    @ my 10,000 mile service they filled my DEF tank. It just read it holds 5 gallons.
    My def light just came on yesterday at 18,553 miles...

    The MB Training Material for the system says "1000 miles" from first warning until the countdown clock. The countdown clock is a "20 start countdown" designed to keep you from burning out expensive parts by making sure you can't run it out of DEF.

    That would leave me 447 miles short of my 20,000 mile service when the 20 start clock begins...

    Why the heck Mercedes couldn't make the tank 1/2 gallon larger and make Adblue refills fall on the service intervals is a disappointing oversight. :becca


    I think I might go pick up 3 gallons of DEF at the local autoparts store and throw it in the back and then run it until the countdown clock... just to satisfy my curiosity on whether I can make it or not...

    Assuming they are going to charge you the $10 per 1/2 gallon when you do the service I suggest going to a truck stop and buying 2.5Gallons for about the same price and making your service a lot cheaper.

    At least that's my plan. Light came on at about 8500 on mine and I want to have it mostly full again before I take it in for the 10k service.

    The amount of DEF used will vary considerably with the type of driving.............the tank size allows for normal driving plus a buffer....the ADV rider (driver) is NOT normal:evil:evil :lol3

    DEF is Diesel Exhaust Fluid. It's a uric acid-based fluid injected into the exhaust stream to modify emissions.

    Here's a stoopit question: does the truck know what's being injected? IOW will it inject about anything and think its doing the right thing?

    ...or does it HAVE to be DEF?

    ...and what happens if you don't run DEF in the truck?

    :ear

    It detects the def.. and the "purity" of the def.
    If you dilute it or anything it detects it and shuts you down.

    It won't let you run it without def... if you did manage to run it out you'd burn out some very expensive components in the 2nd catalytic converter (I've been told).

    Bummer.

    Is Ford pee the same as Benz pee?

    ...and are there emissions controls on diesels in CO? If you don't have emissions, has anyone successfully yanked the whole kit and kaboodle?

    Ford, benz, Chevy all the pee is the same. As long as it is ISO 22241 certified it is the same.

    The only thing that differs is how you put it into the tank. I know my chevy just has a filler neck like a gas tank under the hood. I buy the 2.5 Gallon bottles of DEF at the auto parts store for like $11.
    The Benz has a special filler neck I believe which means you need a Benz bottle or bring it to the dealer to fill. If I owned the benz I would just buy one original bottle from them and then cut the bottle and use it as a funnel or carefully cut the locking teeth at the base of the bottle cap neck. That way I could unscrew the bottle cap valve so I could refill the OEM bottle with DEF from anywhere.


    There are emissions tests out here in CO. My Chevy has an emission exempt sticker on the windshield but I think that is only good for 4 years. I haven't really checked that out yet.

    That's not possible, as it's an integral part of the electronics. There are sensors throughout the exhaust system that monitor emissions and the converter(s) to determine their functioning and re-generation needs. I've been told that the integrated muffler/converter on semi-trucks is ~$5K. I wouldn't be surprised if the Sprinter one is a couple thousand.

    You don't need a special bottle .. but if you have the special bottle it is impossible to spill it.
    You can just pour it in.

    Here's a video I made the first time I filled it:

    That's exactly what I was told about the semi version.

    If it's like automotive converters, the "honeycomb" is ceramic. And, yes. That'll crumble, if the casing is dented.

    My 6.7L Cummins exhaust, which includes the Catalytic Converter, a DPF (Diesel Particulate Filter), and a NAC (Nox absorbing catalyst), and muffler, retails for roughly $7,000 and is rated for approximately 100,000 miles. The Urea injection systems are slightly simpler introducing an SCR (selective catalyst reducer) in which the ammonia in the urea will react with the particulate and the NOx, however the costs are somewhat similar.

    No one said diesels were cheap... :huh

    :huh $7,000 after 100,000 miles? That's not just "not cheap", that's fucking insane. I'm so glad I have a year 2000 PSD. :lol3

    Cripes.. I hope the MB exhaust system goes further than that.. that'd mean I'd spend $42,000 in 600,000 miles on the exhaust system alone? I could buy another van for that.
