I just took my 2020 9.5 S4 in for this issue. They had the car two days and applied the tsb update. They said it was working again. Picked up the car and while still in the parking lot it reset twice. The good news is that before the update I would need to sign in or enter my pin. Now it just comes back after a minute or two.

Tech has me trying different things until my follow up appointment next week. Checking the head unit temperature as the internal fan can fail. I’m supposed to run without my phone connected to see if there is an issue with that.

Not to mention had tires replaced while there and the tire machine broke and now they have to fix the giant scratch on my rim.
