Malfunction Indicator Lamp (MIL )
The Malfunction Indicator Lamp (MIL) ¢"4 in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system. T
he warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the id le has stabilized .
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
is started, or illum inates while you are dr iv­
ing, a malfunction may exist in the engine sys­
tem . If the light illuminates, the catalytic con­
verter could be damaged .
Cont inue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your authorized Audi dea ler .
An improperly closed fuel filler cap may also
cause the
MIL light to illuminate

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

If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler
