Did you or the dealer run the diagnostics for the SCR system?

Adblue quality test with a refractomer - must be 31.8 => 33.3 %

Check the metering valve for crystallized Adblue

Make sure the dosed quantity is right - perform the 50 minutes ISTA function test to check the NOx sensors and SCR catalyst efficiency?

madbim,
Did you ever sort the cause of this code?? Seems I am going down the same path with my 2013 X5

replaced both Nox sensors, reset Adblue level went for drive on interstate.

BMW just recently extended the warranty on NOX sensors you should check to see if your covered.

Let us know if you have it, for my 2011 x5 35d it doesn't show nox?

I'll have some used NOx sensors available soon. I'm right in the middle of my delete.
