I have a 2019 Ram with a 6.7. In January of this year CP4 went out, 1-month at the dealer before they replaced the entire fuel system and put in a cp3. Since this work the truck is performing a regen every 50-100 miles. I can hear the difference in the motor when it regens and the DPF monitor...
im getting a code P0403 and P0406 says EGR valve, easy fix right? (arent they all). Only I go to dig into it and well no EGR valve.. I can't find information or videos showing a second type of EGR set up? can anyone assist?
