Q: What does code P1330 mean?

Cylinder 6 Knock Control Limit Attained. P1330 on a Volkswagen indicates that the engine control module (ECM) has detected excessive knock activity on cylinder 6 and has reached the limit of its ability to retard ignition timing to suppress it. The ECM monitors the knock sensor signal for each cylinder and, when the voltage pattern for cylinder 6 indicates persistent detonation beyond a calibrated threshold, it stores this code and may illuminate the check engine light.
