Diagnostic Trouble Code (DTC) table
- The following table lists all malfunctions that can be recognized by the anti-theft immobilizer and printed out by the VAG 1551 scan tool. The malfunctions are listed in order according to their 5-digit numbers.
- DTCs of the instrument cluster can also be shown since the anti-theft immobilizer is integrated in the instrument cluster.
- DTC numbers appear only on the print-out.
- Before replacing a component shown as faulty, check the wiring and connections to the component as well as the Ground (GND) connections according to wiring diagram.
- After repairs, DTC memory must always be checked again using the VAG 1551 scan tool and erased.
- DTC memory records all static and sporadic malfunctions: If a malfunction occurs and persists for at least 2 seconds, it is identified as a static malfunction. If a malfunction does not occur again, it is registered as sporadic. "/SP" will appear at right on scan tool display.
- When the ignition is switched on, all existing malfunctions are automatically re-classified as sporadic malfunctions and will only register as static malfunctions if they still occur after testing.
- Sporadic malfunctions which no longer occur after 50 driving cycles (ignition on at least 5 minutes, vehicle speed above 30 km/h) are erased automatically.
