictured above with cracking around the screw holes must have either behaved differently or was having a boost leak of some sorts.
the engine feels a little more responsive, but the main difference is the noise the P-Flo makes. It is now a more sucking sound thats quieter, but feels like its doing its job better? if that makes any sense? before the P-Flo was quite loud when accelerating a bit harder in a low rev situation but now its not.
weird. anyway i will test some more but im really surprised at the difference. i thought it wouldnt be anything at all that i could hear.
-
G revision for both K04 and K03 the D versions leaks straight away some are leaking even before being fitted to the car...
The G will last a few years and cost less than 40quid to replace "IF" it splits, but I have 100s of K03s running the G and so far I have had no reports of one splitting.
-
Have D fitted on mine, but have a G in the cupboard... by all accounts, D won't fail like the diaphragm models do (tearing) but do leak, which is as good as, isn't it --- go for G, asnd think of it as a replaceable part every 18 months or so.
-
^^^^
Golly! I thought that VW had at last solved their very longstanding DV issues. Hopefully they have done so with the revision G.
I'm glad to say that my Forge DV has so far lasted without any issues for what must be about 6 years - I had one from the very first batch.

Hi
Just checking if this is the right part number? 06F145710G

Bad advise G as the Ds dont seal, and the idea of the DV is to seal under load.

From what I have read on here, that sounds like the PCV... read this: http://www.mk5golfgti.co.uk/forum/index.php/topic,44709.0/topicseen.html (http://www.mk5golfgti.co.uk/forum/index.php/topic,44709.0/topicseen.html)

What's the cost of these DV'S and also cost to fit at an Indy or dealer ?
-
Grab a G
Between £30 to £50 depending where you buy
To Fit:
K03 is wheels up
K04 under the bonnet
30 mins either way, tops.

My indy charged £90 all in for fitting a rev g. That included scanning for fault and clearing.

This is the DV on a Ko3. The black thing to the left with the two wires coming out of it. Had it replaced this morning.

I replaced it with a rev G as I am not gonna be doing any performance upgrades any time soon. The car is SO much faster now. The rev G cost £38 roughly inc. VAT and I had my sisters boyfriend fit it at his garage for a tenner.
