And just to be clear since I found contradictory information while researching, this does NOT need to be coded, it was straight plug and play. I've seen some threads claim they need to be coded, but I think those people are referring to the actual body module. The passive go module near the tail lights seems to act as only an antenna.

Rallim you are right in that it is plug and play and will work, BUT, there are issues if you don't code the module. The lack of coding may cause various modules to stay "awake" longer than necessary and thus drain the battery quicker/shorten its life. See reply in below thread from a BMW Master Tech, who recommends you get the module coded:

I had a similar issue with water somehow getting into the module (still have no idea how, but I suspect the body shop left my car outside while re-paining the bumper and water got in from the rain). I have a replacement on the way from ebay and plan to try and have it coded.
