well, I originally voted no as I haven't heard a thing but now I am hearing a faint pinging and my missus said to me the other day that with the window down it was rattling.

Then this morning a work mate said as I drove past him on the road yesterday that the Euro was rattling its head off. He's a mechanic so I asked him for more info on the sound and he just said ' sounded like it was pinging its head off'.

Oh well, thought I was a lucky one since it has done 20,000km.....
