Random question, do you happen to remember what the high/low temps were outside the day that this happened to you?
Same thing has happened to me a few times, and the last time it happened when the egr was turned on with the DPF on by coincidence. I took it to dealer and they replaced the EGR valve. Each time it's happened, the high/low for the day is spread out by 30 degrees and it changes quick then my EGR sticks.
The first time it happened, I and 2 other members on another board had same issue one the same day with the SCT on with the EGR on. SCT told us to tune it off, and never came up with a better fix.
