Service Technical Information 67/23 ENU WNP5 8 WNP5 - Replacing Drain Hose on Heating/Fresh-Air Unit (Workshop Campaign) Model Line: Cayenne (92A) Model Year: As of 2017 up to 2018 Concerns: Drain hose on heating/fresh-air unit Cause: A drain hose not manufactured according to specifications may have been installed on the heater/fresh-air unit on affected vehicles.

As a result, moisture can enter the vehicle interior via the footwell ventilation duct. Action: Replace the drain hose on the heating/fresh-air unit. Affected Vehicles: Only vehicles assigned to the campaign (see also PCSS Vehicle Information).
