RE: N47 DPF backpressure sensor problem
To be sure I will change sensor for new one, often after dpf problem sensor also is broken, it's not expensive.

RE: N47 DPF backpressure sensor problem
Guys, please read what I wrote. Almost every question was answered earlier. Car is stock, iLevel from 2018, detached sensor shows same value with pipe detached (when engine off) and I sensor is NEW OEM and I tried few new parts (2 OE, 1 Hella, 1 Febi and 3 used OE). None of them was showing 0mbar when engine is off.
The problem is that value should be near 0 when engine is off but it isn't. |

RE: N47 DPF backpressure sensor problem
Did you check DDE plug connections/pins for corrosion and damage. Sensor plug for supply voltage, ground and signal? Is atmospheric pressure sensor value plausible?

RE: N47 DPF backpressure sensor problem
There will be no more updates from me
 Decided to go for S169A and removed DPF. Filter inside wasn't damaged physically but somehow when car did regeneration backpressure values stayed the same all the same. Now there is no problem

RE: N47 DPF backpressure sensor problem
Take both sensors on bench, supply them and messure presistance. I beliew back presure sensor is resistance based.
Then you will see, maybe you have dme damaged or some software issue. |
