They just did the EGR recall on my truck and it started throwing EGT sensor codes. It was a pretty clear cause/effect relationship, but I'm VERY VERY wary of my dealer. They have a $150 "diagnostic" fee, and I'm afraid they're going to try and weasel out of this being covered. I'll be stuck with a broken part and still have to pay them the $150. Has anyone had any warranty-covered parts fail and replaced under warranty? Did you pay any bs fees?
