Technical 2016 Fiat Ducato X290 DPF lost

[PapyPachy]

Hello everyone, I bought in fiat ducato 2.3l 130CH in June 2024. but I just start to ride with for 2 months.
I now have a very significant power loss. after a long investigation, it is the DPF that is blocked.
When analyzing the differential pressure sensor in MULTIECUSCAN, there is no data.
With ALFAOBD I have the message like not taken into account by ECU.
The same is true for DPF temperature sensors: they do not appear.

By connecting to the Body ECU I went to see the configuration of the vehicle and the DPF was "desable".
I changed it to "ENABLE".

Now the Body ECU is informed of the presence of the DPF.
Unfortunately I still do not have information of the DPF pressure and temperature captors that go back to the engine ECU. Apparently the engine ECU still does not know that there is a DPF .
How do I tell him?

Do I need to realign the PROXI or reset learning or something else that I don’t know?

Short answer, i dont know, this is a new one on me (almost) have you actualy succesfully run it and itis just now playing up?
A new proxi align is a good idea but make a backup first. Is it possible that it has had a remap with the dpf deleted (guts removed) and as a result the differential dpf sensor is either mapped out or reading correctly in that there is no difference.

New proxi alignment with Multiecuscan

To create a new proxi file (once you have changed things that need a proxi alignment). For example changing an airbag module. Prior to any proxi alignment it is advisable to create a backup first. See guide...

Thanks theoneandonly the proxy realignment didn’t give anything, everything was ok.

I think the previous owner had remap.

I would have to go back to the original state, but I don’t know how to do it.

to return to original state you would need to know what has been deleted and what should be there. What year is the engine is it single egr pre 2017 twin egr 2017-2019 without adblu or 2019 2.3 with adblu (this maybe a 140?)
