hi guys .. got my 1.8T last week,wel happy etc .. but i noticed summin, when i come off accelerator .. it makes this sort of dump valve noise ?? like a thhrrrrrr noise.. > gettin a little worried now.

now i know these 1.8T golfs dont come as standard with dump valves etc .. so what could it be ?? coz i drove one in london .. and this didnt make a sound at all when i came off the accelerator ???

any ideas and cures please ???

Diverter valve is prob worn out mate []

Is it chattering when lifting off or changing gear if so ya d.v is on it's way out. Mines doing the same at the mo.

If you've got a fluttering noise your DV is already dead as the fluttering noise is the turbo stalling.

Wouldn't you have lack of power/not getting full boost??

You will get full boost but spin up time (lag) will increase.

 

[Royster]

No because the turbo is fine but without boost being recirced the turbo stalls and takes 2-3times longer to get on boost unlike normal!

D'oh! beat me to it Paul![]

You've both got me thinking.. It does feel as though there's a wee bit of turbo lag [V]. It doesn't feel as lively as it use to.

Hmmm where's that credit card? Where can I get a DV tomorrow

 

[Andrew]

You can get the standard vw one from vw or audi but you might as well if possible replace it with a Forge one. My standard dv has just gone and I will be getting a Forge DV. As for tomorrow, not sure if anywhere that sells them will be open.

try getting in contact with simon coe from upsolute he will have one if you live near him you will be in luck

Hi there...I used to have an A3 1.8T and Audi replaced the bosch DV that was fitted when it started making a whoosh noise...I have now got a GTi (2001) with and it feels a lot crisper in acceleration but it makes the noise when I let off or change gear...is it supposed to make any noise at all? I thought it was odd but I only got it from VW 2 weeks ago so figured it was okay!

 

[Royster]

It should make a soft psssss noise. instead of pfpfpfpfpf(hannibal lector impression).

To be honest with you the stock DV is more than adequate unless you're going down the big performance route but as you can see they do fail quite often.

 

[tyler durden]

Thanks for the info...I'll check the noise tomorrow and if it sounds the least bit Lecter I'll take it back to the garage!

 

[Vinny ZS]

thanks alot guys for your input ... knew you lot would have the answer .. question now is how much are they from VW ??? and should i fit it myself ?? or get it booked it ??? how much will it cost to get it done from VW ???

and theres me thinking i had somethin special when i heard that noise lol ... so much for that eh ...

 

[Royster]

LOL! fitting is quite easy. The most tricky bit is removing hose clips! They should be circa ?30-50 but I can't quite remember

 

[Vinny ZS]

nice one mate cheers .. any one got any pictures of how to change it at all ..

 

[Royster]

Clicky but no pics

 

[Vinny ZS]
