Diagnostic Trouble Code (DTC) table

WARNING: This page is about a different car, the 2004 Audi A6, 2003 Audi A6, 2002 Audi A6, 2001 Audi A6, and 2000 Audi A6. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

If malfunctions occur in the sensors and components being monitored, they will be stored in the DTC memory together with an indication of the type of malfunction.
Malfunctions relating to the electronic throttle are also indicated by the EPC (Electronic Power Control) malfunction indicator light in the instrument cluster.
Malfunctions, which decrease the emissions, are indicated by the Malfunction Indicator Light (MIL) which is also located in the instrument cluster. For some malfunctions the MIL is switched on as soon as the malfunction is recognized. Some malfunctions can appear and the MIL will only be switched on after the engine is started again.
If the connector for the engine control module is disconnected or if the battery is disconnected, all the learned values stored in the control module will be erased, although the contents of the DTC memory will remain intact. The next time the engine is started the idle may be rough at first. In addition, the following adaptation procedures must be performed. See THROTTLE VALVE CONTROL MODULE -J338-, CHECKING .
The DTC table is arranged according to the 5-digit DTC in the left-hand column.
If a malfunction is stored in the DTC memory and then does not occur again during the next 40 engine warm-up phases, the DTC will be automatically erased.
Sporadically occurring malfunctions (temporary malfunctions) will be indicated on the VAG 1551 display as "SP".
Components that are indicated as being faulty by the VAG 1551 should not be replaced immediately. Always start by checking the wiring, connectors and Ground (GND) connections for the component using the current wiring diagram. This is particularly important in the case of sporadic malfunctions (indicated by the letters "SP" on the scan tool display).
After erasing the DTC memory. See DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING AND ERASING . Generate readiness code. See READINESS CODE, GENERATING .
