Coding and Programming Requirements

Component-protection removal, coding or vehicle-specific configuration should generally be expected when installing this amplifier into a different vehicle.

A replacement amplifier may provide restricted or unavailable audio operation until the module has been correctly authorised and matched to the receiving vehicle.

The unit may require component-protection removal, coding, parameterisation and software configuration to match the vehicle's infotainment system, speaker arrangement and factory Bose equipment.

A used amplifier from another vehicle should not be considered guaranteed plug-and-play. If the original amplifier is professionally 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 recommended.

The vehicle should be diagnostically scanned before replacement to confirm that the amplifier is responsible for the fault. The speakers, wiring, power supply, earth connections and infotainment system should also be inspected.

The amplifier installation area should be checked for water entry, moisture and corrosion before the replacement unit is fitted.

After installation and configuration, the complete audio system should be tested to confirm correct speaker output, volume, balance, fade and communication with the factory infotainment system.
