    Having a strange issue when I try to do a required regen. Sometimes the idle will jumble over the place and the temperature won't get hot enough and the regen won't complete. If I shut down for 20 minutes to an hour it'll sometimes work, sometimes it won't. Any ideas??

    Clean the (7th) injector in the exhaust pipe after the turbo. Some soot can build up and not allow the diesel to spray and mix in the exhaust.
    I had to do that on my 2017-DD15. I tried to regen for couple hours, exhaust wouldn't get hot enough.
    Called Freightliner mechanic. He had me clean the port and it only took 45 minutes for regen.
