Service Technical Information 22/22 ENU WNA6 5 WNA6 - Reworking Fastening Bolts on the Underbody (Workshop Campaign) Model Line: Cayenne (9YA/9YB) Model Year: 2022 Concerns: Fastening bolts on underbody Information: Due to an error during the production process, fastening bolts that do not meet the required specifications were installed on the affected vehicles. If, therefore, the tolerances in the body structure are unfavorable, there is a possibility that contact could occur between the fuel tank and fastening bolt while driving and this could result in a fuel tank leak over the service life of the vehicle. Action required: Remove fastening bolts on underbody. The fuel tank must also be checked for damage and replaced if necessary. Affected Vehicles: Only vehicles assigned to the campaign (see also PCSS Vehicle Information).
