I just drove my 2009 lmm 2500hd from Illinois to Colorado pulling my 24ft enclosed trailer (1000 miles). My best guess was about 20k lbs gross. The truck is bone stock except my edge legacy. I always monitor my dpf cycles and soot levels. The truck normally begins regen around 44 grams of soot. I was producing so much soot that I was in regen mode almost the whole trip. Once I hit Colorado, I could barely keep the soot under 75 grams. It got so bad that the soot got all the way up to 95 grams and put my truck in limp mode. I had to clear the CEL and unhook the trailer to get the soot low enough to pull the trailer. Truck only has 70k on it and the edge was only on level 2. I am also noticing that my truck seems to be producing soot more than normal now as well. Sorry for the lengthy post. Does anyone have any idea what kind of issues I could be fighting here? Dpf? Fuel? Edge?
Thanks!
Thanks!
