    1.9 tdi noise on acceleration

    I have a 1.9 tdi sport. Under acceleration, there is a deep low pitched bellow. It has recently had 12 months MOT put on it, so wouldn't be a blowing exhaust, plus it doesn't sound like a raspy exhaust blow. Would it be an intake hose loose somewhere along the line? Where would be best place to star looking?
    Thanks.

    I'd look at the air box seals, does it sound like air getting sucked in? Check the fulter too

    How loud is the noise?

    Yeah sounds like a deep air suck sound.
    Noise is quite noticeable from in the cabin. Quite loud.

    Like a grunt on initial foot down. More noticeable when you rev it up?

    Yeah. It bellows under acceleration. Foot to the floor or quick acceleration. Any ideas?

    If its not hesitating then it could be normal, check the air box as the grunt could be from the air mass meter. Open the air box and rev it up does it sound the same but louder?
