NOx Exceedence - Insufficient Reagent Quality
This refers to the DEF system. It can be an issue with a sensor, wiring, an injector or the quality of the DEF itself. I know they've had issues with the DEF injector.
People have reported the failure of remote start to keep the engine running under those conditions. Have your dealer check the system. I'd be surprised if there isn't a TSB out on this by now.
