Workshop workflow
- Read the MED17 ECU via CAN UDS using your flasher of choice.
- Open Softechpro V5 and drag the .bin / .ori / .hex / .s19 / .frf onto the workspace. The MED17 variant is auto-detected.
- Select the service from the tab (DTC OFF / EGR OFF / DPF OFF / AdBlue OFF / Stage 1-3).
- Save patched .bin — TPROT-aware checksum + signature is recomputed automatically.
- Flash via your existing flasher. Adaptation reset on the OEM scan tool if required (typical on AdBlue OFF and IMMO OFF).
