campcop Report post Posted March 17 It sounds like the DPF needs to regen. If it starts does the idle jump up? If so, it’s in regen but it sounds like you’l have to force a regen which I think only a Cummins tech can do. Wish I could be of more help☹️ Share this post Link to post Share on other sites
elkhartjim Report post Posted March 17 If the regen light is on don't turn the engine off. If its driveable, i recommend taking it out and driving it like you stole it for at least 100 miles.. With only 19,000 miles in 11 years, it probably needs lots of maintenance done. Diesels are designed to be driven. Share this post Link to post Share on other sites

elkhartjim Report post Posted March 17 I cruise on the highway at 70 mph and 1800 rpm's. It should regen at 1700 rpm's. Share this post Link to post Share on other sites

elkhartjim Report post Posted March 18 If I'm understanding you correctly, the transmission is in neutral and you can rev to 1700 rpms. High idle on my 400 Cummins is about 1000 rpm's. What happens would you put it in gear? Does the power (RPM's) drop? If this is the case it could be a clogged fuel filter or clogged DPF. Share this post Link to post Share on other sites
campcop Report post Posted March 18 How close are you to a Cummins Service Center or authorized dealer? it could be a clogged DPF or a sensor, but the only way to tell is to put your coach on a analyzer. With luck you may be able to get a Mobil tech to scan for codes and if necessary, do a forced regen. as Elkhartjim said, it also could be a clogged filter causing the low rpm’s and check engine light and with only 11,000 miles on your coach, it could be clogged. But I don’t think that would throw a DPF light. There are several DPF icons, can you take a picture of the dash? Have you checked your onboard diagnostic screen on the dash for codes?

elkhartjim Report post Posted March 20 I remind you, don't turn the engine off while it is in regen mode. I'm glad you were able to resolve the issue. Share this post Link to post Share on other sites
