Power loss at 2500 revs

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

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'. 

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!!! 

So are you telling me 100% it wont fit and may cause damage because it seems lots of people have already made the change and the results seem very good.  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 


EDIT: and having a quick look on ETKA - no TSI engine has a G valve!

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.

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

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!

Does anyone know when they started to fit the latest version to the GTI ?

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!

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.
