    I’m sure a lot of people have gotten this code before, and I wanted to know if it’s worth going thru all the trouble and most importantly money/time to get this fixed or if it’s better to start looking to sell the equipment and get another newer truck. I’ve got a 2015 Cascadia Evolution automatic smart shift, and it’s a great and convenient truck, but this nox problem I heard is notorious among these Detroit engines. I want to hear your thoughts.

    Thanks,
    LongHaul53

    Piece of black tape over the light,,,I'm sorry, people have called me a troll for comments like that, nothing could be further from the truth. I really have no idea and can't for the life of me understand why you people put up with that junk. I get "Truck Paper" notifications all the time, there was a '78 KW W900, day cab, 400 BC , 13, and air ride, in great shape, asking $15g's. Why would someone spend 10 times that for a modern POS?

    Ya, it’s a catch all code for low NOx efficiency. It can be just about anything. I’ve had it since winter, mostly first thing on a Monday morning. I have Detroit Diesel Diagnostic Link, so I can eliminate some of the steps without going to the dealer. One of the early steps it said to replace the outlet NOx sensor as it was reading low. But that didn’t help.
    I did notice if I did a forced Regen the code wouldn’t pop up for several weeks. Which could be an indication that I needed a DEF awning kit. My DPF filters I knew were coming up soon, so I waited a few months for when the Soot full code came up. Which was only just over a week ago. I had them install the DEF awning kit at the same time.
    I’ve only ran the truck for four days so far, but its been fine so far. But I’ll know for sure in about a month.
    If not, then the inlet NOx sensor is the next step. And so on, trading off the truck does get tempting at some point.

    Thanks for the input! Is DDDL the software they use at the dealer when they hook up the laptop to the truck? How did you obtain that and how can I get my hands on that?

    Try doing a parked regen. Clears that catchall code for me every ####### time, even if the DPF light never came on. I'm running in a company-issued 2016 Cascadia Evolution for the moment

    Thanks, I tried doing it, but it doesn’t let me. Good thing you don’t have to put up out of pocket cash for the repairs. Thinking about switching to company driver myself.

    The smartest thing you've said. Reason I said a 1978, is they were so simple, and a horse is a horse. Don't poo-poo the old KWhopper, it will be running long after that Freightliner has weeds growing through the frame. I know I'm no help. Good luck, it's just not how I'd want to spend my off time. I think it's terrible a 4 year old truck is giving you problems.
