I have a late 2016 90D AWD with FSD and HW3 computer upgrade. I have not received an upgrade since 2020.48. I this because I am still on MCU1? My MCU has occasionally blanked out but not lately. My understanding is that it is just a matter of time until it does. the band aid software patch seems to be working for now but I remember reading that the MCU upgrade would be free with failure. Any insight would be appreciated.
