Did your car showed it in the CBS, you saw it?

It's a change at 37k unless CBS tells them something different. CBS told them to do my car between 42-44k. They said every new BMW except early X3s has CBS so I'm guessing some dealers just bend the rules a little if people are getting plugs at 37k regardless of what CBS is telling them
