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.

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?

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.

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(]

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 [:D]

"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?

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?

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.

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....
