Check Engine 45NOX
Hi All,
Just completed Oil Change & Air Filter change on my 2008 r350. (service C) Drove it about 20 miles, no issues. Filled up with 93 octane and put in a bottle of Lucas injector cleaner and drove another 20 miles, no problems.
Pulled into the garage just now and check engine light came on. Dug into the service area of the instrument display (where you go to reset service reminder) and there is a highlighted message that reads 45NOX.
Any idea what this means? Engine could not be running smoother. I'm due for in inspection this week and if this is emissions related I'll fail. NY requires all codes be cleared for a certain period of time before they will pass it.
Any info is appreciated.
