w212 battery drain 2011 e350 bluetec
battery draining started in august. dealer indicated a faulty starter then but that did not help. then came a new battery followed by a new alternator in the fall. better over winter, but now car does not turn over at all. any ideas? 49,000 miles

IIRC folks with early model W212 complained about battery drain and it was linked to the climate fan running after shutdown to dry evaporator. Perhaps it runs too long and wears down battery. Solution was to program car to not run fan later on. Maybe that is one of the bulletins that konigstiger posted, but I can't tell.
