This relates to my 2015 85D, which has been connected to TeslaFi since December of 2018. For the last year, or almost a year, I've been seeing high vampire loss and TeslaFi has been reporting few and short sleep periods. I've been attempting to track this down and have been through the TeslaFi website's recommendations for TeslaFi to reduce polling etc. Note that I don't believe this problem existed until sometime last year.
I've also noted that if the car is left plugged in to my Wall Connector, I can hear what sounds like a small fluids handling pump running continuously somewhere near the front left wheel. The charge can be complete, but the pump still runs and will run until some random period after I go to the trouble of unplugging the Wall Connector. THe pump will run for days if I don't unplug the WC! My guess is that the pump activity is related to managing temperatures in the battery pack, but why it continues after the charge is finished... or why it's needed at all for 40 amps in a room temperature (or cooler) garage... I don't know.
When the pump is running (or the car is plugged in), the car doesn't seem to sleep. If I leave it unplugged, sleep behaviour seems to be appropriate and vampire loss drops.
I think there's an issue with the pump control logic and have been trying to get my Tesla service people to take an interest in the problem since last fall. No useful help from them to this point, in spite of doing a factory reset at their request, etc. Now they are telling me that TeslaFi is the problem and I need to uninstall/deactivate it before they will waste any time digging into the problem.
This seems like a chicken-egg conundrum. Is the pump keeping the car from sleeping, or is the car not sleeping because it won't turn off the pump? Or is it something else entirely? Is TeslaFi involved?
One other clue... If I set a time to start a charge, it seems like the pump will shut off after the charge completes. If I set a departure time, or set nothing, the pump runs.
Has anyone seen this problem before, whether associated with TeslaFi or not? I can disable the account for a while I guess, but it would be nice to be able to tell Tesla this isn't the problem, with a solid reason why. I can't see why any polling from TeslaFi (which is very little, since I followed their recommendations) would prevent a pump from shutting off (that probably shouldn't even be running in the first place).
