I'm not sure if it'll need a new wiring harness and/or LCM, but it will likely need a new software flash. Any competent shop should be able to do this for you. I replaced my pre-LCI E92 taillight assemblies with LCI E92 taillights, and I did need a new harness (BMW part) and a flash, which I got from a non-BMW shop (EAS).
Yep sorry that what what I was hoping to do
buy the whole light assembly.. thats the easy part.
After that I don't know what to do re wiring harness and LCM as BMW tell me my VIN has no retrofit available hence they cant sell me parts that dont exisit for my car..
