    Ok I'm so confused why they installed the awning kit in the first place if instead of replacing nox sensors again. So could you tell me how the derate process progresses. I just left dallas freightliner, and now have to figure out how long to get back to them for the same codeso_O

    Initially they said it was the one box and called back later saying awning kit was the solution. So this 1box is that the DOC/SCR module itself?

    Unfortunately the Detroit system has the DOC/SCR built in as an integral part of the One-Box assembly. Only the DPF filters can be changed.
    I wonder if there is an aftermarket solution by now?

    Awning kits are a bandaid put a new one box save you lots of down time and money in the long run (IMO)
