Citroen Jumper III (Ducato 250) DPF replacement

[kaya]

Hello guys,

i have a strange problem with a Citroen Jumper III, we replaced the DPF, the Differential pressure Sensor, both the Temperature Sensors and we cant register the ECU to replace the DPF.

The ECU doesnt have any errors recorded, the only one is P1250 but i can delete it after i reset oil and sensor replacement functions (the funcion above dpf replacement, i dont remember the correct wording and screenshot is missing that part)
So no Check Engine Light on dash and in the ecu memory

I have attached a screenshot where you guys see the actual problem, it keeps telling me that it Failed to Execute and by Incorrect conditions to run this test!.
Ignore the Water temperature in the screenshot, i took it later when we gave up and decided to ask for help in the forums =)
And is it normal that our Differential pressure sensor shows 0 mBar even when engine running?

Any help would be appreciated.
Kind Regards

Hey folks,

the problem is fixed, it was a modified Software on the ECU which the dpf was not removed propery.
After reverting the modifications and flashing stock software, the particulate filter stuff could be fixed.

Kind Regards
