Dump Valves

Ah right, was gonna say, it was OK. sounds like the DV has now failed. Has the power dropped off then??

Si, a std car should not make a chattering noise. Suspect the DV if it does.

Agree - there is a failure scenario for the DV where it can cause that chattery noise from turbo stall (cos the air has nowhere to go between gear changes)

Power doesn't appear to have dropped - it's still boosting over 25 psi.

Again apologies to Pete_RS2 but again, for both of us I suspect.....

Thanks Tom, that therefore leads to the following question....What is the difference (except price) between the following?

OE S3 DV £15.41 (VAGparts)
OE S2 DV £23.70 (VAGparts)
FMCL006 £80.50 (forgemotorsport.co.uk) piston?
FMCL007P £80.50 (forgemotorsport.co.uk)

£8.29 on the Audi ones :mischeif:
and search the forum on the Forge types
I use a hyperboost from milltek

[ThatGUY]

So chattering is bad?
Is this only on stock setup?

I use a hyperboost from milltek

Me too no probs so far and it looks well nice. Still not moved it into view yet though

Tried a forge FMCL006 last year, had loads of bother with it, Piston kept sticking. (I tried it both ways round too)
Forge were about as helpfull as a poke in the eye.
It now resides in a field just south of durham on the A1

The horn noise... I thought it was normal :/

do u get a get a vibration at the same time?

guess i need a new DV

[Ski]

is the stock DV bad? why everyone moving onto forge etc... what is the advantage?

[alg]

Forge for longevity against cost piston type not as quick acting
Standard diaphragm for cheap quicker than piston against do not last

Forge I believe have come up with a diaphragm model which may be the answer

does that mean the standard DV is quicker but dosnt last as long?

[HPmuirt]

No definitive answer yet, but so far I have gleaned that the piston type only offers longevity over the diaphram type, but quite franky, it would have to last for 30 years to justify the cost over an OE diaphram type.

So what is the difference between the OE and the TT/S3 DV please
