AFFECTED VEHICLES
CONDITION
In vehicles with a Bang & Olufsen sound system (PR No. 9VK), the customer may complain the sound is distorted or completely inoperative. Often this complaint arises after accessories or aftermarket equipment has been installed (e.g. window tinting). TECHNICAL BACKGROUND
It is possible the amplifier has been damaged by water, for example from window tinting or ingress into the trunk compartment.

WARRANTY INFORMATION
Tip: Amplifier damage as a result of window tinting is due to outside influence and is not covered by any Audi warranty.
If a leak is found in the trunk compartment, claim the complete repair on the service number of the leaking (damage-causing) part ID.

The following Technical Service Bulletin(s) will be necessary to complete this procedure:
