probably a daft question but I cant find how to turn off service lights, obviously I am not looking in the right place. Could you tell me where to look, thanks
On the left hand side of the screen Click Trouble codes, it is the 3rd one up from the bottom.
Then at the top of that screen there is a "clear trouble codes" button. You may need to press the one to the left first labeled "read trouble codes". That should take care of it. If the light still doesn't go off it is probably a fault with the vehicle that needs to be fixed.
