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.
- Malfunctions related to EPC are also indicated by the warning lamp for the electronic throttle control ("EPC warning lamp") which is situated in the instrument cluster. Notes on EPC system. Electronic Power Control (EPC) System, Significance
- Malfunctions that degrade emissions are also indicated by an Malfunction Indicator Lamp (MIL) that is also located in the instrument cluster. There are malfunctions that cause the MIL to light up immediately after recognition. Malfunctions can also occur that do not cause the MIL to light up immediately, but only if those malfunctions are recognized again after repeated engine starts. Notes for exhaust warning lamp (MIL). Malfunction Indicator Lamp (MIL) -K83-, Significance
- The malfunction table is sorted according to the 5-digit DTC on the left.
- Sporadic malfunctions (malfunction occurring from time to time) are indicated as "sporadic" on the display. The word "sporadic" signifies individually occurring, random malfunctions.
- Do not immediately replace components indicated as faulty by the VAS 5051 but: first check the wiring and connectors of these components against the wiring diagram. Also check Ground (GND) connections according to wiring diagram. This is particularly relevant for DTCs recorded as "sporadic.
- 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 however remain intact. 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 the Diagnostic Trouble Code (DTC) memory, the readiness code must be regenerated .
