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 in the instrument cluster by the warning lamp for Electronic Power
Control ("EPC warning lamp"); Notes for E-gas system Page 24

.
Malfunctions that worsen emissions are also indicated by an exhaust warning lamp (MIL) 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. Meaning of exhaust MIL Page 01
-3 .
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).
