Code P1287 Volkswagen Description
The P1287 code for Volkswagen indicates that the turbocharger bypass valve is open when it should be closed. The turbocharger bypass valve, also known as the wastegate, is responsible for controlling the boost pressure produced by the turbocharger. When the valve is open, it allows excess exhaust gases to bypass the turbocharger, resulting in reduced boost pressure and potentially decreased engine performance.
