My car basically rebooted instantly upon purchase whilst on cellular.This evening, I decided to take the plunge, and purchased the acceleration boost upgrade on my phone for my 2022 M3LR. For context, my vehicle sits in my apartment building’s parking garage (no Wi-Fi). When a software update is needed I typically let the car take care of itself while I’m at work as my office as my parking space is in range of my company’s Wi-Fi network. In the past I have connected the car to my iPhone’s data connection via tethering, but rarely.
Back to tonight - I purchase the upgrade and, obviously, am eager to experience the fruits of the damage to my credit card. I get in the car and connect it to my iPhone’s data connection. After a few seconds of the car’s data symbol indicating I’m on Wi-Fi, I start puttering through the settings to see if there’s an available software update. Nothing is showing as available. When selecting the drive settings, I notice that the car’s acceleration setting now has “sport” available (an indicator that the acceleration boost package has been enabled).
Strange, right? As the car hasn’t had a software update since I purchased the upgrade 4-5 minutes ago on my phone.
I check the “software” tab and the vehicle indicates “acceleration boost” package being enabled.
I take the car out for a spin and - woah - yes the car is unquestionably accelerating faster!!
Perhaps a recent software update placed the upgrade in a local folder, to make the purchase experience quicker, so that the car only had to receive an “unlock signal” from Tesla’s servers once the purchase has successfully executed? The app on my phone did show a disclaimer that the car may take several hours for the software to upgrade itself. But - no update took place.
Seems it doesn't need an actual 'update', it just changes something then full-resets the car. Once it's back up you're good to go
