At around 2-3000 revs i can feel a dip in boost then it makes the whoosh noise constant, more so than it did before.
I have noticed a difference in the sound, that being longer and also the minor power loss?
:sad:
Going straight to the dealers tomorrow.

Sounds like it could be the cut off valve. Part number is 06f 145 710 g. If your car is 2005 or 2006 you may have the 06f 145 710 b version which was weak. Suggest that the dealers look at this first. (although i could be completely wrong)
-
Certainly sounds like the diverter valve. Vw have revised it again with the diaphram removed so high boost doesn't rip it anymore. I'm having it fitted on thursday as a precaution. £38 + vat

Is it usually Manual, DSG or both that split the turbo recirculation valve?
I have a theory.

I don't know if the transmission can affect it since it's boost pressure that would break the valve, right? :huh:

Hmmmmm - as others have said, it could well be your turbo cut off valve (aka divert valve or recirc valve). However, being as you can actually notice an increase in the sound of "whoosh" noise - I would also be inclined to suggest that there may be a physical leak somewhere, which is allowing the boost pressure to actually vent to the atmosphere, rather than be "recircled" back to the low side of the turbo.

Get a Forge one, bit more money but should outlast the car (especially if you want to remap later on).

The nosh-meister has decent question for a change! :evil: :wink: :smiley:
Honestly, though, I doubt there would be any kind of stats to support one or the other in standard tune. Maybe the manuals might be more prone to damage the COV on highly tuned engines, but that may simply be a result of the torque handling limitations of the DSG.
I have a theory.
Welllll - share it then! :nerd:

Yup, boost pressure - but don't forget temperatures too. The higher the temperature, the less resistant the rubber is to damage. Which is probably why the K04 turbos have the COV remotely located at the front of the engine, well away from any concentrated heat sources.
-

I am not doubting the quality (along with the bling factor) of the Forge valve. However, with the current "G" version, VW seemed to have nailed the reliability issues of the earlier versions.
If you want the OEM look, and have a K03 motor, then re-site the valve to the front of the engine for a fraction of the cost of the Forge - and I would reckon that any troubles (providing you do have the "G" valve) would be avoided.

It's not a supercession in the typical sense, where the part goes from an A to B to C, like the original "G" valves were doing. It's a completely new PN that everything's being changed over to, so you can't just call it the "D" rev, since it's a completely different part number than the prior valves. There's a "D" rev of the 06F, and the "D" rev of the new 06H.

OK, I missed the change in part number - but that just confirms that this new valve is actually for the new Audi valvelift TSI engine (which is prefixed "06H"). It wont fit in our TFSI engines - if it were designed to fit our engines, then it would still have an 06F part number. :nerd:
So I am still right about the yanks lack of intelligence! :smug: :smug:

But just to confirm, it does fit both tfsi and tsi engines

well ive been to the dealers, they want £70 to do a diagnostic check on the car as it takes 1hour :huh:!!!!

Screw that! I have vagcom :wink:

If it is just a valve.. which is the most favourable recommended?
i will be keeping the car for a few years yet so want something durable unlike this vw one that has last only 25000 miles!

revision G is much better, unless there is this new one the US guys were on about. Otherwise a Forge will do the job - more money mind.

Sorry, but I have to strongly disagree. If it were to fit the TFSI, then it would DEFINATELY start with 06F. VAG part numbers are not 'forwards compatible'. :rolleyes:
EDIT: checked ETKA - it categorically is NOT listed for any TFSI engine. It ONLY fits the TSI engine which has a completely different make of turbo!!! :rolleyes:

Erm, nothing lasts a lifetime. It may have a lifetime warranty (limited too :wink:), and if sommat on the Forge DV brakes during normal use, then Forge will repair it or supply a new. But it aint indestructable.

And you still need to service the Forge DV

Exactly. At least the OEM G versions are fit and forget.

i think ill go for the OEM G VERSION? any part number?
how ideas on fitment prices?
Im gonna go see Neg when hes free, as he has the vagcom so hopefully it is only a valve, its not much boost loss but is noticeable

VW have FINALLY got rid of the stupid plastic diaphragm in their diverter valves? F*ck me.. only took them 10 years of failing to get that right.

Is yours a standard GTI, or an Ed30 - as the actual location is different?
For the standard GTI and the Ed30, it is "06F 145 710 G" - which fits engine codes AXX, BWA, BPY and BYD. Pricewise, for just the part from a main dealer, look at around £22 plus vat.
Fitting-wise, on the standard GTI, it is bolted directly onto the turbo housing, at the rear of the engine - and is a tad fiddly to get to. On the Ed30, it is remotely mounted at the front of the engine near the top, an is a doddle to get to - probably a 5 minute job!

Ive got a standard GTI... £20-£30 aint bad, im guessing it will take an hour to fit at vw so around £70

I am tempted with Germam Auto for some work I need doing - my mate popped round last night and he recently took his (my previous) Leon Cupra R there - he was impressed and price was good too. Then even collected his car !
Fitting is a pain - you really need to get the car on a ramp (or use a pit) - 30-40mins tops.

I took mine to an independent and he charged £30 for a half hour job. It really does need a ramp as it's a b*****d to get to on the standard gti.

