Service charging system warning - car stuck in turtle mode

[Miriapod49]

Hello, guys!

Recently, I started having issues where the car would struggle to start, and after a few attempts showed turtle mode then got this "Service Charging System" message and 0% battery, even though it was over 75% charged. I disconnected the humidity sensor and replaced the battery, but these fixed the car temporarily because a few days later I got the "car-!" light back, and even though my car was 80%, it was stuck in "not ready".

I attempted to fix it again by unplugging the 12 negative and HV fuse, re-enabling contractors, and clearing faults, but still no results. Here are the error codes I am getting:
- P0B12, P1E25, P0A1F, P0E43, P1A1F, P1A21.

I want to take it to service, but until then I would appreciate some thoughts from you, guys! Thanks!

I've heard about this issue being related to a faulty BPCM (Battery Power Control Module). You might want to start by checking if the battery is working correctly.

Do you still have the HV warranty? Reach out to the dealer, and hopefully, they will do something about it.

The codes you have pointed to are issues with the BPCM (you are right @NovaNomad_). I can see you already have done some stuff. One thing, though! When you clear the codes, clear them in all modules. If you are getting ABS warnings, it might be worth retrying with the correct cables. Also, the key position should be set to MAR before clearing faults.

And the last thing (before going to the dealer), let the car enter a deeper sleep mode by leaving it off for a longer period, then recheck if the errors return. If they return, take it to the service. Good luck and keep us posted.

Did you unplug the humidity sensor?

What do you mean by that? @ChargingSpray90

You need to unplug it until all issues are fixed.

I am quite confused at the moment! I will check if I have the warranty still up and hopeful this will end fast soon enough. I am exhausted...
