Diagnostic Trouble Code (DTC) table

The following table lists all malfunctions that can be recognized by the navigation system 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 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. "ISP" 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 40 driving cycles (ignition on at least 5 minutes, vehicle speed 30 km/h) are erased automatically.

NOTE: Some OBD program text/data generated by control modules may not be recognized by VAG 1551/1552 scan tools with the latest program card. For example: scan tool display shows "text 799", "01529 /references" or similar. In these cases, use VAS 5051 tester instead.
