Odd Horn Behavior

[bmwgal]

Looking for some help from you guys, 2002 X5 3.0i Sport. Intermitantly when turning the steering wheel either left or right the horn will sound briefly on its own. Or sometimes it will honk just when I hit a slight bump. Occasionally it will sound for a few seconds straight. It has been happening more and more recently, I have just pulled the fuse because it is really uncomfortable in a parking lot as you could imagine.
Any ideas, thanks in advance.

Sounds like a short either in your steering wheel or the steering column.
