Please upload your original file (ORI). Without the dump, it is impossible to help you with the DPF and EGR off solution.

For the DCM3.7AP, be careful with automated solutions (like DaVinci or similar generic removers), as they often clear the whole DTC table or cause issues with the Gear Shift Indicator (GSI) and Cruise Control.

The best approach is manual modification in WinOLS.

• For EGR: Look for the airflow hysteresis maps and flatten them to 0 or max out the values depending on the logic.
• For DPF: There is a switch solution, but it often requires disconnecting exhaust temperature sensors depending on the specific software variant.

Make sure your checksum is calculated correctly before writing, as this ECU is sensitive to bad checksums.
