Bmw dpf back pressure sensor.

Next we simply tested sensor plausibility which showed a reading of 0 m b with ignition on engine off. Old sensor is showing 12mbar pressure with hose disconected i replaced it with new one from hella and is showi. There are several possible reasons why a dpf could be showing a reading like this. 300mb is about 4 5 psi.

You would normally measure dpf pressure in mb. When i do the dpf back pressure test with the just the engine running and no driving i have approx 12mbar at idle 55mbar at 2000rpm and 100mbar at 4000rpm these results are roughly half the bmw max recommended value. I needed to check if it was indeed blocked and the first back pressure reading showed exhaust gas back pressure at 940m b at 2 000 rpm. Hi i have a problematic bmw 320d n47d20c engine with dpf back pressure sensor problem.

A good one at idle would be 10mb or less bring revs up to about 2500rpm and less than 100mb flat out under load and 300mb max.
