battery AUDI A4 1998 B5 / 1.G AWM Engine Diagnostic Trouble Code Memory Checking Workshop Manual

Diagnostic Trouble Code (DTC) table

Notes:

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
-120
.
Malfunctions that worsen emissions are indicated by an exhaust warning lamp (MIL) in the instrument cluster. Notes for
Malfunction Indicator Lamp (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 sporadically (temporarily occurring malfunctions) are identified with "sporadic" on display. The
word sporadic means "appearing or occurring at irregular intervals, occasional".
Do not immediately replace components that the 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 "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 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.
