09 d13 idling problem

Did you try to use the pto , set the idle at higher RPM, maybe the idle is set @ too low rpm for outdoor temperature; I set it according with the oil pressure; @ 500-600 rpm my oil pressure is too low,( well I use synthetic), soo I rev it up around 750-800 rpm to bring closer to 60, if is cold outside even higher; But this new motors don't like idling;

 

Sometimes this is normal it's just the difference between having the egr open and closed it does exactly what u guys describe but it cycles at idle when the truck warms up it runs the egr more I don't think u have a problem any codes besides the nox code

 

It may be using less or more gph the computer is making a guesstimate there is nothing measuring actual flow .. That's why most dash displays are off compared to pen and paper a gallon plus a hour is normal on class 8 diesels

 

Hey! Have ever figure out what was the problem with your idle did like that? Mine does the same thing.09 820k D13 13sp. Did replace head with injectors couple month ago and that thing disappeared for a while. Now it started doing that again when idling. Appreciate your help

 

I have the same thing with my 2015 d13 455hp 550k , I shift

 

The reaction you describe is the warm hold mode on Volvo engine. Controled by the engine Ecu based on engine temp. The turbo position change and the engine timing to increase engine load to keep engine temp at a certain level. Ben
