What DV are you running?

[airbornerifleman]

My DV finally gave in after 55K. P2099 code and less boost.

My car is an early 2006, so I believe it's the REV "C" (electronically operated with rubber diaphragm). I will be changing my DV with a REV "G"(electronically operated with rubber diaphragm) and not the newest REV "D" (piston operated). I have reason to believe that the REV "G" although still has a rubber diaphragm, is an improvement from the REV "C". I have read forums, where guys claim they are running The REV "G" DV with KO4s and even BTs, without issues. I also read that the REV "D" DV reacts slower compared to the earlier 2 REVs, due to the fact that it is piston operated thus requiring more pressure before it opens up. I would like to know what type of DV members are running.
COMMENTS WELCOME

My question to you:

1. DV (OEM REV "D", AWE..)
2. MILAGE ON DV (00000K)
3. CHIP (REVO, APR 91, APR 93...)
4. PERFORMANCE MODS (TP, HFC, HPFP...)
5. DRIVING HABBET (AGRESSIVE, MODERATE or MILD)
6 PEAK AND HOLD BOST (20PSI-18PSI)

[airbornerifleman]

-OEM REV "C"
-50K
-APR 91(primary),93,100
-Custom intake pipe and K&N air filter (not a performance mod, but I thought I'd through it out there)
-Moderate
-18PSI-15PSI

1. Rev. D - Just swapped out my "C" and I can attest to the boost spooling slower. I'm regretting it now, luckily though I still have the "C" version incase I decide to go back.
2. 45,XXXk on "C" 500 or so on "D"
3. APR 91/93/100
4. N/A
5. Very aggressive driving style, getting on it every chance I get :)
6 No boost gauge :(

With the "C" Revision I was getting a strange "Wooshing" sound that slowly developed since getting the car chipped (Was not present when i purchased the car) It had me worried that it was torn, but in fact it wasn't. Now my acceleration is a tad bit slower on the "D" and its disappointing.

Over 50 views and only 1 reply! wow. Maybe I should have posted a pic, lol. Sometimes I think the board is for posting pics and falming people. I am trying to create an informative thread, to help me and a lot of other members on here.

If members post up their info, it will help people decide which DV would be best for their individuals application. Come on AZ peeps, stop being so lazy. Every single member with a 2.0T engine should be participating in this thread.

here I'l post some pics

i'm running a 2010 A4 DV and going strong. car has 65k (new DV has been in for about 20K)

[brucebanner]

hey guys, im gonna get chipped soon, however my dv did go out on its own about 2,3 weeks ago, it was replaced by audi under warranty. how can i figure out what rev it is. and do you think since that its new and only 2 weeks old ill be able to run whatever it is with APR chip for a while, or should i replace it right away?

[SEXICÄN]

give me your VIN, i'll tell you

[yycools]

OP, there is no point upgrading to the Rev G when the B8 piston DV is available at the same price ($79). When I chipped my car (REVO 93), the tech told me the DV is hold, but throwing a code, so I opted to install the piston DV, so far, after 2k of mixed driving, no issues.

If you have a just replaced the DV, chances are you're running on the Rev G, which is better. I wouldn't waste money on a new piston DV. Wait until the OEM goes out and upgrade to the OEM piston DV. When you chip your car, the tech will be able to tell you if the DV is holding boost. I'd say you're good for at least 10-20k miles even on a chipped car before the new DV wears out.

[brucebanner]

give me your VIN, i'll tell you

but can you tell from my vin? do you think they put the exact same one in, or a diff rev or anytihng when i just got it replaced? i guess i could just call them and ask, they prob have record of it.

can anyone else verify this? i just bought the Rev. D, chipping the car soon, so i may hold off on replacing my oem dv after getting chipped.

Did you feel any difference in the low RPM range and the time it take to build and release boost between the DV that came with you car vice the REV "D" piston one?

[beantown]

give me your VIN, i'll tell you

You're able to see specific part numbers with a VIN?

[MCT9891]

I'm running the "d" revision DV, works great at stage 2.

[A42S4]

subscribed.. i've been chiped APR for coming up 2 years now and still doing fine on OEM DV.

Because the D valve is slower from off-to-on-boost than the G valve, and the G valve diaphragm is stronger than the C valve (the C valve was on my car for 25K of chipped miles without issues) and performs better and if not equal to the D valve.

Price is not my concern. Newest doesn't always mean the greatest. I would rather change my G valve every 25-50K than put a D valve on. The G valve will allow for the most optimum performance as an OEM part. Most ppl opt for the D valve because they are the newest, they don’t break, and chances are it will last longer than all previous revisions, but that doesn’t mean it’s the best performing. Plus the D valve is for TSIs and our cars are FSIs.

I do not agree with last sentence since my dealer replaced my old DV with the new piston one. So it must be the new Audi approved DV for both FSI and TSI.

But I really can't tell how my new DV perform compared to the old one. I do not have a boost gauge...

[QUATTROA4B7]

1. Forge switchable dv (on dv setting)
2. Around 8K
3. APR StgII+
4. Carbonio, TP, AWE exhaust, APR HPFP,
5. Agressive (when I can be)
6. I wish I knew, I need to get a podi.

