I have a very high soot code on my 2009 Cascadia, 2009
my truck shut off because of soot very high code. I tried to do a parked Regen but after 2hrs it never completed, so i took it to a shop and had the DPF filter replaced. when the shop tried to do a regen to clear the soot very high code it still wouId not finish, then when we notice the temp stop rising. I have read conflicting things concerning how high the temp need to be before the dozer starts, we did a dozer purge test and everything looked fine, so remove the dozer and found the pipe it mounts to clogged so i cleaned it. i prefomed a regen again and the operating temp is still too low. wont get pass DOC INLET 439, DOC out 450,DPF 450. I did notice that the fan runs the whole time its running the Regen and I didnt know if that was significant or not. the EGR has been replaced in the last year. Took I to Freightliner and those guys told me exactly what I already knew, he first told me the doser stats at 700 temp then he told me I probably needed to replace the doser because operating temp is stopping around 400 huh? help… read more
