DPF workaoround
I'm searching for a way to trick the ecu to sense that there is no soot in DPF and doesn't need to start regeneration.
As I seen the c250 cdi w204 has only 2 sensors on DPF , one differential pressure sensor and one temperature sensor. So, if I can make the differential pressure sensor signal to have a certain value (like 0,01) and the temperature sensor signal have a certain temp reading( like 200 degrees) then the regeneration should not start ever right ?
Can anyone tell me how to find the sensor value that triggers regeneration ? Am I missing something ?

Ummm there's alot wrong here..
If you prevent regens the dpf will block .
Giving a differential pressure sensor too a low reading will make it think it has a leak and go into limp mode .

Yes blocking regeneration will block dpf , but also can be a workaround if dpf is empty ( no ceramics inside).
Do you know if there is any other sensors that contributes to soot level calculation , or only the differential pressure sensor does the job ?
