On a 2010 35d w/ only 1690 miles and a correctly working DEF system, there are only two conditions when this should happen...
1 - The larger 'passive' tank was empty (e.g. it was never filled).
2 - The larger 'passive' tank was frozen.

So unless you were in sub freezing weather (i.e. <-11c for awhile) when the warning came on, 'All did [NOT] come up negative'. You and your dealer just don't know it yet
