Diagnostic Trouble Code (DTC) table, central locking
Notes:
The following table lists all the DTCs that can be recognized by the control module for central locking 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, check and then erase DTC memory using the VAG1551 Scan Tool (ST). After that,
the vehicle should be locked again (with key or remote control) and DTC memory checked again.
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.
When the ignition is switched on, 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.
