yes it's was 250 milDid you check the mileage when you drop off vs when you pick it up?

You keep saying "daily" but your calculations say "hourly." You're dividing by 24.Where I got the numbers:
The Tesla manual says that the battery self discharges at about 1% per day. Assuming the battery to have a capacity of 100000 Wh the daily rate would be 0.01*100000/24 = 41.667 Watts.
As for my car's phantom drain: I use that same curve from Stats. My particular rate is 0.29 mi/hr. Let's call it 0.3. I use about 300 wH to go a mile. 0.3(mi/hr)*(300 W•hr/mi) = 90 W.
I wish Stat's would give the cumulative rather than the density but they don't so we have to integrate the curve by eye but looking at the one you posted its plain that quite a few people have drains more than twice 0.3. Thus, IMO, what OP saw is, while perhaps at the high end of normal, nonetheless normal. It's certainly not indicative that someone left a spanner across a bus bar.
So 1% per day vampire drain is normal, per the user manual. So if the OP had more than 14% when he started his 14-day adventure, he would not be at zero. Is 255 km equivalent to 14% of the Model X battery? 255 km should be closer to 50% +/- depending on the specific model, right? So if 1% per day is normal, how is (50%/14 days = ) 3.57% per day also normal?.01 (fraction loss/da)*100000 = 1000 watt hr/da
1000 (watt hr/day)/24 (hr/day) = 41.667 watt.
Thus, IMO, what OP saw is, while perhaps at the high end of normal, nonetheless normal. It's certainly not indicative that someone left a spanner across a bus bar.
The car can be in one of several states
1)Sleeping
2)Idle/park
3)Neutral
4)Drive
5)Reverse
In 1) very little energy is drawn from the battery. Just enough to run the processes that allow the car to detect that an attempt is being made to connect to it. At the same time it is self discharging to some extent as discussed in previous posts.
In 2) several maintenance processes are being run. For example the car could be downloading software or reporting status to the Tesla App. Cabin preheating could be taking plave
in 3)The radio, lights, heater etc could be on
Thus if the car is in other than sleep it will be consuming more power. To keep vampire drain at a minimum do not make data requests from the car nor allow apps to do so. Don't approach it with the key, open its doors, sit in it, play the radio etc. Doing any of those things will drain the battery.
155 miles in 14 days! No way that is normal. Even if sentry and overheat are on, they turn off at 20% and the thing drops into deep sleep. I’ve noticed deep sleep is like 1-3 miles per day. Something happened to drop like that. Call Tesla and they can look and tell you what percentage your car was at and how much it lost per day.
