Truck doesn't tell you it's in a regen. Couple things you can do. Turn on your filter percentage via FORscan or a dealer visit. When your fuel mileage tanks is another indicator. As far as how often more in town driving will cause your truck to go into regen vs highway miles. Lastly I run a OBDII connected to a tablet and run FORscan lite app and it does tell you when the truck is in a regen.

I added the dpf % screen with forscan, and turned off the annoying double honk if I get out of my truck with the key in my pocket while it’s running.... I’m just really surprised I’m only getting 200 miles between regen though

It is not possible to have traveled 600 miles without a regen occurrence.
ford's strategy is to regen every 500 miles, needed or NOT...regardless of the % filter full.
below youll see the DPF Filter is only 33% full, and REGEN is ACTIVE...because its been 497.1 miles since last regen.
To the OP - you can use ForScan Lite to monitor regen (activated) status - among other things.
Regen Activated, DPF Filter 33% Full, 497.1 Miles since last Regen

This is interesting. The only indicator I had of a regen was the fuel economy tanking suddenly after it had been boringly steady at 15.7. I’ve checked the dpf percentage periodically and it was steadily increasing. Maybe i just happened to check it at the right times to never see it lower than previous before now?
I don’t have forscan lite or an adaptor yet but this is one of the many reasons why I do want it.

other than forscan lite on an android or ios device - the only other indication I know of is the sudden drop in MPG

Thanks for the info. Is it possible to have a slight smell. It was at a time with about 20 km on a secondary highway during snow conditions. I attributed the decrease in mpg to 4x4 being activated. But I did recal a bit of a smell when I exited the truck.

As was said above, a regen will happen when on of the three conditions are meet (G/L soot exceeds 8.38, DPF % reaches 100%, or 500 miles since the last regen), AND the engine is at normal operating temperatures (generally oil and coolant above 185)
It is not possible to have gone 6000, or even 600 miles without a regen. The trucks are just set up to NOT give much indication of when it is happening. Just because you did not notice it, does not mean it did not happen.

This part of that statement is not 100% accurate. The only way to tell the regen is in process on a truck, as configured from the factory, is the drop in mileage, either instantaneous, or the 30 minute history. Once you start bringing in other equipment, Android or iOS devices can run forscan, and output the information. Other dedicated devices such at the Edge Insight can also tell you when a regen is happening as well.
