How can I change the Mmi splash/startup screen? I have a 2019 s4 and the previous owner changed it to show a5 on start up. I want to change it back to s4. I have Ross tech vcds.

Looks like someone has changed the variant of the car. Look for threads where the folks of the B&O cars were changing the variants to the Q5 to get the subwoofer control back.
