I installed the LCI LED taillights last Saturday (see this thread for more info: http://www.m3post.com/forums/showthread.php?t=386823
) on my '08 E92. I had a new footwell module installed (necessary on '08's & '09s) and everything coded to work properly at Boyd Motor Werks in Portland. Despite not working too much on the latest generation BMWs, they used their Autologic system to eliminate the bulb check errors and code the module.
I recommend them if you are considering this upgrade. Talk to Eric. http://boydmotorwerks.com/
