VAG 1551 Display Overview, Display Group 014:

Notes on display groups 013 and 014, display fields 2, 3, and 4:
Knock regulation is active at an engine load greater than 40%, If the engine load value exceeds 40%, the current ignition timing retarding values are displayed. When the engine load value drops below 40%, the last ignition timing retarding value used is displayed continuously

When there is audible knocking without recognizable ignition timing retarding, the engine speed should be increased over 3500 RPM for 5 seconds to initiate the Knock Sensor (KS) malfunction recognition (diagnostic).

If the ignition timing retarding value of one cylinder clearly deviates from the other cylinders, the following malfunctions are possible:
^ Loose auxiliary components
^ Corrosion on the harness connector
^ Engine damage (oil consumption because of damaged rings/pistons).

If large ignition timing retarding values are displayed for an entire bank, the following malfunctions are possible:
^ Corrosion in harness connection, see display groups 015 and/or 016.
^ Improper knock sensor torque - torque to 20 Nm (15 ft lb)
^ Open circuit in wiring, see display group 015 and/or 016.
^ Knock sensor faulty, see display group 015 and/or 016.
^ Loose auxiliary components

If large ignition timing retarding values are displayed for all cylinders (banks 1 and 2), fuel octane is too low (less than 98 RON).
