That's probably because it disengaged. When the system is disengaged, the lines are gray (speaking from an LCI G30 btw).
I too suspect that your wheel touch sensor is broken. However, before going around replacing it, I'd rather open up the connections and reseat them just to be sure first. Go to BMW Techinfo and look around the diagrams to see how you can go about doing this, as well as other docs that might help you diagnose this.
