Official summary
In affected vehicles, the turbocharger housing included an unintended and unused hose port. To avoid possible oil seepage or a small air leak over time, Volkswagen will proactively replace the turbocharger. Based on engineering judgement, this incorrect part is not anticipated to impact performance, fuel consumption, or emissions.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
