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 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¢
page 162 .
In order to make a n accurate diagnosis, the
stored data can only be displayed using spe­
