Title: Rev G DV Obsolete?
Post by: PatchySan on July 11, 2016, 01:56:43 pm
Hi All,

Just got my 2005 MK5 GTI on the weekend and am loving it. Doing a maintenance check over so went to the dealer to get some key parts - mainly the cam follower and Diverter Valve.

I heard Revision G of the Diverter Valve is the better unit but the dealer told me they stopped issuing those and are giving me a different part number - 06H 145 710 D. Just wondering if this is as good as the Rev G DV or should I consider shopping elsewhere for it? Any tips would be appreciated - thanks!

D is the older part number, G being the newer one. They are fobbing you off, probably trying to sell off their old stock.

I'd consider upgrading to a GFB DV+ rather than a G that will split again in time, or a D that leaks

I actually have a brand new G at home. Should really get round to advertising it as I went GFB DV+

@Dan_FR (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=9513) how much are you looking for it?

Isn't the Rev D the spring type valve and rev G went back to a better quality diaphragm?

Rev D can't split because it's a spring and not a diaphragm but some people believe it holds less boost although there's no studies to back this up.

If you're shelling out for a new one then just up the money and upgrade. If you don't care too much, opt for rev D.

I had a D, leaked boost from brand new, this was in a stage 2+ car, so guess it would be OK at standard boost. I run the GFP like Dan, much better design and will def hold all the boost you can throw at it !

D is the piston type, They do leak! Niki at R-Tech swears by the Rev G, I fitted the Rev G on 3 x TFSI's now with no issues.

The annoying thing is I had a load of work done by a mate who is a master tech at audi, gave him the part number of the Rev G, never thought to check till last week when I notice the boost was lower than expected. Turns out his parts department gave him a D as it was newer. So I had been running a D for a while !

Cheers all for the replies, I will have a look at the GFB DV+ instead. Anyone can recommend a good retailer for these?

Not to doubt you but from what I've seen, this is only hearsay. Not one study has been carried out swapping out a D for a G and measuring boost accurately across both.

You have a link to info? Genuinely interested as I've bought and fitted both and couldn't distinguish!

The last I read about those DV+ things is that they had some issues and leaked to from memory. This is going back a while. Take it they fixed what ever was wrong?

I changed a perfectly Rev G out of my Pirelli as soon as I bought it and fitted a GFB DV+, far superior in my opinion.

Just fit and forget and no boost leak  :happy2:

As long as you buy from a proper retailer, AMD, Awesome, Demon Tweaks, TSR etc. then you'll be fine.

All of the leaking issues were fixed 2-3 years ago with revised items. They now work as they should

As for the D vs. G thing, I have seen the data in the past in the form of boost logs and N75 logs, showing the turbo to be working harder to maintain the lever of boost. They don't all leak hugely, some are a lot better/worse than others.... but the very nature of the design means that it will inevitably leak

I'm off to rtech on 30th July and I know they check and replace if necessary the dv for rev g. Do rtech stock the dv+ aswell now. Cheers

No they don't stock them. You'd have to supply your own and check that they don't mind fitting it for you

I too fitted a GFB dv+ supplied by AMD as my original rev d was completely split. Boost comes in earlier and holds. Completely different car now.
