Diagnostic Trouble Code (DTC) Table For Radio System

NOTE:
- The following table lists all the malfunctions (stored as Diagnostic Trouble Codes, or DTCs) that can be recognized by the radio system and printed out by the VAG1551 Scan Tool (ST). The DTCs are listed in order according to their 5-digit numbers.
- The DTCs only appear on the print-out from the scan tool.
- Before replacing a component shown as faulty, check the wiring and connections to the component as well as Ground (GND) connections according to the wiring diagram.
- When a repair has been carded out, the DTC memory must always be checked again and then erased using the VAG1551 scan tool.
- Static and sporadic malfunctions are stored in DTC memory. If a malfunction occurs and persists for at least 2 seconds, it is identified as a static malfunction. If the malfunction does not occur again it is registered as a sporadic malfunction and "ISP" will 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 (ignition on for at least 5 minutes, road speed of more than 30 km/h or 19 mph) are erased automatically.
