Hello Vyckal and all other,
I have now the same problem with my 300C. I'm trying to fix it now for 2 weeks but unfortunately no result
. You write in your first quistion that you have replace the Exhaust Pressure Sensor and now you write that its fixed because you bought a sensor with part number 05175812AA. This photo shows the Exhaust Pressure Sensor. So I dont understand it??
First I go to the Chrysler dealer and they check for error code's. I have the same error code P0471. They have change the Sensor but give still the same error code. They told me that I have to check wiring from the Sensor to ECM. I have checked al the wiring but there is no problem with the wiring.
So I dont know what the problem is!
I had also a hole in my DPF because the DPF was broken from the rod. I have detached the DPF and welded it. Is that maybe the problem? Hope someone can help me!!!
