Notes on display fields 2, 3 and 4: Display groups 013 and 014
- Knock control is active starting at an engine load greater than 40%. If the engine load exceeds 40%, the current ignition timing point retarding value is displayed; if the engine load drops below 40%, the last values used are displayed constantly.
- If there is audible knocking without recognizable retarding of the ignition timing point, the engine speed should be increased over 3500 RPM for 5 seconds to initiate the knock sensor malfunction recognition (On Board Diagnostic).

- If an ignition timing point retarding value of one cylinder deviates from the others, the following malfunctions are possible:

- Loose subassemblies
- Corrosion on the harness connector
- Engine damage (e.g. oil combustion with faulty piston)

If there are high ignition timing point retarding values on all cylinders of bank 1 or bank 2, the following malfunctions are possible:

- Corrosion on the harness connector display groups 075 and 016
- Knock sensor tightening torque, 20 Nm (14 ft lb), not OK
- Open circuit display groups 015 and 016
- Knock sensor faulty
- Loose subassemblies

If there are high ignition timing point retarding values on all six cylinders (banks 1 and 2), the car has been filled with fuel having low octane (less than 98 RON).
