running TOTALLY stock 2001 1.8t 20V......

normally i cant really hear my DV, just a quiet deep breath kinda sound on the gear change......

BUT, as of last night......

it has started making a louder psssht kinda sound, and a chirping sound, almost waste gate like......

but i aint even reversed the DV......TOTALLY standard......

and it smells a bit too when i stop the car......

any ideas??

IMO, hte chirping means it's on it's way out. IIRC, the chirping is the diaphragm inside ripped so it's not holding the pressure correctly. Anyone correct me if i'm wrong.

YOur bang on the money mate. It flip'D

Mate, I had exactly the same problem start on my 2001 stock 1.8t last night too! Was giving it a shoeful and things started making noises that sounded wrong, except mine started to judder on acceleration aswell, that went away though. I guess it would be worth going for a Forge DV if its got to be replaced anyway?

 

[turbo paul]

yep its definately broken if you can hear it. You can either replace it with another stock one around ?25 iirc or you could get a direct replacement forge dv. the forge one would be useful if you are planning a remap because stock dvs seem to brake quite often when run on high boost.

 

[Essex Escy]

so we saying its bust?

how much for a forge direct replacement??

will i damage it running it?

will it be covered under warranty?

 

[turbo paul]

yes

about ?90 iirc

nope but car will probably feel a bit sluggish

i have no idea but hopefully!

 

[Essex Escy]

with a "direct replacement" DV from forge, do you get added sound?

 

[tylerama]

Nope .. if it's a recirculating job, it should be quiet. If it's an atmospheric one, you'll get the Psssssstt noise when it vents to atmosphere. But, supposedly the non recirc ones are not a good idea with golfs.. but I think the jury may still be out on that one. Do a search on here for more information.

Ive had this 3 times in a few weeks. Took it to vw specialist who diagnosed nothing wrong.. apart from it being noisy. has happened once since, doesnt last long though and jut gradually comes back. Keep us up to date if you replace and its problem solved..?!

Cheers

Sounds like a problem a mate of mine had with his T reg 1.8T. Had the fluttering sound.. took it to the garage (VW dealers) and they said there was "something loose" in the turbo.. didn't diagnose a knackered DV of course ! [xx(]

 

[Essex Escy]

well i called the stealers........they reckon theres nothing "wrong", and its the DV, but some people leave it like it apparently......

but aint i loosing boost??

 

[turbo paul]

yes i think you are losing boost mate. when mine was broken the car was real sluggish and i noticed a big improvement when my replacement was fitted.

btw as your car is dbw you can not run a bov. the only way to get noise is to buy a cai. they sound nice []

 

[Essex Escy]

"DBW" ??????????????? whats that mean mate??

it dont feel THAT sluggish, infact, i aint really noticed any difference...

last night i spoke to a skoda mechanic, bearing in mind the 1.8t engine is the same as the skoda RS....

he says that its causing no problems, nor loosing power (though deep down i think it is) he said its doing the same job, but with noise, and also said, that one of the mechanics takes the "faulty" DV offthe cars, replaces them, but then sells the "faulty" ones to people who like the noise....

so could i be lucky here and have a "positive" fault??

or is all this rubbish and its bust?

 

[Milkfloat]

I would not bother buying a forge, the standard ones are now uprated from when you bought the car and are unlikely to fail again. Surely if the diaphragm is split, you must be losing boost?

 

[turbo paul]

yes you will be losing boost as it is not being recirculated properly. the noise you can hear is boost escaping from the valve.

dbw = drive by wire = you dont have a throttle cable.

 

[Essex Escy]

cheeers buddy.....

good advice from all.......

the stealers reckon it aint detrimental to the performance,,,,,but as you say, if it aint recircing properly, boost must be down....

they want ?114 to replace it....

 

[Gti Fly]

?114 to replace what??

a new VW dv only costs around ?20! add to that a few jubilee clips (less than a ?1 in total) and maybe 15 mins labour to fit it.

What's costing ?114?

 

[Essex Escy]

the part is ?56 apparently, and i saw that on the screen......unless they got the wrong part of course, then labour to fit it......

 

[Gti Fly]

What was the name of the guy you saw?

Joe King?
