A common rattle on the Scirocco was the bump stops. Check both stick out the same number of notches. If not, stick a small (was it a 1.5mm/2mm?) allen key through the centre of the shorter bump stop, slacken it off and pull the bump stop out until it has the same number of notches as the other side and tighten allen screw again.
