is the new LCM from a Touring?
if not, that's your problem. BP helped me with this as i was trying to put my FW v4.5 LCM from my sedan into my Touring....and i got the rocket boosters.
if i remember correctly, BP read the FA from the instrument cluster (in the Touring) and copied it to the LCM, and then reset the LCM to factory defaults? we did this with NCSExpert.
i'm running on very little sleep lately so i can't really remember. it was something along those lines. hopefully he can chime in here.
