Cleaning Exhaust Filter-Pull Over Safely Now
I ran into this situation last weekend on my 2008 F-450. It has 63k miles on it and never experienced this problem before. While I was going down the interstate, it went into its "Cleaning Exhaust Filter" regen. But after about a minute a "Pull Over Safely Now" display or something to that effect came on as well as the check engine light. I pulled over and the engine would not restart. Tried several times and finally after about an hour, it restarted but the check engine light was still on.
I traveled another 8 or 10 miles down the interstate when the same thing happened again. Had to wait another hour for the engine to restart (assuming the temperature had to drop or something). This time I was able to get of the next exit and head home (about 45 miles). Didn't know what to do so I thought putting it in Tow Mode might help and also when I saw the "Cleaning Exhaust Filter" come on, I hit the reset button on the display and that seemed to turn it off, unless the Check Engine Light overrides it somehow and I didn't know it. I did manage to make it back home.
The engine seemed to run normal and everything, but the Check Engine Light remained on. After several days sitting, I called my local diesel shop to schedule an appointment. When I started the engine, no Check Engine Light was on and it appeared to run normal, business as usual.
I haven't heard back from the shop yet, as they were running down a few display codes from the computer.
Has anyone experienced something like this before? Not sure if I should be any EGR or EGT sensors on hand and if they are a real mofo to change out.
