Not sure exactly what you mean by concerns..given your differential pressure is low..
We had a discussion on this topic a while back on a thread and think its safe to say you don't want to be getting wound up by the scan tool data on % soot loads as long as you are regenerating and it falls .. The pressure across the unit is a far better guide .. My torque app did give temp readings on the exhaust but sorry I can't remember if it gave the differential pressure data..it is listed in the data available , but can't remember viewing it.. |

DPF fills up and burns out : 20 ... 90% in one cycle That's for normal use. You're @28K - so your DPF will be fine for another 100K - at least You cannot deduct its life expectance from sensor (ECU) data. But you may display these data with a Nanocom. |

Thanks for the replies on this - and apologies for any confusion and my lack of insight into this subject.
Can anyone tell me whether there is anything that is dash-mountable that provides realtime data for things like oil / water temperature, DPF pressures/status... etc? Thanks. |

I use a scanguage, but there’s also ultraguage, or you could use an odb2 dongle & app.
I have a scanguage which I use to display coolant temperature, oil temperature, soot level & battery voltage. Lots of posts on here about these. |

Many thanks, really helpful.
There seem to be a few different models of Scan Gauge - is there a Puma 2.2 specific compatible version or are they all compatible? I’m specifically looking for the DPF data (soot level and differential pressures) but would also use MPG and oil temp, etc. |

I have the scanguage 2, which is a few years old now. In relation to the DPF specifically it only gives me the soot level. However it also shows the exhaust gas temperature & EGR angle, so I can see when an active regen is happening.
This page has the details for programming "x-guages" specific to the puma 2.2. [url] https://www.scangauge.com/x-gauge-commands...2l-diesel/ [/url] If you come across a small device suitable for placing on the dash that displays additional DPF parameters, such as the differential pressure, I'd be really interested to hear about that. Warning: Monitoring the soot level & miles between active regens can become very addictive!  |

Many thanks. I think I'll see how things go. As you say, some things are better unknown and having something like this might become a 'distraction' for me!
I'll hang on to this information and see how it goes.  |
