Chevy Silverado 2008 2500HD Diesel Engine Power is Reduced
I'm new to the diesel arena, my brothers both drove diesel trucks for years and loved them. I finally traded in my gas 1/2 ton and bought a 2008 Chevy 2500HD diesel with 50k miles. I've had this truck for about 2 weeks and thoroughly like it, it's a beast. However last night I hooked my 20' trailer up and started to go down the road. About 10 minutes into the trip I noticed that my truck had no power, I looked down at the dash and saw a "Engine Power is Reduced". I was able to get ahold of a service department minutes before they closed, they said that the particulate filter was plugged, that I need to drive the truck for 15 minutes at 30mps and the truck will do a self cleanse. I drove for 30 minutes, no improvement. I swapped out the fuel filter this morning and went for a drive. The first 2 minutes were normal, then back to the engine power is reduced. I'm stumped... any tips? Thank you, Damon

any codes? codes don't aways make a CEL
dealers can force a regen with the tech 2 or you could get the exhaust temps up yourself. you could do this by running the engine hard for a while, pulling a trailer on the highway, driving at 30 mph for, not 15 min but 30 or more etc.
others may have better suggestions as i dont own a truck with a DPF so experience is lacking in this department

08 duramax
I have an 08 Duramax with the LMM and on the dash display it says "Engine Power is Reduced" it wont drive over 5 mph! I had a code scanner ran on it and all the codes were P0101, P0102, P0571, P0678, P0113, P0299, P0546, and P0244B. Please help me figure out what these are and how/what I need to fix them ASAP!!!
