Technical Soot content and DPF sensor bar

[howitt1981]

I have a 2020 Fiat Ducato 2.3 EML light on with these fault codes P1206 & P24A4 check soot level 81.56% and 14mbar on DPF sensor. Are these readings within tolerance.

Soot level (particle filter clogging) on my 2.3 operates between 8% immediately after a regeneration to 100% (very occasionally 101 or 102) at which a regen is triggered, so 81.56% would be fine.
The differential pressure varies with revs+load but if you mean at tickover at 82% clogged then I'd say that 14mbar is in the ball park.

If you're a Android user then I can thoroughly recommend DPF monitor from the Play Store for keeping an eye of DPF parameters.

In this guide are typical graphs/ values to find, also a guide as to what values (mbar) might mean
<20 Brilliant DPF causing almost no restriction
20-99 Good result and typical of a DPF in good working order
100-250 DPF causing up to 0.25 BAR of pressure – needs investigation
250-500 Serious restriction probably not allowing car to do a Forced Regen
500-1000 Performance loss very marked at this level
>1000 Car can’t pull the proverbial skin off a rice pudding. All your boost is stuck in the DPF

I'm having the same problem did you get it fixed mine is also a 2020 Ducato with 12000 miles on the clock
