My 2015, currently stock. Truck with mostly city driving is doing a regen cycle from 109-154 miles, and I always get the truck up to operating temps before I shut down. No message, of course because stock does not display anything. But I have a BlueDriver OBD2 set up to tell me when I have Active/Passive regens and also a PID set up to tell me the average miles between each regen, just FWIW... T-BirdFactory tune = active regens every 75-150 miles on average. GDE tune = active regens every 750-1000 miles on average.
