I had another thread about this truck and replacing those 5 sensors seemed to fix that issue. I put a new turbo actuator on the truck because I got a vgt fault ten times, that went away. The truck makes it about two hours or so before it requests another Regen.

If all that has been done, I would tend to think it may be either bad feedback data, bad delta-P sensor for DPF, or a bad/cracked DPF. Something it telling the engine that it is clogging up. Check the face after it starts complaining and see what it looks like.

Pull the DOC and DPF and have a flow test done and make sure it passes.

Maybe post a pic of the regen history and other data too.
