Diagnostic Trouble Code (DTC) table

2001 Audi A6 Avant QuattroSECTION Diagnostic Trouble Code (DTC) table

NOTE:

When malfunctions occur in monitored sensors or components, Diagnostic Trouble Codes (DTCs) are stored in DTC memory with a description of the malfunction type.
"EPC"-relevant malfunctions are also indicated in the instrument cluster by the warning lamp for Electronic Power Control ("EPC warning lamp"). See ELECTRONIC ENGINE POWER CONTROL (EPC), CHECKING .
Malfunctions that worsen emissions are also indicated by an exhaust warning lamp (MIL for output DTM) that is also located in the instrument cluster. There are malfunctions that cause the exhaust warning lamp to light up immediately after recognition. Malfunctions can also occur that do not cause the exhaust MIL to light up immediately, but only if malfunction is recognized again after repeated engine starts.
The DTC table is organized by the 5 digit code at left.
If a stored DTC does not recur within the next 40 warm -up cycles, the DTC will be erased automatically.
Malfunctions that occur only sporadically (temporary malfunctions) are are identified by the letters "SP" (sporadic malfunction) on the VAG1551 scan tool display. The word sporadic means "appearing or occurring at irregular intervals, occasional".
Do not immediately replace components that the VAG1551/VAS5051 suggests are faulty, instead: Check wire connections and harness connectors to these components according to wiring diagram. Also check Ground (GND) connections according to wiring diagram. This is particularly valid when malfunctions are displayed as "sporadically occurring" (SP).
If the connector is disconnected from the ECM or the battery is disconnected, all adaptation values in the control module are erased. DTC memory content will remain intact however. If the engine is started after this, a rough, uneven idle can result. In this case, engine must be allowed to run at idle for a few minutes until adaptation procedure has been completed.
After erasing DTC memory (CHECK DTC MEMORY (FUNCTION 02) AND ERASE DTC MEMORY (FUNCTION 05) ), readiness code must be re -generated. See READINESS CODE, GENERATING .

The DTC "Fuel Level Too Low" is stored when there is/was too little fuel in fuel tank. The DTC is stored as a static malfunction and is not switched to sporadic even if fuel tank has been filled with fuel (e.g. by the customer) in the meantime. In this way, it can be determined that subsequent malfunctions were caused by lack of fuel, e.g. combustion misfires or oxygen control related malfunctions.
