How To Manage the DEF In Your Diesel Sprinter Van | Outside Van

Did you know your diesel exhaust fluid needs to be monitored on a regular basis, just like your oil or windshield fluid? Check out our handy How-To video to learn how to manage your DEF fluid, where to buy it, and more.

Outside Van is not responsible for damage resulting from improper winterization. This serves only as a guide to basic procedures.

To add more DEF:
1. Turn off your van.
2. Pull the hood release latch located to the left of your brake pedal.
3. Close all vehicle doors so ammonia vapors can't enter the vehicle.
4. Press the lever under your hood to gain access to your engine.
5. Locate the fill port. A majority of the time the cap is marked. Turn the cap counter-clockwise to remove.
6. Fill the tank via the filler neck until the DEF level can be seen in the filler neck. Use a funnel for best results.
7. Once finished, replace the filler cap and turn clockwise. You will hear a click when the tank filler cap is fully closed.

I don’t have a diesel vehicle, so this was educational and entertaining 👍

Sounds as easy as filling windshield wiper fluid. Thanks.

Thank you for sharing. How many miles i can drive a sprinter after the light is on?

[vintagesportscards]

How about draining? Looking at a 2017 with only 4000 miles. Probably original def in that tank. How do I flush or drain it

[Milner_THX]

Please look at the camera guys!.. this off camera gaze is silly - looks like listening in to a private conversation.. brilliant vans btw 😬👍🏻

I have a question, why is the oil missing when traveling? I don't have smuggling or fumigation. I have a van 2021

We call it ad blue here in the UK I believe

DEF is much cheaper at the pump than it is in the containers. I would always try and use a truck stop where they use high volume in order to ensure freshness

[changanga]

I bought a used 2008 model and it is diesel But i dont see where the DEF is !!! May be this 2008 year don't have one..

Don’t ever trust the level indicator in dash.

[CupidinColorado]

I hear not to use def older than six months…?

[CarsSlavik-mtrt]

Why would anybody want to mess with an extra cost and extra maintenance it sounds like a nonsense to me .
is that why they are so cheap compared to other vans?

[firpofutbol]

Kinda weird when the guy doesnt even look at the camera.

[jaysonbird]

8 starts remain.. am I looking down a money pit?
Terrible system

[duartepaintinghandymanservices]

My advice, stay away from a sprinter, I have one and only had it for about 5 months it only has 63k miles and been at the shop 3 times and each time it was over $1k, should have went with a ford or dodge

Not "Potential" It WILL go into limp mode!! Amazon, FedEx etc all found out how awful the Mercedes DEF system is.

[bobdrake]

FakeFill on your vid, DEF is nasty and should be sold in a better size and type of dispenser. The cost should be included in actual cost per mile

[jesualdotavares]

Buy electric or gas engine vans.
About DEF. Here is what you do.
Buy a can of gas, throw it in the van and light up a cigarette 🚬
