Diagnostic Trouble Code (DTC) table for instrument cluster

Notes:

The following table lists all possible Diagnostic Trouble Codes (DTCs) which the instrument cluster can recognize and
which the VAG1551 scan tool can print.
DTC numbers only appear on the printout.
Before replacing any component shown as malfunctioning, check all related wiring and connections of these components
and the Ground (GND) connections Electrical Wiring Diagrams Troubleshooting & Component Locations After the repair has been carried out and the functional system check, re-check and erase the DTC memory using the
VAG1551 scan tool.
The DTC memory records all static and sporadic (intermittent) malfunctions. A malfunction is considered static if it exists
for at least 2 seconds (exceptions: 60 seconds for outside temperature display and 30 minutes, for engine coolant sensor).
If the malfunction is not present after this time, it will be stored as a sporadic DTC and "/SP" will appear on the right side of
the scan tool display.
After switching the ignition on, all existing DTCs are set to sporadic. If they are still present after the system check, they
will be stored as static DTCs.
If a sporadic malfunction does not reoccur within 50 driving cycles (ignition on for at least 5 minutes and vehicle speed
greater than 30 km/h or 18 mph), it will be erased.
