    Had my 2.0 tdi bdk 2004 a3 for about 3 months now. I always drive it with the radio on so tend not to hear any strange noises.
    Wife turned it off the other day and when i put my foot down to about 2000/2500 revs and either take my foot off the pedal or change gear i can hear a whooshing noise.

    I am guessing this might be the turbo? Or could it be a boost leak? Or even a hole in the exhaust?

    Or hear is hoping that it is supposed to do that :)

    Thanks

    Unless you're down on power, its just the turbo, check all IC piping makes sure its all secure, but I reckon its just that.

    It's the turbo. Mine is really loud, sounds like I have an aftermarket dump valve on. I have the 140 tdi too

    They do make that noise naturally anyway, but you get so used to it that it becomes everyday normality, stripped/fitted/cleaned a few & they all have some normal noises anyway.
