You can try reflash with .sgo file

No way with reflash....This is only for mcu...Checksum is for eeprom dump....

You need full flash read from nec and a eeprom as I believe is diesel cluster. Maybe I can help with files from my Octavia, i must check which pn i have.

Flashing is posible with sgo file but this not solve the problem...Checksum is in eeprom 24c32...
