My truck has 1600 kms on it and I got the "1600 km range left- Def warning". Obviously the dealer never filled the tank upon delivery in Feb.. I phoned them and they say that they never fill the DEF fluid due to freezing so they only put in one jug, bigger size. I asked if they then would fill it if I drive there and they said that I would need to pay for it. ($15 a jug) I thought I read on here that people were getting DEF refilled as part of the 2 yr maintenance. If so does anyone know where I can get that in writing? The dealer is playing hard ball...its a small issue but if it is supposed to be included then I want it done right.
