AUDI A6 C6 ECU synchro

[Fuller]

Hi I replace ECU in AUDI A6 C6 and I try to synchro new ECU with car but car won't start.
At first copy all eeprom from old ecu to new and car started but i have some dtc about bad coding of ECU.
And now I tried copy some lines with PIN VIN and CS from old ECU to the new and I haven't any DTC's but car won't start and probably ECU still resychro with car.
Somebody want help me to synchro this ECU?

Eeprom alone is unlikely to be enough. I can try to help you, but the solution immo off
