Data usage on the “About Your Tesla” screen

While waiting in my Model S with a hotspot, hoping that it would pick up the 2018.10.4 update, I noticed a pattern. Whenever the “About Your Tesla” screen is open, I see 23mb data consumption on my hotspot. It stops after that. If I re-open that screen, another 23mb goes through, and stops again. This has happened 10 times in a row now (yes, I want that update badly). Do you think this is a trigger to download a chunk of the new firmware?
I received the update prompt! In the meantime, I noticed the following behavior:
  • After the ~10th cycle, I left the “About Your Tesla” screen open. The car kept generating network traffic at a slow rate, creeping up to a total of ~350mb
  • After a while, the car locket itself. Data consumption continued at the same rate
  • Some more time had passed, and all the MCU fans stopped, and immediately the download speed increased drastically!
  • Network activity stopped at a total of 651mb, then the MCU fan came on
  • I received the update notification on my phone
It could be that the “About Your Screen” is a red herring, and the MCU interrupts downloads as soon as the user is interacting with the car (I may have adjusted the climate control while in the car). BTW, I didn’t have my key with me, the car was opened with the phone app.
I got 2018.6.1 - tried your method, many times, (went to the car and clicked about, left) - got to 2.1GB and then gave up...
It was not a hotspot, rather my car's own WiFi access point , (and the access points wifi stats) , really fast fiber connection to the net.

I wish we could see anyone confirm this method.

So the frigging release notes aren't even local?! Jeez... I can see it checking for updates, but, good grief, this may be taking connected devices just a bit too far... :D

I think we thought there was a flag when the maps were installed and you got updated notes, not that every time you touched that link, it fetched a new copy. No cache? We need one of the rooted guys to chime in here...
