AdBlue / DeNox reinitalisation

Post by tmg »

Hi,

Current faults in ECM: U029E, U0431
It is recommended to do a reinitialisation of the DENOX system faults, after replacing the NOX sensor.

I am wondering how to do it with Multiecuscan.

"Adjustments" are only available for
- Lambda sensors
- DPF pressure sensors
- EGR valves
- etc...

Fiat Ducato 250 - Multijet2 140 2.3 D (Late 2019) + AdBlue

I currently don't know the exact ECM hardware and will submit this later.

Thank you.
