This 35d is the first one this dealer has seen. I'm sure they still learning how to fill it. I'm being patient and not going on any long trips.

And here is what I think happened to k80jr's 35d...
<WAG>
12k - BMW tech flushed and filled the small DEF tank. And the tech left whatever DEF was still in the large tank at that point.
18k - The remainder of the DEF in the large tank was gone and the small tank was down to the warning level. Once again the BMW tech only filled the small DEF tank and didn't touch the now empty large DEF tank.
19k - The small DEF tank dropped to the minimum level (roughly 1/3 full) and triggered the DEF warning countdown again. Hopefully the comments "Also says filled both tanks. Says they checked fluid level via ISTA" means that this time they did flush and fill the large DEF tank
