How to Disable DPF for BOSCH EDC17C81 EDC17C53 EDC17C63

In the electronic control system of diesel vehicles, there is a protection mechanism for the DPF filter system. When the ECU computer detects that the efficiency of the DPF has decreased or is abnormal, it will issue an instruction to limit the torque output of the engine.


In layman’s terms, it means that you can’t refuel, you can’t run, and you can only run 80 yards at most. . . And it will report fault code P2463


Here show you guide on how to disable DPF for BOSCH EDC17C81 EDC17C53 EDC17C63 by manual.More DPF disable topics,please refer to:DPF Clean/Disabled
