Turn on the ignition and let the MMI fully initialize. Access the "Red Engineering Menu" (REM). On most Audi models, this is done by holding two specific buttons simultaneously (e.g., NAV/MAP + MEDIA or Back + upper left function button ) for 5–10 seconds. Start the Update: Insert the SD card into Slot 1. In the Engineering Menu, select Update . Select the source (SD1).
