    rubbing/grinding noise

    my 99 S3 has been well driven and serviced at the right time,it has now developed a new noise (best way of discribing it ) from the underside of the car.
    1. I thought something was hanging down ie. the undertray from the engine, Not that.
    2. The heat sheild on the cat , no I repaired that earlier this year, still nice and fixed.

    The problem is not there all of the time, without having a ramp to properley investigate, does anyone have any thoughts

    Have you looked at drive shafts for shiny bits were they have maybe been rubbing something.........Prop shaft bearing maybe knackered or the Prop cover has been hit and is hitting Prop

    Does the noise happen all the time or when you accelerate
