Ok good,just as i thougt.....ill leave the light alone then:)

Mine does it too, i had to rebolt the heatshield to the cat before so I expect it is the heatshield above the cat in the tunnel on mine making a noise, must try and have a look sometime.I only notice it with the window open and low revs so it gets forgotten in the winter!
