I have a NV300 from 2018 with 145 dci engine.
Have the fault message on the display
"Check anti pollution system"
When I connect with OBD2 it says
-fault value from Nox sensor "B" -
I have changed the sensor and removed the faulty code but it still comes back. I can start the engine 3-4 times before it get back. Are there several Nox sensors or what does the "B" stand for?
Any ideas?
