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).
It is possible the amplifier has been damaged by water, for example from window tinting or ingress into the trunk compartment.
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.
