I have an e87 2008 LCI with N43 116i petrol.
INPA shows on Exhaust Live data that as the exhaust temp increases , NOX sensor starts picking up with different readings.
Suddenly the NOX readings disappear. They might or might not reappear after a short while.
So , my NOX sensor is working . Right ?
Why does the car throws these errors 2AF2, 2AF4 & 2AF6 ??

There is no issues with the cars running ...
