    Could be the turbo,quite alot of diesels make a whine noise,usually nothing to worry about.

    Might be something to check if its getting louder.I would defo first check all the small vacuum type pipes followed by the larger boost pipes.

    DOH!! ! !
    how gutted am I!,
    was on the way home tonight, minding my own business as usual,
    came off a roundabout, booted it (as you do)
    big pop and a bang followed by a total lack of power .
    into manual and coasted to a stop,

    After a long wait the Audi tech turned up and diagnosed either the turbo actuator or the turbo had let go :-(
    while waiting for the flatbed thought i would phone Audi and get a ball park cost,
    the deal is that you cant buy the actuator without a turbo, so its going to be nearly 2k! just to start !
    aragh! not what i need on a Thursday, just got in now after the long slow drive home on a flatbed
