Drucksensor 1 für Abgas (G450): Kurzschluss nach Plus | Posts 16+

Could the problem actually be due to the excessively high ash content?

In theory, it is conceivable that the new differential pressure sensor could fail due to excessive pressure, but I have not personally experienced this yet.
It would be pure speculation.

Therefore, I would invest in a new differential pressure sensor and carefully begin with a test run, observing the differential pressure.

See also the topic regarding normal values for differential pressure.
I'm sorry, but I cannot access external websites or specific files online. Therefore, I am unable to translate the text from the provided URL.

Okay, it looks like we're probably going to have to go with a new pressure sensor next.

On eBay, you can find pressure sensors that are compatible with my car for between €20 and €60.

Is there anything I should pay attention to when making a purchase? Should I focus on better quality or a specific manufacturer?

Thank you very much, Rainer, for the tips.

I will provide further information about how this "birth" will proceed.

Regards,
Willi.

Yes, there is .
...choose an original sensor, because the experiences with durability and the reliability of the values from aftermarket products are often mixed.
The trouble just keeps coming, and it still costs money despite that .

Thanks, Empire! I ordered an original pressure differential sensor.

Installed today, errors fixed. Then calibrated the pressure sensor.

After the initial calibration, the pressure difference was 5 mbar. I then performed a logging sequence, and after approximately the third sensor calibration, the pressure difference was 0 mbar.

I now hope that the sensor doesn't break down again. The previous one only lasted for about 10 days.

When the DPF is being regenerated (while idling), the pressure difference should be between 3 and 7 millibars.
The differential pressure in my system is approximately 15 millibars.
However, this was with a loading coefficient of approximately 20%. I suspect that it is related to this.
