Concerns: Rear-axle disc brake pads Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a possibility that disc brake pads from a batch that does not conform to the high quality standards of Porsche may have been installed on the affected vehicles. As a result, there may be increased noise from the brake system when braking in certain environmental conditions.
