EDC16CP34 checksum correction - mike1 - 26-11-2023

Hello. Have got a Audi A6 C6 3.0tdi with ecu damage - internal module error and starts for a sec and dies.
Have got a donor ecu with the same numbers (4f0907401A/0281012153) - tried to transfer full data with Ktag clone - engine will not start after that (starter runs). No additional fault codes. Tried reverting back to the ecu original files - same result - will even not start for a sec. 

Ktag stated checksum error while reading ori backup file.

Anyone able to check/correct checksum for donor ecu?
