Diagnostic Trouble Code (DTC) table for instrument cluster

Notes:

The following table lists all malfunctions that can be recognized by the instrument cluster and printed out by the VAG1551
scan tool. The malfunctions are listed in order according to their 5-digit numbers.
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 and function test of the system, DTC memory must always be checked again using the VAG1551 scan tool
and erased.
DTC memory stores all static and sporadic malfunctions: If a malfunction occurs and persists for at least 2 seconds, it is
identified as a static malfunction (outside temperature malfunction at least 60 seconds, coolant temperature sensor only
after at least 30 minutes with engine running). 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 during 50 driving cycles (ignition on at least 5 minutes, vehicle speed 30
km/h) are erased automatically.
