    Whirring Noise

    Hi all
    98 tdi automatic, 100000k on the clock.
    At low revs - before the turbo comes on - I am hearing a low pitched whirring sound that goes wiith engine revs - seems to be more noticable when the engine is cold. The noise may still be there at higher revs but may be hidden by engine noise. I know this doesnt give people much to go on but thought it might be a known tdi thing. 8O :roll: :?:

    thanks
    Lindsay

    open the bonnet and try work out if the sound is coming fom under bonnet or under car...
    If under bonnet, try and locate offending part using a screwdriver as a stethascope....

    Hope that helps somewhat

    How long have you had the Disco? In other words is this a recent phenomenon?

    Some are quieter than others. A snorkelled Tdi disco will transmit more engine noise than a a non snorkelled for instance.

    whirring noise

    Thanks all for those hints
    I have only had the car for a few months.
    When I drove today I didnt hear the noise - it is intermitent 8O 8O
    To me - it sounds like an air noise.


    cheers

    Handbrake's tdi does the same. I reckon it's the alternator loading up after the initial big discharge hit on starting. Just a theory...
