2026 International LT: Should be bringing it home tomorrow.

At home getting the engine light checked out now. Third time for it to come on, plus trailer developed a small leak, so dropped them both off during my time at home.

Did your light finally become constant? Mine has been on the last week or so. Usually it clears itself after a couple trips.

No, it comes on for a couple days, goes off for a day or two, and then repeats the cycle. Being a DFP code, got it put into the shop to avoid it becoming a derate issue out on the road under a load.

Now, the dealership is baffled and don't know what to do about it. Waiting on Navistar to advise them.

I hope this is it for the new truck bugs. The computer actually thinks the DPF is missing from the truck. Very strange code.

That's odd. If I was wilding like you I'd want on it ASAP for the same reason.

turns out, it is a known issue and will be a programming fix. They haven't come up with the reprogram to fix it yet though. Safe to drive, no derate concerns, or at least that is what they told me.
