Managed to sort this . You need to pull the lower grill out to give you space and then on the outside edge of the light is a knuckle pivot for the aim adjuster to work and you push it towards the grill to un locate it. Then it should come out. Bloody fiddly job just to clean the lenses out. Look nice and silver and clean now. Now I know when i see cars with broken ones, why they dont want to change them !!
