I had this happen twice to me, with the 'poor quality DEF'. I added some newer DEF. (even though the tank was over 1/2 full) drove about 50km and the warning went away.

I Just received a recall notice about Nox1 sensor (replace req'd) and or soot buildup on Ox sensor (nothing about replacing it?), think it might be related to the 'Bad Def' readings people are getting.

Great the 'poor Quality Def' is back, hit on the way to work this a.m. Last-week I called the dealership about the recall -we need to order parts, called today still no parts. Why did they send me a notice that the parts were available? And this is the dealership that can't change the oil properly... great. next closest dealership is 1hr away.

And so it begins, caught a P249D on the way home. Cleared it in the driveway, came right back on restart.
P249D -> Closed loop reductant injection control. control limit reached low flow detect.
We just stepped into winter a few days of freezing weather. I'm thinking heater also.
I filled the DEF last-night and cleared the code 1/2 way to work this am, stayed cleared, will monitor.
This would go hand-in-hand with the 'poor DEF' warning.

Well, I had the CID in Thursday for the Nox1 sensor replacement and Regen
before going in I had the 'Poor DEF' warning and the 'P249D' -reductant injector control
I won't go into a rant about the 'Service cloud' the dealerships have placed between the customer (-me) and the mechanic (-guy I'm paying to fix the car)
-The sensor replaced, took 3 tries to get a regen to complete, it kept kicking the mechanic out ( said the cloud).
-Your car is ready sir, oh, the mechanic suggested driving the car to clear the 'Poor DEF' alarm.
-on the way home scan-guage RGN posting 0 for 10 seconds then alternating 1 for 10. hmmmm
-finally 2 RGN
-Still 'Poor DEF' warning..going to 80km -with warning it will go to 6km in short order
-on the way home stopped for alcohol (to go) to wash away 'Service Cloud' taste
-take dog for drive 20km -no change
-call 'Service Cloud' Still 'Poor DEF' need car for Monday
-take it back to dealership, leave it overnight
-pickup Friday no 'Poor DEF' warning
-'Service Cloud' upset it took 3 regens to clear alarm
-paid 'Service Cloud' $242 the cost of the regen on Friday...
Went home washed away 'Service Cloud' feeling...

Got my first RGN today since the dealership cleaning, it started right at 22 STM and finished at 3. I went 1425km (before regular was 900-1100) since the dealership and only took about 12 [email protected] 108km. everything copacetic I was on the highway, so I didn't notice any MAP drop.
