Turbocharge Bypass Valve Open. P1287 on Volkswagen vehicles indicates that the engine control module has detected an open circuit in the turbocharger bypass valve circuit, which is also known as the diverter valve or recirculation valve. The computer monitors the electrical path to the valve and sets this code when the expected voltage or current is missing, meaning the valve cannot be commanded to open and vent boost pressure.
