Technical DPF clogging percentage parameter

[integrale4ever]

Hi,

I have a question regarding the parameter "Particulate filter clogging" that can be found when connecting with the MultiscanECU software. My parameter is increasing at a high rate indicating that my filter is getting clogged often, (starting active regeneration at every 100-150 km). I have monitored the differential pressure sensor and its value is "normal" from what I have found in different threads on this forum (1-40 mBar).

What other sensors are involved when calculating the "Particulate filter clogging"-rate?

I am not receiving any ECU errors, which is odd.

My car is a 2009 Lancia Delta 1.6 MJT diesel, 120 bhp which has the same engine spec as in the Fiat Bravo II.

I would have checked on my Doblos both 2010 1.6MJ but neither have DPF.
What sort of use do you do.
My daughter with a 2010 1.6 Golf Plus had issues due to short journeys to work and engine not warming up enough.
I put a new thermostat in so temp reaches 90degrees Centigrade quickly in middle of gauge, put DPF cleaner in her fuel every other tank full and when possible give it a 30 mile run with revs above 2000rpm at least once a month.
A friend, a retired Motor home mechanic on Fiat Ducatos said the first thing they replaced that gave trouble on them was the DPF pressure sensors.

I am using the car mainly commuting to my job, 75 km each way, 80 % on motorways.

I have changed the DPF and turbo and as the pressure sensor indicates, it seems to be quite low readings. The EGR has been cleaned and its its actual value seems to be the same as the desired value. The values are fluctuating a lot, is that normal?

My main question is which sensors that contributes when calculating the DPF clogging rate?

Others on Forum may have more specific advice, all I can find in the 2010 Fiat Doblo 1.6MJ Owners handbook is this below.
On some makes of vehicle where additives like Eolys Fluid or the later AdBlue is used they seem to measure the opening of the fuel filler cap as one of the details required to trigger a REGEN of DPF, this is fine for people who drain and refill the fuel tank, however it causes problems when people only put a few litres at a time in their vehicles due to a misguided sense of economy
