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.
PRODUCTION SOLUTION
Not applicable.
SERVICE
1. Check the amplifier for evidence of water damage (stains, corrosion, etc.).
2. If confirmed, the source of the water must be found and corrected to prevent a repeat repair. If the windows were not tinted, check for potential
leaks around the trunk seal. Spray the vehicle and thoroughly check the amplifier area for water drops.
3. Using the deflector listed in the Required Parts and Tools section below as a template, drill three 6.5 mm holes in the left side trunk compartment
cover.

4. Install the deflector using the expanding rivets.
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.
