New battery problem

2008 e92 · 02-13-2022, 11:49 PM

Hi everyone,
I have a 2008 328i e92 coupe.
I got two codes and not sure why. Please help

My old battery was completely dead for a few months. Today, I got a brand new battery from a BMW dealership, same amp. I installed it and registered it with Foxwell NT530. After that, I did a scan and these two codes still there.

2DEC. DME power management: battery.
9CB5. FRM: battery exhausted.

Am I supposed to clear them after I installed and registered my new battery?

The car starts good and runs good.

Thanks

Clear the codes. If they come back, then more diagnosis is needed. I doubt they will come back. The E90 doesn't like being with out electric power.
