Edition 30 owners - how much hissing?

[_Nathan_]

As said really, if you drive along with the window down how much hissing can you hear when you depress the accelerator?

[Tfsi_Mike]

Standard - next to none
Standard with Forge spacer - lots
ITG inlet with forge spacer - lots and lots!

Also I found some time ago a vacuum hose split to my DV and that hissed alot...

HTH

Very useful thanks

Do you have one of these under your bonnet?

[_Nathan_]

You've made me scared to look now ;)

Very pronounced hissing.

[Tfsi_Mike]

Does it feel like there's a loss of boost or performance at all?

[Tfsi_Mike]

Goes to photobucket to dig out pic*

The soft rubber ones the same diameter as the tubes used for window washers.

[Tfsi_Mike]

Split diaphragm in the DV perhaps?

[_Nathan_]

Have already ordered another DV just in case, how common is it for Rev D valves to fail?

Thanks for pics, will go and have a look see.

[Tfsi_Mike]

The hoses in/out of the sensor in the top right of the pic too

Did the System too Rich at Idle  error code come back on whilst on Revo stock code? It sometimes would come on VCDS 2 days after the fault had actually occured when I checked after converting the Km to Miles.

Do you wan me to drive and confirm Nathan? 

[Hurdy]

I though rev d diverter was the piston type!

It wouldn't fail if it was a rev D DV

I haven't heard of any revD DV's going.

[Hedge]

I seem to remember Forge suggesting rev D's had failed.

Why not come down to JKM and stick it on the Dyno. At least you would have some idea if there is a problem or not.
