My truck has 133000 miles on it been in the shop for your problem they found the intake manifold had a softball size hole in it. The replaced intake manifold both fuel injector rails all the injectors found the manifold clogged with carbon deposits, cleaned carbon up and replaced EGR precooler and valve. Do not let them tell you it is a bad filter because the code signals a loss of electrical to the number one cyclinder ejector.
Get the insurance company check, buy the GDE compliant tune and I'll bet your codes will be history, and the truck will run better than ever!!!
My 2014 Eco Diesel Rain 1500 has had this issue for over two years and the dealer has done everything from replacing the whole emissions system (I mean everything) I have even had My DEF tank replaced and fuel injectors replaced. The finale outcome is they DO NOT KNOW HOW TO CORRECT THE ISSUE. On my end I've tried every Fuel Additive on the market, Different Gas stations and Truck Stops, Tried changing my fuel filter every 6,000 miles Nothing and I mean Nothing has worked. If someone ever finds a solution I would appreciate it, but until then I keep driving my truck (which runs great by the way) with the engine brightly glowing as I drive along.
I just picked mine up from the shop who had it all week and they were pretty stumped, I guess there was an update due and they also found that the MAF sensor plug was a bit loose. Honestly not sure how that would have happened but between updating and that they called it good. If the code came back they'd need a Star Case. Drove home and ran a couple of errands without issue, so we'll see if it stays clear.
