Hi Guys

Can you fit a Dump valve on a A3 1.8T (Standard)

What needs to be done .
I just want the car to make that Pssst Sound


Thanks

You can do it, BUT

a) you will lose turbo inertia between gears.
b.) You will confuse your N249 valve, and sometimes your ECU will assume a boost leak and cut your throttle response (sort of like limp mode effect).

Get a decent dv and if you want the psssshhhhh sound, rather buy a tape recorder

Hi,

I agree with Will....do not go there

Get a Bailey DV30. Direct replacement of the old Bosch unit, no servicing and a loud'ish diverting/dump sound Not as hard as a genuine BOV but VERY nice I've got one and I've convinced another Audi owner to also get one just because of the sound and reaction speed!

Hey Jaco where does one buy Baily DV 30 in SA from and what is the cost ??? I know it is straight forward install so if cheaper I would buy over the net I think around R1000 give or take which site is reliable quick delivery I remember when you Jaco mentioned you bought one but where from escapes me ????
Does anyone know if there is a different one for a Multitronic cars I was told automatics are different than manual valves ???? Can't see the logic but any advise welcome.

Buy a Forge one from us. You get a local warranty from us on it, it costs you less, and nobody, despite their wild protestations has been able to prove to me that the Bailey is any better. Mr Mayor? Yes it will work on your multitronic.

I've still got my GFB 1003 hybrid valve if you're interested (just taken it off my Multitronic since I changed it back to stock). Being a hybrid, you can set it to be a fully diverting valve or 50% blow-off. Shiny silver, perfect condition (hardly used), looking for R1000.00 if you're interested.

Well I might be interested 2 questions though.
Is it as easy to fit as the Baily one and does it actually make a difference in the Multitronic setup.Sorry to sound like that but if it does help why change it back surely it makes not diff to FWP it does more good than harm.

Hey.

My 2c on this thread;

1. After much reading around on VWVortex and Audiworld, in my opinion changing your DV on a non-modified vehicle doesn't buy you any more performance; only less uncertainty because the stock one is garbage (which, because it tends to go gradually, you will not really notice unless you're aware of it).
2. After market DV's all still require servicing, but far less frequently than the stock one
3. GFB is very well regarded (for an AU-made device)
4. Forge is also well regarded, and backed up very well by Will_20VT - springs, O-rings, grease, etc are obtainable easily from him

My opinion; buy the GFB if you want the whoosh, otherwise buy either the Forge (my recommendation) or the up-rated OEM DV (I think its from a 06A 145 710 H to a 06A 145 710 N), which you'll still have to keep checking.

Thanks Khetan helpfull as always
Yes I combed the Net last night and both Forge & GFB are well regarded I don't expect a performance gain and even the noice as the Multitronic gearbox doesn't have the change of gears gap (in D that is) therefor no noise I assume.
Mine is OEM and was replaced sometime last year with the MAF when I had major power loss. Bottom line is not expecting much just wondering as my car will be out of FWP by year end and as you said these things are like clogging cat converter they go gradualy and you only pick it up months down the line with proper DV (I think GFB is not servicable so is the Bailey) there is no issue.
Cheers.

I ran a GFB Hybrid on my S3 and would never run anything else on a 1.8T, that said, the Forge is a good DV, and Will offers great backup. And in the end - after sales service is more important than the extra few percent that the GFB is over the Forge.

The GFB sounds better though!

Well, I opted for the GFB since it seemed like the Forge also had one or two issues with diaphragms or springs (according to some websites, can't remember which now - I was researching this about a year ago ). However, they are easily replaceable and as the guys say, there shouldn't be any issues with after sales service from Will, so you should be in good hands! Also, at the time, I wasn't aware of any local sales agents for Forge / Bailey, so imported the GFB along with a friend who was doing the same. Swings and roundabouts...

The GFB is a great valve, nice and solid. It's easy enough to fit, but make sure you can put the car up on stands. The A4 has the DV at the bottom, just behind the radiator on the driver's side, I fitted and removed it with the car on a jack and supported with bricks so it's possible, but helluva uncomfortable and unnecessarily difficult that way. I just removed mine when I had the catalytic converter replaced - wanted everything stock to figure out why the power didn't seem right. Also had the chipping removed. Now just couldn't be bothered to refit it Now I just need to convince the guys to check the MAF. I was given a story that the MAF can't really be checked even by the dealer's machines, and that a known good one should be fitted to test it. Don't know about that story, but need less to say, the MAF has yet to be checked since there are never any 120kw 1.8T's available when I am...

Anyway, the valve is still available if anyone is interested. If not, I'll just refit it

Hi. I am interested in your DV. Please e-mail me direcly so I can get a little more information from you. I have a 2001 A4 B5 1.8T facelift and looking at something a little different. My e-mail is bradley.p@webmail.co.za.

Thanks

Well I am rather keen on one and have found tons of stuff on them on the net and web forums the question that remains unanswered is does it make a differance (sound / performance wise) on a Multitronic car.....are you coming to the AGM next Sunday if so bring it along I might take it off your hands.

If your car is stock, and your DV is in good working order, dont mess with it. If a car is looked after,sometimes even the stock Bosch jobby can give you over 150k trouble free.
Even if you dont buy it from me, rather buy a bailey before you go for a blow off or hybrid.
Those German VAG fellows with the bushy eyebrows knew what they were doing when they designed it to divert, when you bugger around with the way your engine diverts, you are introducing trouble. No jollerboy fresh from Illegal to Legal drags (no anaolgy to those on this post ) with a 96mm exhaust and tinted windows is going to convince me that atmospheric dump is anything more than a lot of..um...vented hot air!

Great point Will I sence a lot of truth in there.
Thanks mate

Vesco, much as I'd like to sell you my DV, to be honest it's a bit of a waste on Multronic. Without proper gear changing, I doubt the DV really gets much exercise. To be honest, I never tried it in "blow-off" mode, it was always in fully-recirculating mode, but didn't find it changed performance at all. The stock DV seems to be in perfect condition, so I guess I shouldn't have expected much - the blocked cat would have had far more of an influence. So my feeling is - on a multitronic, stick to a stock DV. For a manual, well, that's another story.

I had suspected something like that....thank you for your honesty truly appreciate it. Forge / Bailey and GFB are great products indeed but will only make a differance with the right application.
Cheers mate

I bought my Bailey DV30 from Demon-Tweeks in the UK.....worked out to about R1150 (all incl).

The reason I went for the Bailey is because I heard many stories about O ring failure, putting shims in and slow reaction during quick changes. I did not want any of the hassle and it seemed like Bailey didn't have any of these type of failures, setting or speed problems. You can do searches on VWVortex, Audiworld etc....

The above is just what I got through research on different sites.

There were no negative comments about the Bailey so I went for it. I must agree with Will that he does provide back-up service in SA whereas Bailey does not have an agent as far as I know. Bailey valves seems to last forever so I'm not worried and it is rated up to 4bar without setting anything!!!
