On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) II 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 out after
the engine starts and the idle has stabi lized .
This indicates that the MIL is working proper
l y.
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- tern.
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 dea ler.
If the light illuminates, the electronic speed
limiter may also be malfunct ioning. For more
information
q page 31, El ectronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
~page 213.
On-Board Diagnostics

On-Board Diagnostics monitors the compo
nents of your em ission control system . Each
monitored component in your engine system
has been assigned a code . In case o f a mal
function, the component will be identified
and the fault stored as a code in the control
module memory.
T he 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
