Mazda MX5 1.8
when im going real slow in traffic or sommat (ie. low revs) i get an annoying knocking/clicking which appears to be coming from behind the dash
it goes away when i speed up and if i dip the clutch it goes away as well
doesnt sound like a rattle - sounds more mechanical.........
just wondering if its normal or if it needs to be investigated? - happened ever since ive had it iirc
