Acting on some sound advice from Sambo I had the diverter valve replaced on my '06 GTI. Got my mate to order one up for me - it's the latest 'D' spec part off the newer TSI engine. He fitted it while servicing the car at the weekend.
Having inspected the old part that came off the car, the rubber diaphragm wasn't actually split (supposedly the main weakness) however with the new part fitted the car is so much nicer to drive. At anything over 4500rpm it pulls much harder and the power doesn't fall off like it used to past 5200rpm. :smiley:
For the price of the part, this is a very worthwhile mod so thanks for the advice.
-
How much are they?
-
I paid about £40 but my mate works for VW so gets discount. I guess it retails at £50 - £60?
Part number is 06H 145 710 D
Not sure if it will fit the ED30 though, it fits directly onto the turbo and I'm pretty sure the ED30 has a different turbo to the regular GTI.
It took him about 5 mins to fit it.
-
I paid £26 from a NI dealer.
-
Maybe I have better get one of these - now it is REVO'd!
-
Probably a good idea. Mine is just a standard 200ps but apparently remapping encourages premature failure of this part.
I did consider the Forge motorsport DV (which itself if a lovely looking piece of kit) but personally prefer to stick with standard VW parts, especially as the car is still under warranty.
Also, the latst spec VW part has been completely redesigned so it doesn't have a sh1tty rubber diaphragm in it (which splits over time). I did read somewhere that it's the recommended replacement part in cases where the old style part has failed.
-
Certainly made a differance to my car too, although my original DV was completley knackered with mutiple splits in the rubber! :undecided:
Can only assume that because it's designed for a small engine with supercharger/turbo it holds the boost for longer so the little 1.4 doesn't struggle at the top end of rev range?

I have the D revision and it is much quieter than the rubber sink plunger version and seems to offer the same performance as the forge.

Its designed for the new 2.0 tsi in the scirocco and new gti. Its actually quite a different engine
-
Is there an idiots guide to fitting this somewhere (had a quick look in the maintenance section) - I actually want to check the condition of mine to see if it has split as I'm hoping this is the reason for my car feeling "sluggish"
Also is this the same as the re-circulating valve or different??
Soz to hijack - same topic though :laugh:
-

Yes it does seem much quieter than the sink plunger version, you can hardly hear the pressure release when you back off the throttle (which suits me as it's not to my taste).
-
Also is this the same as the re-circulating valve or different??
I think its the same, I think its also called a cut of valve.
Forge used to have a guide for changing the DV on the 1.8T, maybe they have the same for the 2.0T. If its the standard GTI you have to get underneath the car...

It's designed for all 2.0T engines as it supercedes existing ones, it's the only DV you can get now. I ordered mine as a G valve and they sent me a D.

Actually, from what I can tell, the Recirculating Valve is what we refer to as the PCV, the DV is in fact an EGR cut off valve.

Is this the one?

Later models (not sure what year this came into effect) and ED30s have them located in a much easier place and can be replaced via opening the bonnet.
-
LOL they are having a laugh at those prices, rip off! As i said i got one from a dealer for £26.
-
You got a D valve from the dealer for £26?

Yep, i got it sent from a dealer in NI, 26 + 4 or 5 for post.

Was just a general request - thought you might have had the easier bonnet setup so could take a pic :grin: Just ordered a Haynes manual so hopefully that will point me in the right direction - you guys know way too much about what goes on under the bonnet :embarassed:

lol no, mines a MY05 so had to get under the car to replace mine.

It's designed for all 2.0T engines as it supercedes existing ones,
WRONG. It was specifically designed for ONLY the latest Audi-developed TSI engine with valvelift - as the part number clearly designates!
it's the only DV you can get now.
Wrong again. The current part number for the original 200/230/240/265PS TFSI engine is still valid, and is still 'orderable'.
I ordered mine as a G valve and they sent me a D.
Ever heard of humans making mistakes? :wink:

Actually, from what I can tell, the Recirculating Valve is what we refer to as the PCV, the DV is in fact an EGR cut off valve.
Nope, that is wrong. IIRC, the 'correct' term VWAG now use is 'turbo cut off valve'. This is also commonly known as a 'recirc valve' or 'divert valve', and also incorrectly known as a 'dump valve'. This simply deals with excess boost pressure from the turbo.
The PCV is actually a 'positive crankcase ventilation' valve, and ONLY deals with excess pressure build up in the crankcase (usually caused by 'blow-by' gassses). This has nowt to do with the turbo.
And EGR is 'exhaust gas recirculation' valve, a device for emissions control !!! :nerd:

Sorry to seem beligerent, but it's important to get the terminology right when ordering parts.
You're right, in the workshop manuals it labels the valve at the front of the engine on the top of the manifold as a PCV ('pressure control valve'), but if you talk to VW they won't have a clue what you're talking about. That part, as far as they are concerned, is called a Recirculation Valve (or 'Recirc Valve'). I know this because I spoke to them today.
As for the DV (Diverter Valve), this is again not a term that VW will understand, they know this part as an 'EGR cut off valve' and if you ask for the latest part number, they will quote you '06H 145 710 D'.
This latest part (designed for newer 2.0 engines) superceeds all previous versions and even though it wasn't specifically designed for the MK5 GTi engine, still works with it.
Again, I know this because I had it fitted last month.

