ediabaslib VS imBMW

Also another project that uses that library is Ediabaslib. If youy look in the EdFtdiInterfaceAndroid.cs file you will see the following functions:

This is the one with rj45 Plug? This should be more like this https://github.com/uholeschak/ediabaslib/blob/master/docs/ENET_WiFi_Adapter.md

It requires firmware modification on the elm chip to speak the correct protocols. Check out https://github.com/uholeschak/ediabaslib/blob/master/docs/Deep_OBD_for_BMW_and_VAG.md

For sure these data aren't available over plain OBD-II because reasons VW, but could something like this work? They seem to use a hacked ELM327 to access other networks of the car (or something like that).

I did find this replacement firmware for ELM327 a while ago though... did anyone here use this ?

Fair enough. BMW seat controls are mounted in the center console and talk to a computer that sends signals to the chair for movement. There is another signal sent from the car's main computer that tells it when certain conditions are met, such as ignition on, daytime lights on, etc. Those signals are needed to keep the controls active and let the seat move. Talking with the author of the code, he was too busy to really explain what was needed but said "It's quite simple, you just need to use this code" and provided this specific link to the page.
