I have an intermittent chgeck engine light at the moment, and bought a iCarsoft 980 to look into it.

Some of the readings are below:

118d00 DPF fault code - "B28/8 DPF differential sensor Plausibility Error"

After the code was cleared, this read 8hpa and higher when revved at idle.

  • Ash 0g
  • Load state filter 3gram
  • B16/14. 0 deg C.
(there were lots of other temperatures - all above 100 C once the engine warmed up)
  • Current km reading: 64,937
  • Distance since last particulate filter regeneration 63,900km

My conclusions:
1) This DPF is basically OK
2) 3g Load and 0grams Ash can't be bad?
3) There's possibly a sensor error (the B28/8 issue)
4) The B16/14 reading of 0 degrees is inexplicable, but the car isn't complaining about it, so neither should I...
5) Equally inexplicable is the DPF regen when the car was new, and not since (although I'm sure it has done at least one regen @55,000km ish - lots of noise, fans, burning smell)

Can anyone help me interpret the above, or suggest additional codes to read?
 
I'd change the pressure sensor, if that's playing up it might not regen when it should.
