Stage 1 abs /traction light triggered

Nice — that’s exactly the right info.

So you basically used the donor’s ECU HW/SW as-is (HD + SW matching the donor list), then did virginizing + SCN/ISN setup via Xentry (SamiK offline), and after that the ABS/traction lights cleared. That strongly suggests the original issue was the ECU identity/ISN/coding mismatch rather than a genuine ABS hardware fault.

If you can, post the exact Mercedes part number and Bosch number for the donor ECU (and the ECU SW version if you’ve got it), plus which Star path/module you ran for the SCN/virginize (e.g., ECU coding “replacement” workflow and which control unit was used). That will help people replicate it precisely.
