How to fix Audi A6 2006 ESL Fault Motor

I got Audi A6 2006 ESL fault motor is working but steering lock not locking or unlocking, car can not start. below is photos any idea how to fix this issue?

I was suggested replacing with good used ELV. But in my country it is hard to buy esl alone only complete system. Can i find used good one online or can i do ESL adaptation by vvdi2?
Final solution without buying ELV:

Just read the ESL J518 by obd, if you have a working key.
Or with a ECU programmer like xprog or Xhorse vvdi prog.
1L59W or the 3L40KEEPROM 2KB
FLASH 128KB

And copy this in to the replacement part.
Make sure that you have the correct part number.
