Diagnostic Trouble Code (DTC) table

NOTE:
  • The following table lists all the malfunctions that can be recognized by the instrument cluster and printed out by the VAG 1551. The DTCs are listed in order according to their 5-figure code numbers.
  • DTCs appear only on print-out.
  • Before replacing a component shown as malfunctioning, check wiring and connections to the component as well as Ground connections according to the wiring diagram.
  • After completing a repair and checking the function of the system, always check the Diagnostic Trouble Code (DTC) memory once again with the VAG 1551 scan tool and erase the memory.
  • The Diagnostic Trouble Code (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. (In the case of the ambient temperature display, a malfunction must persist for at least 60 seconds before it is classified as a static malfunction; in the case of the coolant temperature sender, static malfunctions are those which persist for at least 30 minutes with the engine running). 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.
  • 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) are erased automatically.