My dealer tell me the system is being updated to show this as the latest replacement, my specialist are telling it will fit fine and companies like ecs for example are selling it to fit all tfsi and tsi engines. see link http://www.ecstuning.com/stage/edpd/pagebuild_v2.cgi/?html=learnmore.html&productID=259456
I am also told the early tsi's have revision g also so if both fit to that then both must fit to the tfsi??
I'm apprehensive now because mine is being fitted thursday and dont want any adverse effect

Hmmmmm, righty - let us try and clarify this.
Firstly - will it physically fit? It very well may actually 'bolt in' and connect up to the electrical plug. But physically 'fitting', and working correctly are two very different issues. As I previously stated earlier in the thread, that valve as described on the yankie site is categorically not for any TFSI engine, nor is it for any K03 or K04 turbo.
Secondly, part number ordering:
VAG have a very clear and well established method for their part numbering system. Take the Mk5 Golf as a whole. It has a "typ code" of 1K - and all parts developed for a Mk5 will usually start with 1K0. For specific right hand drive parts, front windscreen wipers and headlamps being obvious examples, they will start with 1K2. Now, the Mk5 may also have some parts which have been developed and used on previous models - and another specific example would be the rear brake caliper piston seal set - the Mk5 part number is 1J0 698 671 - but the "1J" bit indicates that the part was originally fitted on a Mk4 Golf. But the opposite way isn't true - you can NOT use any Mk5 "1K" parts on an earlier Mk4 "1J" car.
Now, understanding the above regarding the whole car numbering system, you need to be aware that major mechanical components also have their own part number groups - which mainly mean engines, gearboxes, and rear axle final drives. The 6-speed DSG gearbox has a parts group of "02E", a 4.2 V8 petrol engine has "079".
The Mk5 GTI 2.0TFSI engine has a parts group of "06F" - and most of its part numbers will begin with 06F. It may also carry over some parts from earlier engines, such as 06D. But when any parts for the 06F engine are revised, they will ALWAYS begin with 06F. Now, if a newer engine is developed, in this case the Audi valve lift TSI engine (06G) - any new parts specific to this new engine will begin with 06G. But just like the cars, these 06G parts are NOT compatible with previous engines (the 06F in our case).
So, at the end of the day, the part in question may well bolt on - but it probably will NOT work correctly, because VW never designed it to fit that particular engine. So, if you want to carry on and have it fitted - well that is your call - but just be prepared for things to go wrong - and be unable to work properly.
HTH :smiley:
EDIT: and having a quick look on ETKA - no TSI engine has a G valve! :rolleyes:

well i gave the vw guy the part number as stated by Teutonic_Tamer, cost £30 inc VAT..
collecting it tomorrow, will post a photo of it just so you know if it is the latest version as the vw guy didnt seem so sure.

so fitting a DV is difficult..... I had it in my mind it was a couple of jubilee clips and two hoses..... I was quoted about an hour in Drivers Glasgow with the part circa £140.

Well by going on what VW parts said, I presume around late last year? It is still an order only part (well at parkway vw anyway)
He also said a few other minor changes have also been made on the 58 plates.

From memory I would say mid-2008 the G revision came out.

Mine was built June 2006 - and that has the latest G version - so they have been around for quite a while now - at least 2½ years! :wink: :smiley:

On the standard GTI - because it is bolted directly onto the turbo housing - you really need to jack the car up, and get at it from below. Not really an issue for a stealer with a ramp or post lift, but for a DIYer, with just a pair of drive-on DIY ramps or a pair of axle stands - then it is a little more tricky.
I really think a very wise mod on the standard GTI would be to re-site the valve to the upper front of the engine, just like the Ed30/Cupra/S3 variants. This way, the valve is isolated from the very localised heat sources, and is also much easier to work on.

Same here. VW wanted 2 hours to fit my Forge one, just crazy.
Got recomended a local place to me by WhiteGTI and he only wanted 1 hour @ £45 and he owns a veeery nice blk MK5 himself.

Try a place called Solo in Burton - he's a VW man.

Well im defo going awesomegti, im gonna wait til week after next as i might get some other parts installed aswell..
Will driving around with the boost fault cause any further damage?
-
Just take it easy as if you get the turbo to boost up, it'll never make the requested boost and will be working overtime to try to reach it.
-
TT would it be possible for you to check this out for me?
"ETKA lists this for the Jetta, and the old G valve for the GTI. Weird"
And also listed for the passat from 05 and the eos??
I presume the jetta is the tfsi and not the newer type. I'm told the passat is also listed for the same part? I didnt get it done thursday due to the snow but this new dv seems to be the most popular mod out there at the moment and many are taking their forge ones off to replace with these?
Thanks

Replacing their Forge one with G spec VW valves? Whats the point, Forge one is just as good if not better.

Its apparently performing better than the forge but TT has said since its not yet listed as the latest update for the tfsi then its a bad idea and suspects its only designed for the newer tsi engines which have a different turbo?

No replacing it with 06H 145 710 D which is a piston one. The forge seems to have loads of negative feedback, hence people are looking for a better alternative
-
hmm, what negative feedback??
-
Absolutely nothing in that thread except a bunch of dumb americans wanting the new one simply because it is new.
The thing is still made out of plastic for christ sake. Oooohhhh it holds more boost pressure, really dipsh!t, seeing as the car is programmed to hold a set peak boost how does it do that. My car holds peak boost with the Forge DV, it didn't with the OEM one, and I have no doubt after a few miles this one will suffer the same fate as all the other revisions. Its manufactured down to a price, do the math.

hmm, what negative feedback??
I'm on the search...

Also some issues with it sticking in cold conditions, the fact it needs maintainance. On a US forum i read an article where someone asked why there were so many seconds hand ones were for sale and then there was loads of feedback for why they have been removed and sold on. It was all rather bad reading in ref to the forge unit. I'm just feeding back what I've read, I'm not suggesting its fact just trying to understand what is best for my car

I wouldn't be too believing of all that crew says in his posting as he is well known to be anti-forge and a devil's advocate.
The forge valve you refer to sticking in cold conditions is with the BSH DV relocation kit and that uses a much larger and different forge valve and seems to occur with folk who have meths injection in extremely cold temps that we don't see across here in the UK.
