Does your paperwork show the number of gals for each DEF fill?
IMO All of us (35d owners) need to require that our dealer tell us how much DEF was used to refill the tanks. That is the only way we will be able to get a handle on the usage rates for the 35d. It pretty obvious that (at least some of) the dealers are clueless about this issue.

Well, the invoice says they used 1 83-19-0-440-158 diesel exhaust fluid.
Also says filled both tanks. Says they checked fluid level via ISTA.
Does not state quantity of DEF used.
Next service visit will be in about 3k for oil change. Will ask what quantity DEF they use then. It won't be long for 3k to happen.
Hope I don't need DEF filled before then.
Will keep everyone updated.
