On-Board
Diagnostic
system
(OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Ind icator Lamp (MIL)
ISi
in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator
light ill umina t es 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 work ing proper-
ly.
If the light does not go out
after t he engine
is started, or illuminates while you are driv-
ing, a malf unction may exist in the engine sys-
tem.
If
the light illumi nates, the catalytic con-
verter could be damaged .
Contin ue driving
with reduced power
(avoid-
ing susta ined high speeds and/or rapid accel-
erations) and have the cond ition corrected .
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed
li miter may also be malfunct ion ing. For more
information ¢ page 2 8, Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
<=> page 213.
On-Board Diagnostics

On-Board Diagnost ics monitors the compo -
nents of your em ission cont rol system . Each
monitored component in your engine system
has been assigned a code. In case of a mal -
functio n, the component will be identified
and t he 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 f uel vapor recovery sys-
tem. If the light illum inates afte r a refuelling,
stop the vehicle and make sure t he fuel fille r
cap is properly closed ¢ page 213.
In order to make an accurate diagnosis , the
stored data can only be disp layed using spe-
cial diagnostic equipment (generic scan tool
