Citroen Relay 2012 DPF ISSUE

Unread post by vamzdis50 »

hi i just got my DPF cleaned report said it restored back to 100% efficiency . how ever ~200km after ecu calculated soot load of 230g and giving an warning about it then a week later it went into limp mode .i would assume DPF it self is ok rather ECU calculates soot load wrong based on some sensors ? DPF pressure on idle is ~30mbar so i am not sure where the issues is coming from or what is the formula used by ecu to calculate soot laod and weight ?

Did you program the ECU that it had a new DPF fitted after completing the work? :)
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!

So dpf is not new it was just cleaned . and soot model was reset back to 0 before installing it . but then about two weaks later soot weight climbed up back to 220 i did a 160km drive on a motorway which dropped back to 120 and now after ~week its back to 260g
