it is probably the prongs on the circular knob that may have broken off... it is sort of like a "T" where when you turn the knob the top edges of the "T" turn left and right to depress buttons on the printed circuit board... I don't think BMW sells this part separately as I just looked on and couldn't find it to show you.
