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.
I understand that...the question is that i dont understand this ecu well so i need hel to find maps
otherwise i would try myself
~I normaly work with soft not with manual solution but i know is the better way, but betwen children,garage and clients very few moments i have to study this ecu or some of new one's

Please post the Software ID (e.g.
U... or P...). Since I cannot download the file right now, having the ID will allow me to check if I have a matching Damos or project to give you the exact addresses.For EGR, you are generally looking for Hysteresis maps.
- Search for 16x1 or 20x1 maps.
- In 2D view, they look like a "step" (High values on one side, Low values on the other).
- To turn it off, you usually fill these maps with
0.
For DPF, it is more complex on DCM3.7AP and usually requires a switch solution plus DTC handling. If you post the ID, I can be more specific.

I cannot see the filename on my current view. Please type the Software ID (e.g. U2A4N0...) directly in the post.
For EGR Off manually on DCM3.7AP:
- Switch to 2D view in WinOLS.
- Search for hysteresis maps (usually 16x1 or 20x1).
- They typically appear in a group of 4 maps close to each other.
- Fill these maps with 0.
For DPF, it is much safer to use the correct switch solution rather than deleting DTCs blindly. Once you post the ID text, I can check if I have the correct mappack or address for you.
