Quick question is a diverter valve the same as a dump valve? just different names? Every one on this site just refers to dv.

I need to know becasuse the common chi chi chi rally car type noise is comming from that area when letting of the throttle.

I am just going to fit a new VW "stealer" part. Any ideas on the part no?

Any info would be great.

Diverter valve does what it says and puts the air back into the system. a dump valve generally dumps to atmosphere with the cool tishhh sound.

If you've a 150 Turbo try and get the 180bhp valve as thats a little stronger.

Id say get a forge one, DV007.

It wont let you down like the VAG ones and will hold alot more boost, my cars boosting at 22psi and i use the forge dv and its never let me down.

Leave the VAG ones alone. It will only need changing again in the future, where the Forge ones can easily be serviced/cleaned

are they hard to fit?? im only asking cos my mate has just vag com'd his 1.8T and it has come up with the diverter faulty code.... i searched for it and found that ppl seem to change/upgrade them quite often..

is it a case of "another" common problem to look out for with the mk4??!!!

any pics/description of the location of the DV would be much appreciated, we're gonna change it soon..

cheers for the help tho' HardeepG...just a quick question...what was the part No. for yours (and is yours a 1.8T...150??)

Hi, mines a 1.8T 150 and i fitted a 06A 145 710N. They are easy to fit, take off three clips (or break em off) holding the d/v onto the hoses, and then refit using new hose clips! easy. i've heard the RS6 d/v will also fit but its a bit more pricey - loads better on a re-mapped car..part number 06A 145 710P. For pics see http://www.uk-mkivs.net/forums/thread/300520.aspx The dump valve is at the back of the engine, just behind the cover in the centre to right hand side if you are looking into the bonnet, a little round black thing with 3 hoses going into it, one from the side, one from underneath and a thin one on top. Hope this helps

What colour spring do you have on your DV ?

Would it make a difference having a standard green spring on your DV putting out 22PSI?

Only reason i'm asking is that i've just got mine chipped and have a forge DV with green spring.

I have a Forge 007P Diverter Valve complete with D/V Tuning kit for
sale if anyone`s interested. Only been on the car for about 1
month and is still in `as new' condition and boxed.

I now have a turbosmart dualport valve fitted so no longer need the forge.

Regarding the springs, I had to replace the standard green spring with
the yellow spring, due to boost leak, but some people have no problems
with the green spring fitted. All depends on what mods you`ve
done I think, trial an error.

i have the forge eliminator one fitted to mine
it works great and it does seem smoother but now i fancy a louder one
after hearing one on a mk4 the other day but i heard lots of bad things
about the atmospheric ones
I have the Turbosmart DualPort dump valve fitted now and it`s
great. It`s given me no problems, works great and no error codes
have developed since fitting it. Oh, and sounds very nice, not
too chav.

This dump valve dumps back into the system and also to the atmosphere.

If you`re near Gloucestershire anytime then I could take you out in my car as it`s an AGU.

I have a Forge DV 007 fitted to my AGU 1.8t and not only was it a 5 minute job but it is a superb replacement. The standard VW one often fails as it is not a quality item. There is no 'whoosh' with this either but if you listen you can hear it diverting pressure into the airbox when you drop the clutch.
