Strange Issue with Battery Drain
Had the battery drain while stopped error, battery died overnight while sitting. Had battery replaced. Same issue a day later, dead battery. Charged battery up and car runs fine, but I'm concerned about the battery drain issue. Used Bimmerlink to export errors and listed below. Any ideas of where to start?

There's too much there to make sense of it. Clear them all, see if any come back. The two most common parasitic power drains are the dashboard and the water pump. Both have been extensively covered here.

I cleared them and the main ones I notice come back were...
801237: Rear window heating: Reduction of heating output due to power management and 030120: FH FAH: The system is not standardized I'll export and upload the full list after clearing tomorrow |

Cleared memory, let it charge overnight, sat all day today. Crunk it up and these are the errors now.

Try to clear errors and check for errors right after the battery is fully charged. If you let the car sit (presumably) draining amps and then measure, it will throw too many error codes.
Are you driving the car after the battery full charge? Or just let the car sit and then measure? Trying to eliminate the alternator. If you did not drive and still drains in a day, then battery is bad or you have a significant short. Best would be, if you had a clamp on amp meter that can measure below 2-6 Amps. And check the amps with trunk open (close trunk lock latch manually to turn off trunk light). Watch amps during next 10-15 mins while car goes to sleep.

I've driven it all day once it is charged. Seems to be no issue with the alternator as the drain doesn't occur once I have it running for a bit. I checked batter level using Bimmerlink after driving it for two hours and it was at 99%. After having it parked and off withouth the alarm set for about 3 hours it was down to 88%

Looks like something is drawing power. You can go by the tedious and hit and miss method and start pulling fuses, or invest in a DC clamp on meter for about $30 up to $60. It should be able to measure below 10A with decent resolution.
Recommend the UNI-T UT210E Digital Handheld Clamp Multimet. 2A setting. https://lygte-info.dk/review/DMMUNI-TUT210E%20UK.html https://www.amazon.com/UNI-T-Digital...4C7I3ZAB0&th=1 https://www.ebay.com/itm/28537906212...caAhBGEALw_wcB EDIT: UT210E is better than UT203+.

Never done this type of troubleshooting, so help me understand the process. My understanding is I'm clamping onto the + batter lead and reading meter. Pull a fuse, check for a drop. Once I know where the drop was on the fuse, then I look deeper into what all is on that fuse and go from there, right?

You can clamp it on either the positive or the negative, doesn’t matter. Make sure you set the clamp on meter to DC and not AC. Also, I would set it at 20A or higher at first because tha car will draw 10-12A normally before going to sleep. Zero the meter after you initially clamped it on.
Before you even start anything, when you pop the trunk open, push the locking latch in with a screwdriver so the trunk light goes off. That way you can keep the trunk open and monitor the amp meter visually. Lock the car with the remote and move the FOB out of range. Observe the amp meter for the next 15-20 minutes. When/if the amps drop below 2A you can switch the meter to the 2A DC! scale and zero again. But if you have a large drain you will probably not see it go below 2A. With the amp meter on the battery, before locking the car, it will read probably between 10 to 12 A. After locking it, it should slowly drop down to 4 to 6 amp in about five minutes or less, and then down to one or 2 A under 10 minutes, and then drop below one amp eventually down to between 20 and 80 mA During this time, you should listen to any sounds or noises coming from the engine that would indicate something is still running. .

Open the doors & trunk hood. Lock it with screw driver then press lock key with remote.
Let it sleep for 1 hour don't bring car key near once car goes sleep. Take a look on all fuses & relays with thermal camera, or try to find out heated fuses with electric thermometer. little cheaper then thermal camera |
