If your 2020 Audi A3 has issues with the MMI, there is a way to reset it. The only two options are: 1) The first option is to start the car and select 'Continue as Guest'. Although this is not an official Audi solution, this method works and will prevent any issues with the vehicle's instrumentation, eliminating annoying restarts.

Accessing as a user or guest makes no difference, so there will be no problems. 2) The second option is to visit an authorised Audi workshop or dealership and have a mechanic inspect the car, as the issue may be electrical.
