Radio System, On-Board Diagnostic (OBD)

Diagnostic Trouble Code (DTC) Table For Radio System

NOTE:
- The table lists all the DTCs that can be recognized by the radio system and printed out by the VAG 1551. The DTCs are listed in order according to their 5-digit numbers.
- DTCs appear only on print-out.
- Before replacing a component shown as malfunctioning, check wiring and connections to the component and Ground (GND) connections according to wiring diagram.
- After carrying out repair work and testing the system, the Diagnostic Trouble Code (DTC) memory must always be checked again and erased using VAG 1551 scan tool.
- The 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 the malfunction does not occur again it is registered as a sporadic malfunction and the letters "/SP" 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 register as static malfunctions if they still occur after testing.
- If a sporadic malfunction no longer occurs after the radio is switched on and off 40 times (ignition on for at least 5 minutes, vehicle speed symbol-not-found 30 km/h), it will be erased.
