2016 Tera World REx

It's my first electric car and my second BMW. I bought it second hand in October 2023 with 72,000 mi from the local BMW dealership. It had belonged to an employee and luckily for me it was immaculate. Unluckily for me it's starting to throw codes for all kinds of things and so I'm on all the forums with everybody else trying to decipher what they all mean in dollar signs lol. Ironically, despite the CELs, I've never actually had an issue with anything functioning properly. Yet

Check to see if your 12V battery is pining for the fjords. If it's over 3 years old, it probably is. Worn out low voltage battery can cause a British boatload of seemingly random error codes to get thrown or even leave you stranded at the worst time.

Bimmercode shows the 12v battery was registered at 69k mi. Be nice if it was something simple like that.

Still, I would double check the actual health first, it's rare maybe, but batteries can fail or have a defect out of the factory. Otherwise, you may go to the dealer for a diagnose although they may charge you for that. Good luck, I hope it is something easy to fix.

Thanks, I'll look into it. I've been using Bimmerlink, Deep OBD (ISTA), and my older Bosch scan tool just for fun, and they all disagree on the cause of the CEL which is super frustrating.