From my (very) recent experience, if you try and order an older version of this part from VW, they will tell you that it has been superceeded with '06H 145 710 D'. I have this part fitted on my car and it works perfectly, improving dramtically the B version that I previously had, even though this B version was (visibily) undamaged or ripped.

[/quote]
Wrong :wink:, it IS the only DV that is available now as it supercedes the older version G, i have a friend who works in a dealer and has confirmed it. Unless of course the dealer or VW :wink: has old stock they want to get rid of then you will get the older one :wink:
Yes humans do make mistakes but not in this case

Erm . . . . you might want to read my sig. I certainly know the correct terminology for specific parts, and I certainly know the difference between said parts to! :rolleyes:
You're right, in the workshop manuals it labels the valve at the front of the engine on the top of the manifold as a PCV ('pressure control valve'), but if you talk to VW they won't have a clue what you're talking about.
Just because some thicko at a dub stealer doesn't know the correct terminology, that doesn't mean that highly qualified and conciencious persons should be 'dummed down'!
I'll state again, a PCV has sod-all to do with regulating boost pressure from a forced induction system! :rolleyes:
That part, as far as they are concerned, is called a Recirculation Valve (or 'Recirc Valve'). I know this because I spoke to them today.
Well that just proves they have it wrong. For ages now, ETKA has that part listed as a 'turbo cut off valve', however, it used to be called either a diverter valve or a recirculation valve - and VWUKs own parts ordering system may still be using the 'old' terminology.
As for the DV (Diverter Valve), this is again not a term that VW will understand, they know this part as an 'EGR cut off valve' and if you ask for the latest part number, they will quote you '06H 145 710 D'.
Sorry, but that is utter horse sh!t. A 'DV' and an 'EGR' are two very different components, and work on two completely different areas of an engine. Someone really is talking out of their tail!
This latest part (designed for newer 2.0 engines) superceeds all previous versions and even though it wasn't specifically designed for the MK5 GTi engine, still works with it.
Again, I know this because I had it fitted last month.
Just because a part 'fits', it categorically does NOT mean it superceeds it. The piston DV was specifically designed for the Audi valvelift engine, which is in the new 'Rocco', and the Mk6 GTI - which is why the first three digits of the p/n are 'ahead' of the p/n range for the 'Mk5' TFSI engine.
I accept that some peeps have fitted the newer piston DV to a Mk5 TFSI engine - but I can categorically assure you - this is NOT an official supercession!
-
too say it will ONLY work with the new tsi engines is tosh, its been running on mine since Jan with no problems at all
number of people on this site and others across the world have gone to VW garages and ordered the DV and received the D version for their mk5 gti
I can understand people make mistakes but for it to happen over and over again like you are suggesting then either you are wrong or vw garages across the world are wrong
you know your stuff tt, but I would double check and check again with your sources
-
Hi hope I can join in, the older DV valves have been superceeded to the new piston type valve.
Yes some dealers may have old stock but unless something has changed within the last couple of weeks if the old part no is typed into ETKA then it will superceed to the new D valve.
All the latest TSI engines -1.4 and 2.0 litre are coming from the factory with this valve fitted.
Just out of interest the latest 2.0 tsi engines in the Golf and Scirocco are not (as yet) fitted with the valve lift system, probobaly why the 2.0 tsi Audi A4 fitted with this has lower CO2 and better mpg figures than the Golf. :smiley:
-
Another heated conversation out of nothing :grin:
The D type which is fitted to my car was NOT a superceeded part when mine was which was last month. Think it was still listing a G type? not sure but I had to request a part that the VW computer was not listing for my car using the part number. Wether or not this is still the case I don't know, but I have a very god friend who is a master tech and i'm quite friendly with the part's guy which my friend also knows very well, so between the 3 of us there isn't much bullsh!t. :kiss:
The PCV valve was listed as positive crankcase ventilation valve on the vag computer as this was listed as the suspect to my dodgy idle which turned out not to be. As far as I can make it it is basically a crank breather valve like many cars have similar too.
HTH Sam :smiley:
-
This is the most interesting thing to happen on the MK5 board for ages..........
It's a good job we're not at the pub as I fear that people would have been asked to "take this outside" by now :grin:
I think the common sentiment from those who have the 06H 145 710 D fitted is that it's a popular and effective replacement for the original item and it appears to give a slight improvement in performance and driveability.
-
Just get the Forge one, much easier lol :D
-
I ordered mine as a G and the invoice has the G number on it, it had to be ordered in as they hadn't it in stock and that's what was sent to them :grin:
Anyway it works exactly as my old G valve did before it got ripped a new a**hole :grin:
-
Just get the Forge one, much easier lol :D
As it happens I have tried both as I (wrongly) suspected that my forge was sticking and I can't tell the difference between that and the TSI D version.
-

