The issue started right after refueling at a tiny mom and pop station. I'm wondering if they got some crappy fuel or maybe some off road fuel?
That could be it. If the fuel wasn't low sulphur, it could cause problems. And since you you were on a road where you couldn't get up to regen speeds, your system went into LHM (limp home mode).
Thanks for the heads up about DPF (and presumably EGR) not being covered under extended warranty because they're considered exhaust. That didn't even cross my mind.
Does your engine have an EGR cooler? Just curious.
I was really hopeful The DPF Whisperer could have gotten everything fixed for you. ;)
