Probably a headlight level sensor has failed or the link bar has broken.

A link bar breaking "front or rear" is a very common problem, and due to the ball joints at either end of the links seizing. It is easy to repair these either by replacing with a threaded rod, and new ball joints readily available on eBay. Or by simply fitting a suitable piece of tube over the broken stubs fixing them with hot melt glue or epoxy resin. 
The warning light not coming on or staying on, and an obvious broken link is an MOT failure now. This is because the headlamps are HID, and require levelers to help remove glare to oncoming drivers.
