On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
T he Malfunction Indicator Lamp (MIL) ¢4 in
the instrument cluster
Q page 14, fig. 8 is
part o f the On-Board Diagnostic (OBD II) sys
tem.
T he warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the idle has stabilized .
T his indicates that the MIL is working proper
ly .
If the light does not go out after the engine
is started, or illuminates while you are driv
ing, a malfunction may exist in the engine sys
tem. If the light illuminates, the catalytic con
verter could be damaged.
Continue driving
with reduced power (avoid
ing sustained high speeds and/or rapid accel
erat ions) and have the condition corrected .
Contact your author ized A udi dealer.
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
information
Q page 2 7, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
Qpage231 .
On-Board Diagnostics
Fig. 21 Location of Data Li nk Conn ecto r (DLC)
On-Board Diagnostics monitors the compo
nents of your emission control system . Each
monitored component in your engine system
has been ass igned a code . In case of a mal
function, the component will be identified
and the fault stored as a code in the control
module memo ry.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys
tem .
If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed
Q page 231.
In order to make an accurate diagnosis , the
stored data can only be displayed using spe
cial diagnostic equipment (generic scan tool
f or OBD).
In order to connect the spec ia l diagnostic
equipment , push the plug into the Data Link
Connector (DLC). Th e DLC is located to the
right of the hood release
Qfig. 21.
Your authorized Audi dea ler or qualified work
shop can interpret the code and perform the
necessary repair.

Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!
