I gave up on waiting for Tesla a couple weeks ago and bought a used module off ebay for about $150 and installed it myself. Much cheaper than what Tesla charges, which is not bad for 30 minutes work. It's really quite easy to do. The trickiest thing is getting the trim off and back on. Swapping the module itself takes about one minute and really can't be done incorrectly. You don't even need to disconnect any batteries or power down the car.Wow, $100 cheaper is a nice bonus for waiting so long. I’m still unable to add to cart as others indicate, but progress!
After swapping the module, you must do a software reinstallation from the service mode and you're good to go. I verified regular L2 charging, then drove down to a nearby Buc-ees and verified that both supercharging and CCS charging worked.
I already had the CCS adapter for my Model Y, so all I needed was the electronics module. I've used it a couple times since then on different networks just to be sure all is good and it's worked every time.
