    Company truck that I drive is in the shop and they are replacing the def system on the truck.
    The thing is 9yrs old but just 200k miles. It's a DD16 but is it normal to replace the system ?

    Depends on what happened. A blown turbo or a dpf filter/SCR getting contaminated would require a 1 box swap at a minimum. Electrical failure, contaminated def, lots of idleing and no maintaince. Sensor failure causing parts to be cooked. All of those would cause extensive repairs needed.

    As for normal. At 200k? Not really. That means something broke or failed.

    200k miles doesn't really mean #### if it works every day. Bet its got over 20,000 hours on it over those 9 years. In that case I'd say its due for some emission system maintenance.

    That’s about right, I was around 700k(miles) and around 20k hours when I had to replace the system(burner and dpf).

    You sure it’s the def and not the one box?
    Generally the only time the entire def system is replaced is when someone puts something like diesel or gas in the tank.

    It's been two weeks in the shop and the one box has been replaced along with a list of sensors and parts .

    Excessive Idle

    Super Truckers and Image...

    Gotta look good when your sleeping in the Pilot at night.

    Need to idle that truck, park where you block everyone in and leave your high beams on in the parking lot.

    Make sure you stay there till 10AM with the curtains drawn, blocking both the scale and fuel island.

    Is it a PTO rig?

    I run one, spent a bunch of money on it.

    Go buy a better used freightliner from Doggett in Little Rock, AR. Used Maverick Fleet truck. 80K will get you used midroof 400K miles, and EW5 warranty.

    Arrow will #### you over on warranty. Go to Doggett.

    By the look of his profile pic it doesn’t seem like a Maverick truck would be a worthy replacement for a specialty truck that has only seen 200k miles in 9 years.
