Q: What does code P1586 mean?

Engine Mount Solenoid Valves Short To B+. P1586 on Volkswagen vehicles indicates that the engine control module has detected a short to battery voltage on the circuit for the engine mount solenoid valves, which are used to vary the stiffness of the hydraulic engine mounts for vibration control. The computer monitors the control circuit and sets this code when the voltage on the solenoid control wire is abnormally high, suggesting a short to a power source rather than a normal ground-switched signal.
