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

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

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
