Coding and Programming Requirements

Coding and component-protection removal are normally required when installing this MMI main unit into a different vehicle.

The replacement unit may require vehicle-specific coding, adaptation and software configuration using Audi-compatible diagnostic equipment with authorised online access.

Navigation activation, map compatibility and other enabled features may also need to be checked according to the unit's region, software and licensing status.

A used unit from another vehicle should not be considered plug-and-play. If the original unit is repaired and reinstalled into the same vehicle, additional component-protection removal is not normally required.

Installation Information

Professional installation by an Audi technician or experienced automotive infotainment specialist is strongly recommended.

The vehicle should be diagnostically scanned before replacement to confirm that the MMI main unit is responsible for the fault. The display, wiring, antennas, media connections, MOST fibre-optic network and power supply should also be inspected.

After installation and commissioning, the navigation, audio, multimedia, telephone, display and vehicle-menu functions should be tested for correct operation.
