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
¢page 162.
On-Board Diagnostics
Fig. 23 Location of Data Lin k Co nn ector (DLC)
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
cial diagn ostic equipment (generi c scan tool
f or OBD).
In order to connect the spec ial diagnostic
equipment , push the plug into the Data Link
Connector (DLC). Th e DLC is located to the
right of the hood release
¢fig. 23.
Your authorized Audi dealer or a qualified
service s ta tion can interpret the code and per­
form the necessary repair.
~ARNING
Do not use the diagnostic connector for
personal use . Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!
Electronic speed limiter
Your vehicle may be factory equipped w ith
-
tires that are rated for a maximum speed of .,..

130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle also has an electronic speed limit­
er . The electronic speed limiter prevents your
veh icle from going faster than the tire speed
rating . For more informat ion
.:;, page 191 .
If the engine control unit receives faulty vehi­
cle roadspeed signa ls, the Malfunction Indica ­
tor L ight (MIL)
Ill will illuminate . If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.
S models
Your vehicle's top speed is elec tronically limit­
ed to 155 mph (250 km/h) .
If the engine control unit rece ives fau lty vehi ­
cle roadspeed signals, the Malfunction Indica­
tor Lamp (MIU
¢..ijj will illuminate. If th is oc­
curs, contact the nearest authorized Audi
dealer for assistance .
&, WARNING
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather conditions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed.
