Here is what I have found so far: Tesla wanted app CLOSED and bluetooth OFF overnight. In the morning car was off and stayed off. Turned on app and bluetooth was wakes for about 20 minutes, off 30 seconds then back on. Drive and tried again. App off Bluetooth ON. Awake 30 minutes off 6 minutes then awake. App off AND Bluetooth OFF - Awake 15 minutes, off - over 1 hour and I stopped waiting for a wakeup. SO bluetooth is waking the car through the IOS app 4.12.0 (or 4.12.1). Explains why Tesla wanted bluetooth off overnight. No need to go to airplane mode or shut off phone. Just closed app (so banner reminding its not in background) and bluetooth off stops the cycling. I've forwarded to Tesla.
