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).

Format the SD card to FAT32 (or exFAT if the files are larger than 4GB). Copy the firmware files (usually including a metainfo2.txt file and several folders) directly to the root of the SD card. Do not put them in a subfolder. mh2peraug35p2873 install

It is critical to connect your vehicle to a battery charger (stable power supply) during the update. If the car loses power during the flash, the MMI unit can be permanently damaged ("bricked"). Turn on the ignition and let the MMI fully initialize

After the update, you may see a "Return to Main Menu" option. You might notice a "Software Version Management" (SVM) fault code if you scan the car with a tool like VCP (Vag Can Professional) or OBDeleven . This is normal and can be cleared using an SVM calculator or specialized diagnostic software. Critical Warning for Bose/Bang & Olufsen Systems Start the Update: Insert the SD card into Slot 1
