I3 SME coding - LB2020 - 08-09-2025
Hi, need assistance with coding a used battery pack to a BMW i3.
Replaced my 60ah with a 120ah and need to match the new SME to my car. I have esys and the same PSDZdata as what is already on my car. The 120ah battery is on a older software version than my car.
I have found 2 solutions that I think may work but not 100%.
Option 1. Detect CAF for SWE for SME then update with latest software
Option 2. Use tool32 to read old SME ISN and copy to new SME.
Am I looking at the right options or is there more to be done?

You can't virgin used SME with normal BMW tools like Esys or ISTA+, you need to read the Eprom with external tool like VVDI MULTI PROG or Memtool.
