Wait you pulled the ESS's orange service disconnect and plugged it back in later and it still drained significantly in that time? if yes, you have an serious issues within the ESS.
I looked at your older posted ahr.log, bricks looked fairly close to each other, can you post a new log?
Yes, I pulled the ESS's orange service disconnect. It was to make sure the battery would not drain anymore, I hoped....
I'm located in Norway, temperature is maximum 20C these days. Thanks for the battery advice, the cooling pump seems to run all the time. Can that drain as much as 200 Watts? If yes, that could explain the 5 kWh per day drain I saw before unplugging the orange service disconnect.
I try to be very gentle with the battery (don't run cooldown though because I haven't the latest firmware on the OVMS yet). But this summer I rented out the car to a lady, and unfortunately the log file is missing some of that history.
During that rent, the brake pump was full of water and had to be changed because the lady didn't have enough feet-power to brake without this system working (the Top Gear also had problems with that...). Do you think it was cleaning or driving through deep water that caused this?
Perhaps water has entered the battery as well? I once got an error message indicating some error with the battery insulation, right after I got the car back about a month ago, but haven't seen it again.
For flipping the pump Tesla Service Oslo charged 1570 USD (I found the same vacum pump listed on the web for less than 500 USD and I think it is very simple to change it). I told Tesla service for the fifth of sixth time about the battery draining problems I have had for years, but they didn't have time to look at it and asked me to get back for a full check. For $200 per hour, which is what service charge here, I'm not looking forward to that.
This is the latest log file taken two days ago, right before the orange plug disconnect:

From 2013, note the 100 % SOC decreasing very fast at the beginning of the lower plot and the ESS temp going crazy at the end of the upper plot, please explain what is going on:

The car is now charging. I will try service mode and contact Tesla Service Trondheim. Thanks a lot for the valuable support!
