Hi guys
Mercedes 2020 year model, X290 AMG
After the accident car is not starting, and 2 faults on G1/3  48 V battery. 
I disassembled battery and internal motherboard, it looks ok.

It seems like crash in software of control module of 48 V battery. which is blocking engine start and battery operations itself.   

I tried with Xentry if this is any function or way to run battery again, but useless, (No online account to software update)

Autel also does not support SNC or Coding it. 

Please help if anyone has expeirence in repairing or solving the issue, ready to pay for help...

There is internal electrical fault.

First charge the battery voltage to about 48V, and then use the programmer to write the battery data, it can be perfectly repaired
