Diagnostic Trouble Code (DTC) table

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2005 Audi allroad, 2004 Audi allroad, 2004 Audi A6, 2003 Audi allroad, and 2003 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. Notes on Engine Power Control (EPC) (drive by wire). See ELECTRONIC ENGINE POWER CONTROL (EPC), CHECKING .
Malfunctions relating to the electronic throttle are also indicated by the EPC (Electronic Power Control) warning light in the instrument cluster.
Malfunctions which adversely affect exhaust emissions are indicated by an Exhaust Malfunction Indicator Light (MIL), the MIL is located in the instrument cluster. As soon as certain malfunctions are recognized, the MIL is switched on immediately. There are also malfunctions where the MIL is switched on only after the engine is started again.
Sporadically occurring malfunctions (temporary malfunctions) will be indicated on the VAG1551 display as "SP."
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.
Components that are indicated as being faulty by the VAG1551 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).
If the connector for the engine control module is disconnected or if the battery is disconnected, all the learned values (adaptation 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 idling may be rough at first. In this case let the engine run at idle for a few minutes until the adaptation is fully carried out.
After erasing the DTC memory (see DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING AND ERASING ) and generate a new readiness code (see READINESS CODE, GENERATING ).

Note for malfunction P1624:

MIL stands for Malfunction Indicator Light. Once the Engine Control Module (ECM) recognizes a malfunction that adversely affects the exhaust emissions it switches the MIL on .
The MIL is switched on only by the Engine Control Module (ECM), since the ECM has the only connection to the MIL ..
Malfunctions that affect the exhaust emissions can also be recognized by the Transmission Control Module (TCM), These malfunction are also indicated by the MIL .
Once the TCM recognizes a malfunction that adversely affects the exhaust emissions it sends a message to the ECM, the ECM then switches the MIL on. Simultaneously, the malfunction P1624 stored in the ECM noting that the MIL is switched on due to a transmission problem and not because of a engine problem .
