OK, after some basic research I'm lead to believe the problem stems from the post-combustion processes designed to improve vehicle emissions on the BlueTEC cars. There's some discussion that higher blends of biodiesel won't burn the same in these processes as pump diesel and this can lead to engine oil being dilluted with biodiesel which indeed would lead to eventual engine damage, not covered under warranty.
