AdBlue service cost
My E350 BlueTEC is approaching its one-year mark, so it needs to be serviced soon. Seeing as this is a lease, I have to take it in to the dealer. Anyone have an idea as to how much the AdBlue refill will cost above the standard Service A price? Do they charge by the liter of AdBlue, or is a set cost? If it's the former, then I may as well dump a jug of DEF into the trunk beforehand and save some dough.
Thanks!
I chose the DIY method which was easy the second time I filled the tank




Am I missing something ? I have never serviced any of my leased cars at the dealership (including my Bluetec). Am I obligated to do that ?
I added Adblue by myself. Easy as windshield fluid. Got it here :
