My last work truck that I was assigned to at the electric utility I retired from was a 2008 F450 with the 6.4 diesel. The nature of my work required extensive idling, most of the time parked at the curb while working in an electric splice box. The truck, sitting close by and idling would go into a regen cycle and the smell was terrible, just about make you sick. They finally got with Ford, and Ford engineers came up with a modified program for the regen that would only allow it to function while in gear and driving. The info screen would come on the entire time the regen was going, and would tell you to continue to drive until complete. Worked for me, occasionally a little extra overtime was needed
A Ford factory crew went around the entire utility and reprogrammed all those model trucks. Don't know if this was available to any other owners.
