Can Xhorse Key Tool Plus Program MK3 Emulator?

Problem:

 I need to add an ESL emulator from MK3 on Mercedes W204 with xhorse vvdi key tool plus.

It seems not possible to read it and then write. I can’t read data from the emulator.

i have disconnect and connect again, and i tried many times to connect and always red light because is not programmed.

Error: not connect to ESL or the cable problem.

Solutions:

The solution for write data without getting the error is to disconnect and reconnect the emulator from bench cable just before press write data button. It is written nowhere and fix the error!!!!

Xhorse ELV and Mini ELV emulator is recommended.
