Differential Pressure Readings of Diesel Particulate Filters (DPFs)

[Lucas_Smith97]

Greetings,

Regarding the subject of the W212 E220 CDI, it is worth noting that this particular model has garnered significant attention in the automotive industry.

What are the recommended values in bars for the DPF Differential Pressure Sensor (icarsoft)?

Furthermore, could you please clarify the recommended values for Fill Level, Soot Content, and Ash Content? Are these parameters subject to variation depending on the recency of the automatic regeneration process of the Diesel Particulate Filter (DPF)?

I express my gratitude for your assistance.

I am now seeing similar inquiries, which have prompted the acquisition of a new diesel particulate filter (DPF) sensor that is scheduled to be installed today.

It is uncertain if the fitting instructions for your specific vehicle will align with those shown in the movie. However, the video provides a comprehensive demonstration of the sensor replacement process for the W212 model.

Thank you for providing this information. I have come across a helpful video on YouTube. In a different thread, I posed a concern about the potential consequences of modifying the problem at hand. Specifically, I am curious as to whether it would still be necessary to rectify the fault or whether the Electronic Control Unit (ECU) would automatically identify the appropriate reading and reset accordingly.

Are you referring to the Diesel Particulate Filter (DPF)?

The first issue with my vehicle was the illumination of the engine management light, accompanied by an error message from the icarsoft diagnostic tool indicating a problem in the input of differential pressure sensor 1 inside the diesel particulate filter (DPF) system. The presence of an invalid signal has been detected. The pressure measurements recorded at idle conditions were seen to be 0.01 bar, but during maximum revving conditions, the pressure reached a peak value of 0.08 bar. The sensor was changed during the last few days, resulting in the Electronic Malfunction Indicator Light (EML) being on for a brief period before thereafter extinguishing after a few miles of operation. I have now traveled a distance of 300 miles and the malfunction indicator lamp (EML) remains off. Upon conducting a further scan, the error codes persisted, however I am uncertain as to whether I had already erased them. Once the vehicle is returned to me by the Mrs, I will proceed to conduct another scan. In the event that the efficacy of the new sensor is confirmed, it is probable that the fault codes will need to be reset subsequent to the installation of the replacement sensor. It may be inferred that the replacement has been successful, since the Electronic Malfunction Indicator Light (EML) has not reappeared. The introduction of the new sensor has resulted in pressure readings of 0.0 bar while idle and over 0.1 bar when the engine is revved. This prompted my first inquiry to verify these values.

[Lucas_Smith97]

Indeed.

[John_Doe1975]

This would be logical in such case.

What other potential expansions may the acronym DPF represent?
