The warning/indicator light appears in the event of a
significant loss of air pressure .
The ..Jwarning/indicator light illuminates for a few seconds after the
ignition is turned on as function check and then goes out .
If the symbol appears, pressure is too low in at least one tire.
When the system detects a ma lfunction, the warning/ind icator light
will flash for approximately one minute and then remain continu­ ously i lluminated. This sequence will continue upon subsequent
vehicle starts up as long as the malfunction exists . Contact your
authorized Audi dea ler and have the ma lfunction corrected .

Instruments and warning /indicator lights
Electronic Stabilization Program (ESP}
r /
The warning/indicator light monitors the electronic
stabili zation program.
The warning/ind icator light ,., has the following functions:
• it flashes wh ile you are drivi ng, when the ESP or the ASR (Ant i-Slip
Regulation) is working .
• it ill um ina tes when yo u sw itc h on the ignition for app rox imately 2
seconds as a funct ion check .
• it illum inates w hen there is a malfunction in the ESP .
• it illum inates after the battery has been disconnected.
• it illum inates continuously when the ESP is switched off.
• it illumi nates if the re is a malfunct ion in t he ABS, s ince the ESP is
part of the ABS system.
If the ESP warning/ind icator light ill umina tes and stays on after you
have started the engine, this may mean that the co ntro l system has
tempo rari ly switched off the ESP. If this is case , you can reactivate
the ES P by sw itch ing t he ig nit ion off and the n on agai n. The
warning/indicator light should go out to show that the system is fu lly
fu nctional again .
The ESP warn ing/ind icator light will illuminate when the ignition is
switched on if th e ve hicle bat tery has been disconnected and the n
reconnected aga in . The light should go ou t after dr iv ing a short
dis tance if the steer ing whee l is turned s lig htly.

Malfunction Indicator Lamp (MIL}
(USA models}/ (Canada models}
The Malfunct io n Indicator Lamp ( MIL) is part of the On -Board D iag ­
nos tic (O BD II) system. The symbol ligh ts up w hen the ign ition is
turned on and w ill tu rn off after the eng ine has star ted and has sett
led at constant idle speed . This i nd icates that the MIL is work ing
properly .
T he warn ing light ill uminates when there is a malfunction in the
engine e lectronic system. Contact yo ur a uthorized Audi dealer and
have the malfu nction co rrec ted .

On-Board Diagnostic system (OBD)
On-Board Diagnostics
Fig. 9 Location of
Data Link Connector
(DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each controlled component in your eng ine system
has been assigned a code. In case of a malfunction, the component
wi ll be identified and the fault stored as a code in the control module
memory .
The MIL lamp may also illuminate if there is a leak in the on-board
fuel vapor recovery system.
If the Light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed~
page 222.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the engine hood release lever~ fig. 9. Your authorized
Audi dealer or a qualified service station can inter­
pret the code and perform the necessary repair.•
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models )
The Malfunction Indicator Lamp (MIL) in the instrument cluster
~ page 11, fig. 5 is part of the On-Board Diagnostic (OBD II) system.
T he warn ing/indicator light illum inates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicates that the MIL is working properly .
If the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed limiter may also be
ma lfunction ing. For more information~
page 20, "E lectronic speed
limiter" .
An improperly closed fuel filler cap may also cause the MIL light to
illuminate~
page 222 . •
Electronic speed limiter
Your vehicle may be factory equ ipped with tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your veh icle . To reduce the risk of sudden tire
fai lure and loss of control if the vehicle is operated at excessive
speeds, your vehicle a lso has an electronic speed limiter . The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information~
page 259, "Speed rating
(letter code)".

• Th e fuse is "b lown" ::::, page 281, "R ep laci ng fuses".
• The wire connect io n to the light bulb is defective.
Have the bu lb rep lace d or the connec tion repa ired by your au thor ize d
Audi Service department.
& WARNING
• Light bulbs are pressurized and could e xplode while they are
being changed cau sing seriou s personal injur y.
• Work with due care when handling the high-voltage section of
ga s di scharge (xenon ) lamp s. Failing to do so could re sult in death

& WARNING
• The limit s of phy sics cannot be su spended by ESP. Even in vehi­
cles with ESP, you should always adapt your driving to road and
traffic conditions. Thi s is particularly true on a slippery and wet
road. Do not be tempted by the increased safety provided to take
ri sk s - danger of an a ccident!
• Please note that when ESP / ASR is deact ivated , the drive
