Hello Slidge,welcome to the forum.
It sounds to me as though this is a button that someone has put in themselves.It could be for an alarm system,auxillary drive lamps or a 'home made' immobiliser.Also,has it got a towbar with twin electrics?.Could be something to do with that if it's fiited.
Some of our other members may have more ideas.
I'd rather push my Alfa than drive a BMW....
