What does code P1550 mean?

Q: What does code P1550 mean?

Charge Pressure Deviation. P1550 on Volkswagen vehicles indicates that the engine control module (ECM) has detected a deviation between the actual charge pressure measured by the manifold absolute pressure (MAP) sensor and the target charge pressure commanded by the turbocharger control system. This means the turbo is not producing the expected boost, either because of a mechanical fault, a control issue, or a sensor error.
