Thought i would mention this in case anyone else has the same problem, as I know at least 5 people with same thing! It sound like a vibrating panel from the front end ( i first thought it was a ill fitting bonnet or loose bumper!). It turned out to be the screenwash filler neck vibrating against the airfilter tube. (if thats what its called?) I ended up placing some sponge between the two and attaching a lage zippy strap though an already available hole in the front panel (see attached pic). Now i have no annoying vibrating noise and it cost me no cash at all! Oh I trimmed the zippy strap off after taking the pic!
