Not the lovely whinge i'm used to... still makes that... but today, it makes.. a weird ticking sound.

Kind of like a sewing machine... which gets faster and louder as the boost rises. Its chipped, and starts getting pretty loud aroiund .9bar to 1.2.

I have no idea about these sort of things... could this have anything to do with the loose turbo bolts post??? i really hope it is, cause its a cheap simple, and warrenty fix.

Mate thinks possibly a bend fin... which i guess wouldn't be cheap, simple or warrenty.

Any others experience with this sound?

I might be able to record it, shed some more light... but for the time being i'm going to stay off boost. hope it goes away or summin.

Ideas?

edit: only guessing its turbo due to the fact it gets louder with boost, i guess it could be anything. Its not really that noticeable in 4th or above.
