DEF tank on newer Soleras

[Slow_movin]

I have a 2015 24R ready to pick up from the dealer next week and would like to know how much DEF the new models hold.

I have a 2013 24S it takes 3 gal. of DEF, Problem is you have to fill it up slow because you can't see the fluid level in the tank.

Is your DEF tank under the hood of under the coach? My 2011 24S the DEF tank is under the coach and has a door to access it and requires a special tool to unscrew it. It holds approx. about 5 or 6 gallons of DEF.
The tank in the engine compartment is probably where my DEF filler will be. Just want to know how much it holds.

My is under the hood next to the radiator. Best of my knowledge that is the only location on mine. One thing too, is I have a 2013 Solera but the Sprinter chassis is a 2011 or 12.

Just topped off our DEF tank with 2 gal. at 4400 mi. Ours is also under the hood on 2015 Solera 24R on the 2014 chassis. We bought a 2.5 gal DEF container at WalMart for around $12. Be sure to pour slowly with the included and attached funnel and you might also put some disposable shop towels around the filler area and a bucket of water just in case you spill some. Took 5 min.

The filler is under the hood, but I think the tank is down further. If you cover the small black air valve when filling with the DEF nozzle from the container, you can control the flow and stop it when it is near the top of the filler.

Thanks to all...you have answered my question...

Just for reference, MB transitioned the def tank from the passenger side storage area (2011), to being contained on the Sprinter chassis under the hood, in the engine compartment (2012) between the 2011 and 2012 model year.

To determine exact chassis year, you need to look at your VIN#, of which the 10th position determines mfg'd year. So, as a reference the letter C = 2012, and as the alphabet increases, so does the chassis mfg. years' date. The capacity of the def tank for 2012 is exactly 12 liters. I'd assume that continues to be the same for the subsequent years.
Hope that helps.
