My NOx sensor was flakey, well, most of the first year I had the car. Turned out to be a nicked wire that corroded. May have come from the factory that way, but could also have been damage done during servicing -- it all has to come apart for a flywheel replacement.Took it to the dealer part of on order. They tell me it's fine to drive.
Does anyone know if the DEF and regens will be affected by the NOX 2 sensor being faulty?
I'm over 32k miles now and have no emissions issues at the moment.
