36E000 - Nox Sensor after Catalyser

[MorELO90]

Hi Folks,

BMW X3 G01 LCI SDRIVE18D 2023

I've been having this issue for a quite while now, 36E000 with the Engine light ON. The car is driving fine without any loss of power.
With ISTA, I reset SCR adaptations and delete fault memory : it goes off for 400-500 KMs, then it's back !
I bought a Frankberg Nox sensor (based on OEM number) but it was not recognized by the car, so I fixed back the original BMW Nox sensor. I still having the issue...
Anyone having the same issue ? any solutions ?

Thanks
Morad
