On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) Ill in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes o ut after
the engine starts and the idle has stabilized.
This indicates that the MIL is working proper
ly.
If the light does not go out after the engine
is started, or illuminates whi le you are driv
ing, a ma lfunction 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
erations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
information ¢
page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostics
Fig. 23 Location of Data Lin k Co nn ector (DLC)
On-Board D iagnostics 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
funct ion, the component will be identified
and the fault stored as a code in the control
module memory.
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 refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed¢

In order to make a n accurate diagnosis, the
stored data can only be displayed using spe
