2014 E350 Battery Drain
Got a new one. My E350 4matic is pulling about .3v and won't go to sleep. It was at the dealer for over a week and they couldn't replicate it. Got it back, battery died overnoght, pulling .3v again. Dealer has it for another week and can't replicate. Go to pick it up today, battery is dead. So, they had it inside the shop for the full first week without issue. This last week it was inside until a couple days ago. I don't park in a garage, so it has something to do with parking outside, either heat related or maybe a light sensor? Anyone ever experienced something similar?
