Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
