It is also flushing the DEF tank (the urea will crystallize after a while) and refilling it (since the Sprinter's computer only "credits" the DEF fill when it is completely filled up.)
Uh, no. I incompletely fill my DEF tank as standard practice so I don't have old DEF sitting in it.
When it gets low, the light comes on. When you put enough DEF in to get above the min level, the light turns off until you get low again.
