Q: What does code P1210 mean?

Intake Valves For Cylinder Shut-Off Short To B+. P1210 on Volkswagen vehicles indicates that the engine control module has detected a short to battery voltage on the control circuit for the intake valves of the cylinder shut-off system. This circuit normally operates the solenoids that disable the intake valves on specific cylinders to improve fuel economy, and a short to B+ means the control wire is receiving constant power when it should be pulsed by the module.