The forge one requires maintainance, is more expensive and makes the engine less responsive...
-
Dont get the Golf Haynes manual - it sucks - couple of pages on the turbo system and nothing that useful - if anything I'm even more confused now. It talks about "Boost pressure solenoid valve" and "Boost pressure Valve (wastegate)" - assuming the later is this DV?? - Haynes comment on the later:
"The boost pressure valve is an integral part of the turbocharger, and cannot be renewed separately" I'm off to set fire to it then back trawling the forums!
-
too say it will ONLY work with the new tsi engines is tosh,
Erm . . . who said that? Because I certainly did NOT.
What I actually, and categorically stated - is that it was specifically designed for the new TSI engine. So hopefully anyone who has a basic comprehension of the English language can see the difference in those two comments! :rolleyes:
its been running on mine since Jan with no problems at all
Again, I have NOT disagreed with that bit. I freely accept that some peeps are using the new valve on the older engine without probs - all I have stated is that this is NOT an official VWAG modification.

<yawn again>
You arn't referring to Yanks, are you? If so, sort of says it all really!
you know your stuff tt, but I would double check and check again with your sources
I'll gladly check again, but remember, I do have an official trade account with VW UK, and my local TPS are always able to vouch for my 'factually correct' info. But if the situation has changed, then I'll gladly report back and eat my slice of humble pie.

Got a picture of it's position I took on my phone today if it's any use. Was taken whilst doing the cambelt (nightmare) today so managed to get a snap especially for you whilst it was on axle stands :kiss: :grin:
Sam
-
Cheers Sam - any chance of putting up on the forum?
-
No problem, it's actually quite a hard place to get a photo of that is easy to understand where it is positioned :embarassed:
The DV is located in this area of the car
(http://i38.photobucket.com/albums/e114/sambotc/car-outline.jpg)
This picture was taken from the drivers side wheel arch with the wheel and inner arch liner removed. The DV is bolted onto the turbo via 3 bolts (obvious once you have a replacement part in your hand)
(http://i38.photobucket.com/albums/e114/sambotc/dvtfsi2.jpg)
The turbo is on the back of the engine to the slight left if looking from the front of the car into the engine bay. You need to be able to get under the car to undo the bolts.
This is a close up of the part to give you an idea of how it is attached to the turbo.
(http://i38.photobucket.com/albums/e114/sambotc/dvtfsi.jpg)
You can see there is also a boost pipe removed in these pictures, but this isn't needed to fit this part, it's actually a straight forward job once the car is in the air and your underneath.
HTH Sam :smiley:
-
Fantastic - thanks Sam. Will get it removed and have a good look around at the same time - hopefully this is my problem :cool:
-
i did this today and i gotta say im amazed at the difference it made!!! the old one was shot to bits and split
Had the new one fitted and i was away and loving the power diff!!!
highly reccomend!

Did you replace it because you knew something was wrong?
-
Has anyone done any vag-com logging with these TSI-spec piston valves, and checked for any legacy DTCs? :undecided:
-
Mine was hooked up to a 5052 post-fitment and no fault codes were present.
-
tbh i honest i just did it cos i kinda had a gut feeling it was split , car wasnt performing as it had been. turns out i was right it had split so all well and good.
-
So how much are they??? There seems to be a dfifference of opinion on here.
-
£46 from my local dealer £10 for my mate to fitt it, car has to go up a ramp of somekind. Trust me do it!
-
The only benefit is durability, to me the car feels the same as with the G valve.
-
was urs split?

shameful bump! :embarassed:
Anyway, I still havn't had the time to look into this further, but we need to keep this thread updated, because we need to clear up some of the earlier confusion. :afro:

....Thanks but I found the dozen or more pages of technical discussion on that vortex link went over my head!
The conclusion seemed to be that there was no conclusion but just Forge defending itself calmly and reasonably against calm and reasoned challenges.
Included in the vortex thread was some discussion of the spacer.

Why bother fixing it if it aint broke?
It took VW's magnificent r&d team half a dozen goes to get a decent recirculation valve (type G).
Who's to know if this first version of the new valve is any good?

ok you guys are technically way over my head! my car still seems transformed by this little mod. its going in on monday for a service and will see if any codes are flashing up then. Am i ok in saying im not doin my car any harm with this or do we not know?

As mentioned before, I have done this mod to my car and it did not produce any fault codes. Have been running it for a while now, no issues as yet.
