    sound like a boost leak to me. check all your boost hoses and look for cracks.

    I think its possible for sure, mine certainly seems louder at 6am in the cold winter air!

    perhaps its just because the rest of the world is so quiet at such an ungodly hour?

    Recently mine has been sounding like airplane landing gear. That noise when the landing gear goes up/down, thats what my turbo sounds like.

    I hope its not knacked...

    Mine (different car, similar engine) whistles louder in the cold. Should get even louder and more consistant with a FMIC & TIP fitted.

    Well thats what I build test and develop for a living so even if that sound isnt pleasent its better than the sounds of people screaming as the plane skids off the runway... If your turbo sounds like that THEN your in trouble. Trust.

    My turbo sounds sexual :)
