You need to be focusing on the CAS errors. With those errors you're not going to get it to start. Those are due to a power issue somewhere. My suggestion is to clear codes and see which ones come back since you don't have the software to properly troubleshoot. The first thing after code reset is disconnect the IBS and disconnect battery for 20 mins it should start right up after reconnecting battery (keep IBS disconnected). Then find out why you are having a discharge.

Did you disconnect the Mass Air Flow sensor and see if it started?
Did you disconnect the IBS wire on the battery (negative side) and see if it started?
Did you enter the eBox under the cabin filter and check the middle fuse in the black box that has 5 fuses all in a row?

Or you could take it to a BMW indy mechanic and let him figure it out. Then decide whether to let him fix whatever he finds or fix it yourself.

You can't rule out the braided ground cable known fault (near the exhaust manifold).
Check to see if its green and corroded.
You can run an experiment and use jumper cables to "ground the engine" and see if it starts.

The people responding to you have been contributing (volunteering knowledge) to this community for a while and @donpb didn't deserve your response.
