hello everyone,

tried the dpf off switch on this version but have limp mode with a DTC U0301. I have removed the senors but was all the same.
Can someone help with a proper solution?

regards

ohhh my Good, people you not think what you doing , you cut dtc Can information.... In this ecu when you off dpf to switch you must disconnect all temperature sensor and diferential pressure sensor, ecu have sensor resistance and you have light on with nails. Now you have switch off limp but car not have power because have emergency mode ..........:palm2::palm2:

@Voltechcar: You mean on my file? Not good? Because i do DPF off and disable DTC.
So in this case, disconnect all sensor and all ok?

i tried the method with the switch and disconnected Sensors, like i mentioned in the first post. I had still the error with incompatible Software, U0301. The information i got that on some Software version it is not enough to just disconnect the sensors.
