Dealer Tech's have no answer to problem
Is any one else having this problem :2011 6.7, Engine light on steady,tech downloads and resets for Nox sensor and mass air sensor,light back on in minutes and continues. Truck is in alberta with lots of idle time due to cold weather and work truck. Dealer says that changing sensor will not fix problem as others have done so and no change. The big worry of the whole problem is that the oil level is increasing !!! Engine will create about one litre of fluid in a day. Coolant level has not changed since new. It has to be diesel !!! 
Unless ford has invented the perfect engine and it creates oil from air I think I have some fairly major issues....
Has any one come across this or have any ideas truck has 21000 km's

I follow threads regarding the making of oil; and they have been very few for this engine. I noticed you only had three posts so I searched to see your other post which I pasted above.

Do you have a bunch of oil sample containers?
I would be pulling an oil sample every week, put it into 3 containers (labeled and sealed).
Once can be given to Ford engineers for testing.
One for your own testing.
One for safe keeping.
Is this condition consistent with a DPF regen cycle stuck on / or activating too often (from the idle)?

Dealer has sampled, but has not disclosed results yet, due to x-mas holidays, I am also doing my own samples however did not consider keeping one for future use. Thanks for the tip.As far as the regen with the idle time, unusure, It appears that my truck falls into the severe duty catagorie, requires service every 200hrs , computer should take idle into acount and notifie of service sooner. Apparently this is not working. My big concern is the diesel in the oil.... What is it going to do to the crank bearings etc. will it be washing them out ????

Not good news?
Did you see my post about PetroCanada Duron-e oil?
It is suppose to be compliant with a "forthcoming" oil standard, the much delayed (and further delayed) PC-11 oil to replace CJ-4.
I would either use that, or another PetroCanada product with a similar verbiage.
It comes in a dino and synthetic version, and is suppose to be absolutely fantastic for Canadian conditions.
Oh.. what little I gleamed of PC-11 (which is hush hush) is that it specifically address the issue of oil dilution both from DPF regen, and also from biodiesel.
Go to the 6.4 forum, and there is talk that several cams got replaced (lubrication failure) and that is all the evidence I need.

I'm in Sask Canada, and my truck has had the NOX sensor replaced, and the light stayed on for 3-4 days after. The dealer wasn't sure what else to do but bring it back and they would do some pin-point checking. Well the night before I took it back, while towing a 10,000lb trailer, the light went off and hasn't come back on.
It's been 10 days or so and still no light. Mine also gets a lot of idle time, but the dealer did the elevated high idle mod to it so it can purr away at 1200 rpm. I've never checked the oil so I have no idea whether the oil level is increasing.
Your in northern Alta, where its also cold. How does your high idle work when its -20 outside after a cold start. Mine does not kick off when I press the brake pedal like my old 6.0 did. Kind of like driving a vehicle with a carb with the choke stuck on, in gear, tach reads 750-800 rpm. Put it in park or neutral and goes back to 900-1000 rpm till it warms up. Ferd has no idea on this either.

Bet you it is a sensor calibration issue.
Suggested hypothesis:
The software bingo at Ford or the contractor wrote the NOx calibration routine for room temperature, without doing a different calibration routine for when ambient temperature went below a certain point (e.g. -20C).
At that point, the sensor failed to calibrate correctly regardless of,
a) no problem with the NOx sensor
b) how many times the NOx sensor is replaced.
Alternative / other possibilities:
Error in the sensor heater routine / bug that somehow cause the heater not to be turned on.
Or:
Problem in wiring of heater circuit (that should have been detected).
Solution:
a) run the vehicle at extremely high output, causing the sensor to "heat" properly and then either automatically or manually trigger the calibration routine
b) take the software writer for that module out behind the barn
c) rewrite the code module to include a cold weather sensor calibration routine that uses the signal curve for "below xxx temp" subroutine.
d) contract the software writing out to India (if the problem is they have too many Chiefs and not enough Indians).
Or, alternatively, pull it back to Ford USA if the problem is the opposite.
If a Ford rep or Engineer / Tech / employee is watching.... please let me know where to send the invoice for this.

when i ask why it won't idle up as previous models to keep heat in engine. I had manual override on my 2005 6.0 would idle up to 1250 and stay there, this also helped stop cokeing in the turbo. Is this an option available for the 6.7??

Dealer is supposedly in touch with ford engineers and they think it is a software issue. In the mean time comment from dealer was .... Drive it you have warranty !!
Great very reassuring. 
I would hate to do more damage than required to the engine if getting fuel into oil. Ford may have a different opinion when I am fighting for warranty down the road with issues related to washed out oil 
I beleive that the issue could very well be as you mentioned .. no one thought that these trucks may run in cooler climates, i don't know the ratio of trucks in Canada versus the USA but i beleive that we are fairly high percentage of ford's overall sales. Think they might consider and be prepared for options for our climate

I am willing to bet it is software.
Show the dealer / Ford Engineers the post and see what the dealer says.
The trucks are suppose to be designed to operate right down to -50 on validation... but that doesn't mean every bug is ironed out.
The problem probably occured because somehow, your truck triggered a new calibration for the NOx sensor, when they are suppose to be calibrated from the factory as they ship it.

Reminds me of the Mars explorer that lawn darted into the planet. It was designed with miles and feet and programed with kilometers. It didn't try to slow down till it was to close to the ground. Engineers....go figure. :-)
