This newer style turbo outlet dampener is required for all Early 2009 Jetta TDI (manufactured before July 21, 2009) when replacing the turbocharger. New turbochargers come with a revised outlet that will not work with the factory outlet damper. The turbocharger outlet damper minimizes air and whistling noises from the turbocharger.
