Another regen question
My 2019 just has little over 12,000 miles now,and has always gone to 0on the dash after a full regen.thus past regen went to 20 and stopped while still on interstate. Does this sound like a possible problem to anybody.

No problem. I have never seen a full accounting of all the parameters for the regen. I can tell you that it doesn't work the way you or anyone else thinks it does. That's because there are way too many "if/else" conditions to know everything. if you fall outside of the desired targets and the computer seems the regen is sufficient, the computer calls it good. I normally go to zero if I keep engine speed above 2k RPM, but if I have to stop or just slow down, it might stop the regen even when I get back up to speed. My last stopped at 30-percent just because I came to a light. It wouldn't go back into regen no matter how fast I went. Another time, I was in regen and it got to 70-percent when I had to park. Got back on the highway a couple hours later and it started back in regen. The damn computer is going to do whatever it wants to and it doesn't pay to try to worry over it or figure it out.

I need some help too. I have a 2017 f350 6.7 - I asked my dealer - spoke directly to the diesel tech who does the maintenance oil changes etc about “downloading” the regen notifications within the truck and they said I don’t need it? I asked about what if I turn the truck off during an active regen and he said it won’t hurt the truck. That seems to contradict everything I’ve read here. Anyone have any insight?
thanks

The technician was telling you the truth. Regens are done behind the scene. If you were to get to the point where you were on the threshold of doing harm to the DPF, you will get a warning telling you to drive the truck to clean the exhaust filter.
I suggest you read your owner's manual to fully understand your emission systems. It's not like it's a long read. Don't read anything into the text. One thing you would notice is that nowhere in the text does it read that you have to burn down the filter to zero or anything like that. One reason is that without the DPF screen, you wouldn't ever know what percentage it was. The other reason is that a successful regen means it's not at 99-percent.
You don't need any additives. Try to be more like those owners who don't have a screen telling them something that's going to happen regardless of their concern over the event. In other words: Just drive the truck. Don't worry. Be happy.

The dealer can activate the screen. Again, the tech is right; You don't need it. But you're a customer who expressed an interest in having it. Maybe the dealer could do something to accommodate your request. Promise them you won't be bothering them about what the screen shows you since you took a pledge to Don't worry, Be happy.

If I go down a hill or stop for more than a few seconds the regen will stop.
I have also found that the % can Chang slighty if the engine is stopped and is off for a while.
I really think this is one of the reasons Ford doesn't put the DPF % screen on most trucks, it just makes people worry too much.
I also feel the % is an arbitrary number and doesn't nessarnessarly mean that 0 is no restriction at all and 100% means completly plugged.
I thinK is is a relitve number to what is considered "empty" and "max allowable fill".

I've found if I'm low on diesel and get the "less than 50 miles...refuel now" message in the middle of a regen, the regen stops.
Had a regen begin on the way to fuel up and thought I would just take a round-about route to the gas station and let the regen complete. Got to 95% and the "less than 50 miles" message appeared. I drove around for awhile, but the regen went no further. Fueled up, drove a bit and regen went back up to 99%, continued on and it started again and completed.

There is a lot of truth to that. To me, I just bought the 'financially irresponsible' truck I wanted, which is way overkill based on what I realistically needed. That being said, ear to ear grin every time I hear that diesel engine fire up or watch that boost gauge climb.
