All,
Well took it back to the dealers and they had no idea what this is. It looks like some kind of antenna to me and the company who retrofitted some components for me in the past, said it may be an old Bluetooth component (I currently have the Bury Bluetooth kit installed), as Charlie raised...
I have tucked it down at the bottom of the windscreen - I have tested the wiper and light sensors and they seem "ok" - not overly impressed with the sensitivity of the wiper sensors though compared with my other cars.....
