So for anyone wondering what the symptoms are:

First I noticed an increase in wh/mi usage when it got cold, but no warnings on the car. I didn't pay too much attention to it.

Within a day, I got this message

And my power was reduced to 100kw, and my regen was reduced to 0 (i.e. no regen at all)

The part is: MDL S, DM, THERM SYS, ELEC BATT HEATER(1038901-00-G)
The cost is $650+ with tax

@Max* , did they diagnose the issue remotely or did you have to take it in to a service center?
Take it in. Made an appointment in the app for a week out (or more?), they contacted me pretty quickly and made a next day (I think?) appointment.

They said something about not being able to pull the logs remotely, not sure why. Took them a day to diagnose it (though my car was sitting in the parking lot, so they were probably just backed up), and maybe another half day to fix it.

Hello,

I got this message once by the SuperCharger and I replug it in and I didn’t appear anymore. But after this the ventilation go full running and it bubbels in thé cooling reservoir!! Now sometimes I hear it bubbling but Tesla Service Center says nothing too worried

I did a reboot, mine was persistent. And it was there a few days in a row before getting fixed.

I am handy, but I already had it done since I wasn't sure what it was until I got to the Service Center.

I'm surprised about the huge price fluctuations for the same defect.
 
My heater is not working. I took Frunk out today, pump 1 is running 24/7. But water stayed at outside temp, 50. Should be 65 to 75 optimum. My car will not super charge cause temp is too low. It starts at 37kw. I have to get pump off Ebay and change it.
