About Trouble Codes

Diagnostic Trouble Code (DTC) Table


CAUTION!
After repairs the DTC memory of the engine control module must always be checked and the DTC memory content "Engine control module blocked" erased. Check and eliminate any further malfunctions stored.


NOTE:
- All static and sporadic malfunctions are stored in DTC memory: A malfunction is recognized as a static malfunction when it is present for a minimum of 2 seconds. If the malfunction is no longer present after this time, it is stored as a sporadic fault and "\SP" appears on the display.
- After switching on ignition, malfunctions stored are first recognized as sporadic and are changed to static if they are present after the check has been completed.
- If a sporadic malfunction is no longer present during the next 50 driving cycles (ignition on for a minimum of 2 seconds) it is erased.
- The following table lists all malfunctions, with the corresponding 5-digit code numbers, that can be recognized by the immobilizer control module and printed out by VAG 1551.
- DTCs appear only on a print-out.
- Before replacing a component shown as faulty, check wiring and connections to the component as well as Ground (GND) connections according to the wiring diagram.
- When repair has been completed, DTC memory must always be checked again with VAG 1551 and then erased.
