Here the dump file read in Mode 1 from the 35128WT. FFFF everywhere..

The programmer doesn't read anything when all content is FFh.

Try MODE_2 variant in attachment. But be aware that you have to code the cluster because beside the odometer, everything has FFh instead of the expected data.

Thank you.

Unfortunately it was impossible to write the new dump:
In mode 1, I have immediately the error message: Mileage more than 800.000km is not supported
In mode 2, the process takes about 20 minutes for calculations, then I have: write failed

Except BMW Explorer, no available other solution for the chip 128WT ?
