About Trouble Codes

NOTE:
- The following table lists all malfunctions that can be recognized by automatic vertical headlight aim control and printed out by the VAG 1551 scan tool. The malfunctions are listed in order according to their 5-digit numbers.
- DTC numbers appear only on the print-out.
- Before replacing a component shown as faulty, check the wiring and connections to the component as well as the Ground (GND) connections according to wiring diagram.
- After repairs and function test of the system, DTC memory must always be checked again using the VAG 1551 scan tool and erased.
- DTC memory records all static and sporadic malfunctions: A malfunction is recognized as being static if it occurs for at least 2 seconds. If the malfunction is no longer recognized after that it is stored as sporadic malfunction. "ISP" will appear at right on scan tool 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 during 50 driving cycles (ignition on at least 5 minutes, vehicle speed 30 km/h) are erased automatically.
