Has anyone ever had problems with coding? Any features that work before but not work after coding?

I have a late January 2012 build, actually just finished on January 25th and is shipping to the dealer.

I would really like to have the mirrors close on lock, idrive disclaimer removal, trunk raise and lower with key fob.

Now, how can the mhud be calibrated?

Just ordered the cable but a little worried, seems a little hackish.
