That's why I thought it was a bit peculiar. Of course I only have filled it from ultra-low-sulfur taxed highway diesel pumps so i would have disputed a contrary indication. The fix included reprogramming as well as injectors.
The vehicle got towed in on a Wednesday evening and was done Monday afternoon. No weekend work.
Yes under warranty. I briefly saw the "if it's throwing this series of ungodly codes, do this" sheet before it disappeared under the counter at the dealership.
I had this message at 15k of running beautifully, and went limping. 150 miles from home. Truck would not make the message go away on its own by off/on cycles as suggested in manual. I had it towed to where Chrysler would take it, fortunately in the town where I was spending the night anyway...
