My manual seems to indicate that my 1.5tsi petrol Technology has interior courtesy lights but I am damned if I can get them to function. Reading lights... Yes. Go off and on with ignition but an interior light that comes on when you open a door and goes off when you get in or start the car... NO! I've tried all switch combinations (I think) to no avail. Help appreciated. Footwell lights are on. Crazy.

Its the button with a picture of a car with the door open. It should be pressed in to be on.
