So I pick up the car last night and it looks like everything is working. I spoke with the SA and mechanic about what happened. It turns out that this was a very common problem. My original CCC unit malfunctioned. The first replacement unit they ordered had the exact same problem as my original malfunctioning one. The mechanic even thought he put the original back in by mistake. The second replacement unit finally worked. Supposedly, getting a ccc unit from BMW has been a crap shoot. It has been hit or miss whether the unit works straight from BMW.

So overall, not too bad of an experience. Only had my car in the shop for about 12 days.
