This year has been hell for me an my ecodiesel. I bought the truck new in 2015 and just loved the truck. I have the longhorn Laramie edition in Prairie pearl color with the brown interior. Still getting compliments on the looks of the truck. Had no major issues with it up until this year. Over the years had the number of recalls, had the cruise control go out but that was it. In February went on a 500 mile trip. Got almost to my destination and went to pass a car on a two lane road. and when I returned to my lane, engine started knocking. Had it towed to a local dealer in Georgia who after diagnosing the issue said they found lots of metal in the oil pan. Said I needed a new engine which they ordered. 4 months later the engine came in and it was installed. ($12,500) They never did tell me what went wrong, but I got a feeling the timing chain slipped. So got the new engine with a warranty and everything was fine. after 3 weeks got a check engine light. Took it to the dealer locally where I bought the truck and they replaced a sensor in the exhaust system which was under warranty. Last month headed out on another trip and got a check engine light again. This time was near the dealer that put the engine in and they forced a regen and it cleared the light. They said if the light came on again they only thing they could think of was that it needed a new Diesel Particulate Filter ($3500) Drove it another 1,000 miles and light came on with a code of P2459. Didn't want to spend the $3500 yet so After some research and good reading I thought I'd check the DEF injector which I presume could be keeping the DPF from cleaning during driving. It was crusted and the inlet to the DPF was also encrusted. I cleaned it and put it all together and then I got a code P2047. I purchased a new DEF injector and installed it, but when I tried checking it, nothing was spraying out of it, not even a drip. So I thought that since the truck had sat for 4 months out in the yard of the dealership that maybe the DEF fluid had clogged eveything up. I went over to the DEF pump at the bottom of the DEF tank and disconnected the DEF fluid line from the pump to the injector to see if the pump would work and maybe the DEF line was clogged. Nothing, no leak, no drip no pumping action from the pump.
So now I'm at a loss on what to do next. I can get a new pump and put it in, along with a new hose from the pump to the injector. If it do that do you think it will clear the P2047 and if I get the injector working would that have an effect on the DPF cleaning itself? Does the DPF use the DEF fluid as a cleaner to get the crud out? Any suggestions would be appreciated. I've been trying to clear this myself since the dealer would charge me a fortune to do the trouble shooting and then replacement.
