For the past few months, I've been having a phantom drain on my 12v battery in my 2011 Nissan Leaf. It goes dead after just under a week of sitting idle. I've monitored the voltage and it steadily drops over time (going from about 12.50 to about 12.20 in a day, for example). A current meter consistently indicates that there's a 0.19amp draw. The TCU is unplugged, and pulling fuses from under the fuse box under the hood does not help (though I have only tried the regular fuses and also haven't touched the passenger compartment fuse box).
Here's the weird thing. This always happens, and has for months. But when I took it to a Nissan dealer, it sat there for nearly a week and they claim it only lost a trivial amount of voltage (0.02v) in that time. I am just baffled by this. Why would it consistently drain at home, but not at a dealer? I can't think of a reason why they would lie about it (they're turning down work to fix the problem).
Any ideas for what could be causing this or why it might behave differently based on location?
Thanks in advance!