The only other DV I ever felt was my stock one, and my
valve on the 50/50 setting. Obviously the 50/50 setting
gave some lag and the car didn't run as well, but
once I put it on the DV setting the car ran perfect.
I would say the forge DV is much better than my
stock DV was.

P.S. I have no idea which OEM DV it was, I bought my car
C.P.O. February of last year, I doubt the DV was ever replaced.

[inphamous_A4]

1. Rev D piston dv
2. 10k+ on the DV
3. APR stage 1 91oct.
4. Moderate driving habbits. i got 113km on mine
5. No boost gauge to check PSI

p.s airbornrifle who did your clear corner on your car ??

[brucebanner]

i called the dealer and he told me im running rev d, and it was just installed two weeks ago when my old one failed. should this be good enough to run apr stage 1 im getting done tomorrow since its brand new?

[QUATTROA4B7]

Yes, as they said above rev D is the newest and said to be the strongest but isn't necessarily the best for performance and quick turbo spool.

[elwigglero]

1. Rev D piston dv
2. 8k on the DV
3. APR Stage 2+
4. HFC/Milltek exhaust, APR 93 tune, APR hpfp
5. Moderate driving. 35k miles
6. No boost gauge

I noticed zero difference between the two DV's. I replaced my original shortly after I got the APR re-flash before it failed.

[JRMSLINEA4]

D/V in signature with mods. 10K on no issues. Driving habit?
Well I made it down the 1/4 mile in 13.74 seconds.
I'd say it's working ok.

[airbornerifleman]

1. Rev D piston dv

I did it myself with help from a friend.

[WalkerT]

Forge DV
24k
apr stage 2
tp, intake, AWE FMIC
No gauge (in the mail)

It works alot better than my OEM and my OEM was in great shape when I pulled it last month. Forge has a more positive "on ~ off" feel holds power longer than my OEM one did.


Update : 2013 Still running the Forge and never have an issue. Holds 24psi and I am running the 25psi spring with one shim. Works great.

APR stage 2+ AWE boost gauge ~ rest you can see in sig

I have to agree to disagree. Audi only chose the D piston DV because it won’t break, which makes it the most cost effective. The G DV still performs better than the D valve, but because its rubber diaphragm based it has the tendency to tear or break quicker, making it a financial and administrative burden on Audi. The D valve was a quick and solid solution for Audis bottom line.

The same could be said about Audis engine management system. Just because Audi programmed the ECU to output 200HP doesn't mean it’s the "best". Otherwise no would get their ECU remapped (chipped). The ECU is programmed according to emissions regulations and to ensure there is no catastrophic failure during the factory warranty period. You think Audi doesn’t know that our 2.0T can output almost 250HP with just a remap? Ask yourself, "why doesn't Audi send our B7s 2.0T out of the factory with 250HP"?

[Tanner]

The G DV still performs better than the D valve...

What's your proof that the G DV with the diaphragm is better than the D valve? I believe one of the tuners did some logging with the vagcom between the two and there was absolutely no difference in the measurements.

[davis449]

1. Forge
2. 30K
3. APR
4. See Signature
5. Aggressive
6. No Gauge

I am basing my statement on common sense and testimonials from vortex, fourtitude , myfastgti.... Until I get my REV G valve this weekend.
Post the "log" you mention of.

[Tanner]

That tuner I think was APR, or it was one of the well known ones if it wasn't APR.

[scoobycarolan]

EVOms vacuum operated, no electronic BS DV for almost 15000 hard miles. Apr 93. No issues.

[airbornerifleman]

i called the dealer and he told me im running rev d, and it was just installed two weeks ago when my old one failed. should this be good enough to run apr stage 1 im getting done tomorrow since its brand new?

Yes.

[af1master692]

where can i purchase a Rev "G" diverter valve from?

[CleverA4Name]

1. Forge DV
2. Less than 2000 miles since install
3. REVO ECU Reflash
4. No other performance mods
5. Moderately Aggressive
6. 18 PSI

I live in Denver also, 5280miles above sea level, if that changes anything.

[airbornerifleman]

where can i purchase a Rev "G" diverter valve from?

Online or VW.

[airbornerifleman]

UPDATE:
I have been running the "G" DV on my APR 91/93 with out any issues for 25000KM.

[AudiTFSI3o3]

1. Forge DV
2. < 5000k
3. APR 91
4. Signature
5. Moderate, Mild
6. Peak 19, hold 15

[AudiTFSI3o3]

Just an FYI

Forge DV = mechanical
OEM Revisions = electrical

[SEXICÄN]

Just run the latest rev DV and you'll be fine....

If you want a billet or different colored one, then buy one...

[davis449]

I have a Forge DV, had it for 20K miles give or take. Mods are in my sig and my driving style is usually pretty aggressive.

[oneovdabestyet]

just get this one 06H 145 710 D.... through all my research when i installed mine, the forge and all that shit is dumb because it doesnt last the new one has no rubber and helps with the boost. swap out your PCV valve for shits and giggles while your at it, and do the install yourself, way to easy of a job to be charged $120 per hour labor.
