About Trouble Codes

Diagnostic Trouble Code (DTC) Table

NOTE:
- The DTCs are listed according to the 5 digit malfunction code on the left.
- Some of the listed DTC texts are displayed only on the VAS 5051. In this case only the malfunction code is printed out using the V.A.G 1551.
- Possible malfunctions depend on the vehicle equipment.
- Explanation of the malfunctions (e.g. "open circuit/short to ground").
- Before replacing components indicated as being faulty, check the wiring and connectors to these components as well as the ground (GND) connections using Electrical Wiring Diagram. This is particularly relevant if faults are output as "occurring sporadically" (SP).
- The malfunctions displayed can be localized using the test table.
- The DTC -"01330; Convenience central control unit; no communication" - can appear "sporadically". This has no influence on the function of the Comfort System (vehicles with power windows) and is therefore of no consequence.
- This malfunction "no communication" can also appear with the door control units. This has no influence on the function of the Comfort System (vehicles with power windows) and is therefore of no consequence. Erase DTC memory.

Scan tool print out: The number 049 (example) in bold type is of no consequence.
