    Default strange turbo noise

    ok guys so i posted a while ago about a Brrrr noise when accelerating, i couldnt find the thread so heres this one.

    i recently fitted a new airfilter and this has made the noise louder after i thought the boost sensor being loose caused the problem, apparantly not!
    i managed to get a little bit of audio from within the car of this noise but its in "amr audio" format and im not sure how to upload this? does anyone have any idea and this might help you identify the issue?
    i thought it only done it in second but its not, its in everygear when flooring it.

    When I had a weird noise coming from my turbo, the first thing that I did was check the condition of hoses, looking for any splits or damage where air could be escaping. After that I checked the turbo its self, I took off the air inlet from the air cleaner and checked the shaft for any movement. If there is movement in the shaft then the chances are that the turbo is knackered, which was the case with my turbo. This is a link to my thread.

    Are you sure the new airfilter is seated correctly and the airbox is sealed?

    2nd- http://www.zshare.net/download/68331685b6900b0b/

    3rd today(http://www.zshare.net/download/683317116a2c6dfb/

    i noticed the hard plastic pipe that connects to the flexi pipe for the air flow sensor doesnt have a bolt holding it against the engine, its away from the bolt by about an inch outwards. dunno if that matters though..

    let me know ur thoughts guys, oh and i think its realtime these files use..

    ok guys update,
    went out to the car today, put on the ignition and then it started beeping and the speedo started going up and down?
    done this for about 30 seconds, turned it off tried again and it done the same thing, then tried again and it didnt beep but the speedo went to 20mph a few times and stopped..

    so i started the car, reveres out and waited for another car to move, i then went to pull away and their was a plume of smoke (greyish blue i think).
    never seen this before!
    my abs light has also come on and stayed on over the last 2 days aswell.
    its booked in for the garage tomorrow because i give up!
    any ideas?

    i tried jacking the car up and looking under but had to take the mud gaurd off, so once that was done nothing appeared to be wrong..
    some oil round the intake side of the turbo but nothing off or anything..
