Recently i managed to install this BMW ICOM Rheingold 3.50.32 software to my laptop and connect it to my E90 320d using INPA K+DCAN cable. It is very good software to troubleshoot, diagnose fault, coding, workshop manual and register new battery with step by step guides. if not mistaken, BMW service centers and dealers also using this software.
it took me about two weeks to install and figure out how to connect to my car. here I share back the step by step guides how to install it for our benefit also for my future reference.

To connect to E90, you neet K+DCAN can cable and I purchased the cable from here. For F series, you need to buy enet cable.
