Interesting they revealed that to you. Usually they say "your car is the first GM's ever heard of this issue" even if there's a database full of cases. At least they are being forthcoming. It is a great sign that they are doing this with your car - it shows they really are trying to get to the root cause and fix it. That makes me feel hopeful.
The sample size in this poll is much lower than that, but of the people reporting, it looks like more than 50% are having an issue. That being said, the poll specifically states over 1000 miles from the time of the recall, so that may play a role as well. I think a much higher percentage of those 2000 cars will eventually develop the P11DC.
I confirmed with my dealership they did reset the fuel trims. I've so far had several CEL and one "Poor DEF" message.
The service manager chatted with the tech about it. It's a small dealership with one diesel tech and me being the only CTD they service, so the combination of the conversation and checking the records confirms it.
****, well the thought was solid up until that. I feel like there has to be something that causes some people to have repeated issues, and others to have none.
Thanks for the info. I was due an oil change, while I was in there I tightened the intake clamps. (Based off of how tight mine were I can see how some might say they were loose. I think they are just torqued to a low tourqe spec from the factory maybe 12-15 in lbs. I would say mine were "snug" not loose. But I tightened them regardless). My CEL is still off from when I recently cleared it. I have decided not to replace the second NOX sensor if the light comes back on I am just going to continue to check and clear the codes as long as nothing new comes up and Fuel mileage and drivability remain unaffected it's a far cheaper option.
Hope this is the answer for yours and others with the CEL after recall
Thanks for the update. That's interesting.
As far as mine goes, I've seen less soot buildup, even with the CEL on.
