    Just wondering has anyone ever experienced this or have they any idea of what may be causing it...

    I've noticed when I lift of the gas and the car is decelerating that I get a loud buzzing\humming noise from the front of the car on the passenger side.

    The noise always comes in when decelerating, and always at 35 MPH...by the time i reach 30MPH the noise is gone.

    The noise happens regardless of whether I'm in or out of gear.

    Any ideas?

    what car is it?
    s3/a3 quattro system can make a noise if tyre treads are diffent by a few mm, and also if the tyre pressures are out they would be the easyest things to check first

    Oopps...forgot to mention, it's a 1999 S3.

    The noise isn't coming from the tyres, as it is still there when she's up on the ramp.

    I recently got my suspension upgraded...bielstein, h&r 25mm, H&R arbs, Forge rear adjustable tie bars.

    I also changed the haldex oil and filter about three months ago.

    Any ideas anyone?

    alignment was done after lowering, everything spot on with that.
