well i live in florida so no need for them but i remote stat from inside the house and walk to the car. im sure it primes the fuel pump and glow plugs. but when i manually turn it on i wait for all the lights to turn off so figure the glow plugs have turned off by then.

I was referring to oreo when he stated that after the recall he was having cold weather start issues, but yes when you remote start, it waits for the glow plugs to finish their cycle (if needed). Since you're in florida, you may never or hardly ever see the glow plug light. They are very quick when compared to other glow plug systems I've seen. But the light on the dash is yellow and kind of looks like a coiled up spring.

Oreo, something you may want to try is to cycle the glow plugs twice before starting. Turn the ignition on, wait for the glow plug light to go out, turn the ignition off for about 5 seconds, then turn the ignition back on until the light goes out again, then start. I'm curious if cycling the glow plugs twice like this will show any improvement or not.

Just an FYI, in modern diesels the glow plugs stay on.

Not all the time, and not for very long, and not at full voltage. And the reason is to clean up the fuel burn when the engine is not at full operating temp.

see last diesel i drove other then my cruze was dads ol freightliner. when we where in new Orleans after katrina it was snowing and we had to keep the glow plug on for roughly 1 min and fired right up, then turn the toggle for them off. by the time i hear the pump finish priming the plugs indicator have turned off.

Exhaust Gas Temperature Sensor #3 and the NOx recall

I have been reading through several threads and posts regarding this recall as well as the system warning I am getting, but I don't seem to be finding what I am looking for. I guess I wanted to post to see if anyone else is having my issue.
I had these recalls done to my 2015 cruze and I have been getting the Service Exhaust Fluid System Now along with the CEL and countdown. I did motor vehicle repair in college but went on to become an Industrial Mechanic, so I am understanding of how systems work.

SO ON TO MY THOUGHTS...
As I have read up on a lot of what can come of this system warning light (mine being ETS #3), I see that most diagnoses could come directly related to the Emissions system, that is what this recall is about. I called GM about it and they told me unless the recall states exactly what the component is that needs to be replaced they will not cover any other work related to it. I do understand that at the end of the day all systems could be related because they all work together for the operation of the car. However, when there is an outstanding issue with this NOx recall and the issue I am having is components within this system, I feel that the defects are creating the issue, I am not understanding why I pay out of my own pocket to repair components effected because problems they are recall.

Any thoughts?

I noticed this old post of mine and have some info I forgot to share. This summer I cleaned the throttle plate and as far as a toothbrush would reach into the intake manifold with maf cleaner.There was a fair amount of crud on the throttle plate.The car was a bitch to start after this but once it did everything was ok going forward after that.I have noticed a big improvement in cold starting,not rough like before in the cold and way smoother in the summer.

The NOx issue would not in any way induce a failure of that temperature sensor. Yes the system uses many inputs, but the nature of the recall is mostly a computer reprogram, and NOx sensor replacement, that would not cause a EGT#3 failure.

The DEF "service exhaust fluid system" is a different issue.. do you know the DTC (diagnostic trouble code)? It is possible it is the DEF heater and here in the US there was an extended warranty on that item, so it MIGHT be covered.. assuming that is the issue. I had the DEF tank replaced on my 2015 at no charge, under that extended warranty.
