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.

The codes above are after a reset and ia lready tried to start without the IBS pluged. Going to work on it a bit tomorrow though and may trace back my steps again.

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.

He diagnoses and tells me what it is and I go thanks, I'll fix it myself. Or if its something out of my league, I pay him to do it.

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.

When you come to a forum especially when you are new take what you want and leave what doesn't make sense to you. No one on here has told you to search for your solution before asking a question because we are not telling you anything different from anyone else with your same symptoms. Your issue will take time and many ideas to figure out, especially when your diagnosing with whatever you have pulling codes. Get INPA and ISTA and you would have figured it out on your own or you can take advise and let the owners on here help you with your issue.

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