Brake light will not go out after resetting
 

Ok, just purchased an 08 MCS. When I bought it brake light was on. After inspecting it, found the rear brake sensor was sheared in two. Ok,no biggie. Bought a new rear sensor, installed it, went through the process of resetting the indicator with the BC button. It seems to be resetting (shows the little timer) BUT THE DANG LIGHT WONT TURN OFF! Ideas?
