Unusual knocking noise, S212

[mattc]

A bit stumped here.

We have a knocking noise underneath when I come off the gas and coast. As soon as I brake it disappears. We've had the car on a ramp, checked everything underneath and cannot find play in any of the usual suspects.

The car drives perfectly, changes exactly as usual I cannot feel anything through the pedals; just the knocking when I come off the gas. Any thoughts/experiences??

Cheers.

Hi mattc, it could be the bushes on the anti roll bar are worn

Should have posted earlier. I found the problem. A loose wheel nut was making the noise!!
