chattering sound from 1.8t

[dwood]

well it could be turbo problems is there any extra smoke coming through the exhuast??? usally a sign somthing is up with turbo
if you have the black plastic dv i would suggest replacing this as they had a hell of a lot of problems with these id go for forge dv which i have ive had no problems with this at all ebay i got mine for £35 sqid

[AndyMitton]

ok...no appernt smoke coming from the exhaust. not really checked a great deal, but nothing that i have seen. i think il change the DV, if that doesn't cure it, ill take it back. just the place is 80miles away, and wether they'll be able to do it on the day etc. etc. Thanks

[dwood]

[AndyMitton]

The rattling sound just seems like something is loose.. trust me you'd know if it was your turbo internals rattling around. It may even be the heat shield on the cat, one broken weld and it rattles around.
I'd ring the garage first and make sure they have the proper diagnostic machines on site to check for faults.

A lot of faults that show up on vagcom won't give you a dash warning light.

thanks mate...gonna say, nakered compressor fins would cause a hell of a racket and wouldnt be functioning. they dont have it, but can outsource if i bring it there. i did have the engine top cover off last night, so could be that. time for some gaffer tape

[AndyMitton]

well i got hold of an oem valve, fitting this evening. that rattle seems to be loose cat cover or something along those lines. Also, could this valve malfunctioning cause a drop in power or increased lag? Thanks

[AndyMitton]

Took 5 mins to fit the valve. All is fine. Thanks

if you are after propper chatter like a cossie then no you wont get it, to do this you can block the dump valve and get an induction kit, but then preppare to order a new turbo as the little fella wont take buch of that, that noise happens when the air goes back through the blades of the turbo, again not good for the little fella,

just stick with the wwhhhoooosssshhhhh, or buy a cossie for the chatter.

hope that helps.

Thanks...i was actually tring to get rid of the flutter sound...changed the DV for a new bosch one...the hoses already had jubilee clips so i guess its been done before.  the DV i removed resonated when tapped, lkike a pringy feeling, suggesting the diaphragm was shot. put the new one one...literally 5mins...SOLVED! excellent. can hear i lil woosh into the air box if u listen hard. Cold air kit and itll sound mint! Picks up a lot better too now...VW wanted to charge me 60+VAT for the valve...WTF...and the its 95+vat for labour!! WTF! thats ni on £200 for the job. cost me 20 off ebay. glad ive got my head screwed on. only take my car to the garage if its my last hope!lol Thanks, Andy
