Mercedes W202 4E28B ECU RENEW

[Griunvaldas]

Hello, could anyone help me renew this ECU? I searched DK and there exists 2 ways - one changing just one byte to FE, and the other filling with FF and adding D3 in one place. I don't know the difference and don't have possibility to experiment. ECU type is ME2.1. Thank You! 412362

There is something strange in your dump - VIN is missing. Either you did not read it correctly, or the ECU is damaged. Anyway, please try mercis dump and report
