Hi everyone,
Long time follower, first time poster...
I'm completely new to coding so please bear with me!
Part 1: I had water damage from a badly installed windshield.
Part 2: I replaced the water damaged junction box and JBE from a 2011 LCI e93 donor car.
Part 3: I bought a K+Dcan cable and got a guy online to try and reprogram the JBE
Part 4: He did turn off my airbag light and seat belt light, but I'm still missing the following functions from my 2009 E93.
Rear windows, power locks, trunk release, auto lights, convertible top and sos function.

Is there a place I can start to figure out what software I'm missing and how to install it? Believe me, I understand this is a tall order, but I'm jammed. And, appreciate a place to start!
