Diagnostic Trouble Code (DTC) table, interior monitoring
Notes:
The following table lists all the DTCs that can be recognized by the control module for interior monitoring and printed out
by the VAG1551 Scan Tool (ST). The DTCs are listed in order according to their 5-digit numbers.
DTC 5-digit numbers appear only on the print-out from the scan tool.
Before replacing a component shown as malfunctioning, check wiring and connections to the component as well as the
Ground (GND) connections according to the relevant wiring diagram.
When a repair has been completed, the system should be armed and then disarmed. Then check and erase DTC memory
using the VAG1551 Scan Tool (ST).
DTC memory records all static and sporadic malfunctions. When a malfunction occurs, it is first identified as a static
malfunction. If it does not occur again it is registered as a sporadic malfunction, and the letters "/SP" appear at the right of
the display.
After system is armed, all existing malfunctions are automatically re-classified as sporadic malfunctions and will only be
registered as static malfunctions if they still occur after testing.
Sporadic malfunctions which no longer occur after 50 driving cycles are erased automatically.
The three digit malfunction type number appearing next to the DTC is a data code which may be disregarded.
