hello my 07 grand Cherokee crd is stuck in limp mode. after going through exhaust system and air intake replacing air filter looking for leaks and blockages, replacing egr, and elephant tube due to a crack . was still getting p0299 sent my actuator away to be rebuilt and still in limp mode. replaced turbo and actuator with new 0em ones all the way to the manifolds(all new gaskets). and then started getting another code for overboost contacted the actuator company who mentioned that they would usually say the actuator but seeing how its new he mentioned to replace the map sensor. now i am getting p2454 dpf under circuit. still waiting for the dpf sensor to arrive to hopefully fix the limp mode issue. gave it a new oil change and 6 new glow plugs. just wondering if anyone has any other ideas of what i can do to fix this if the new dpf sensor doesn't get it out of limp mode. possible dpf removal and cleaning? really like the jeep and am in it for so much money that i feel like i have to keep going any help would be really helpful. thanks, damon been doing the work myself and cant think of what else i can do to fix it. please help. thx

well i made an appointment at the local jeep dealer to have a forced dpf burn done and i am hoping it will get it out of limp mode and fix the issue. fingers crossed.
