I'm a big believer in idling causing issues also. I rarely ever idle and knock on wood have had great luck with both my dd15's.

Oops. I'm in trouble. Lol. I've been idling my truck every night since my apu went out. Can't ever get it in to be fixed. I guess this has been going on for about 2 months now.

I idle my truck every night if needed to stay cool as my Idle free system has worked 5 hrs total in the 9 months i have had this P.O.S and thats with being repaired 3 times and losing 7 days, Dumping this junk in November

I don't believe either vendor looks at idle time. I know that Paccar does not, but I can't recall whether or not Cummins does - however I don't believe so. If Cummins did look at idle time it would be because of a major, major repair. Otherwise they never even see the ECM images and won't get to see the idle % regardless.daf105paccar Thanks this. -

The advise to just run with it and see if the code goes away is bad advise. If the doser is blocked the ECM will not turn it on. If the doser doesn't run the system will not generate enough heat to regen the DPF filter. It's just a matter of time before you get the parked regen request light. But a parked regen will not work either, for the same reason.
If you want to invest in a USB-LINK and a copy of the DDDL software there is a Doser Purge service routine you can try. That may make the fault code go inactive, which would allow you to force a parked regen. That can sometimes clear up a clogged doser valve problem. In your case though I doubt it since you've already installed a new doser valve once.
Twenty six replies on this thread so far and we still don't know what the exact fault code is.Home_on_wheels Thanks this. -
