VW T6 2.0 crtdi Ecu adaptation problem....

[menyhartelod]

Hi everyone, I have a VW T5 2017 with a bad Ecu. I bought a used ecu and one guy from forum tried it online adaptation, but unsuccessfully and he says: just different ecu with different flash...
But they are exactly the same. I attached the pictures and the error codes.
Can somebody help me? Thanks

My opinion is: the HW numbers of the ECU are the same, but the SW numbers are also important, but they are not visible on this ECU. They are only visible during diagnostics. Of course, these numbers must also be the same. Since there is no way to enter boot mode on this ECU, there is no possibility to flash the SW to another version. Before you buy a new ECU, you need a complete list of HW and SW numbers.
Or someone there already bought the wrong ECU before you because according to the VIN WV1ZZZ7HZJX012683 it shows ECU 04L 906 056 JS.
