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.
- "E-Gas"-relevant malfunctions are also indicated by the fault light for power accelerator activation (EPC warning lamp).
- 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.
- Malfunctions that occur only sporadically 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".
- 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.
- Do not immediately replace components that the VAG1551 suggests are faulty, instead: Check wire connections and harness connectors to these components according to wiring diagram. Also check Ground (GND) connections according to the 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 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 DTC memory readiness code must be re-generated Readiness Code, Generating
