On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 19, fig. 9 is part of the On -Board Diagnostic (OBD II) system.
The warning/indicator light il luminates 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 prope rly.
If the light do es 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 starts flashing, the catalytic converter could be damaged .
Continue driving
w ith redu ced pow er (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected. Contact your authorized Audi dealer.
If the light illuminates, the e lectronic speed limiter may also be
malfunctioning . For more

On-Board Diagnostics monitors the components of your emission
control system . Each control led component in your engine system
has been assigned a code. In case of a malfunction, the component
wil l be identified and the fault stored as a code in the control
modu le memory.
The M IL lamp may a lso 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 fi ller
cap is proper ly closed
=> page 269.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnos tic 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. 15 .
Your author ized Audi dealer or a qua lified service station can inter­

Electronic speed limiter
Your vehicle may be factory equipped with 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 limiter . The elec ­
tronic speed limiter prevents your vehic le from going faster than the
tire speed rating. For more
information~ page 305, "New tires and
r eplacing tires and wheels" .
If the vehicle approaches the tire speed rating, the engine control
unit wi ll turn off the fuel injectors. You will notice an immediate loss
of engine power and a drop in road speed.
If the engine control unit receives faulty vehicle road speed signals,
t he Malfunc tion Indicator Light (MIU will illuminate. If this occurs,
contact the nearest authorized Audi dea ler for ass istance.

Introduction
T he tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the tire pressure monito ring system se nses a significant
loss of air pressure in one or several tires, text messages and yel low
symbo ls appear in the instrument clus ter disp lay to a lert the driver.
The
(l) warning light in the instrument cluster comes on when the
t ire is significa ntly under inflated.
The warning light
(l) also lights up during a system failure .
When the whee l is turning, the system receives radio signals from
sensors located inside each tire.
A factory spare wheel is delivered with sensor . However, the spare
whee l is not checked by the ti re pressure monitoring sys tem. Such
monitoring can on ly occur after the spare wheel has been insta lled
and
initia lized => page 50.
Be aware that t ire pressure is a lso dependent o n the temperature of
the tire . For every 18 °F (1
O °C) increase in tire temperature, tire pres ­
su re increases by about 1.5 psi (0 .1 barl. The tire warms up wh ile the
vehic le is moving and t ire pressure rises. So you should adjust tire
pressure only when they are
cold, when tire temperature is roughly
the same as ambient air temperature .
I n order to keep the tire pressure moni toring system prope rly ca li­
brated, tire pressure on all four tires shou ld be checked at regular
intervals, adjusted if necessary and saved in the proper sett ing
(reco mmended
pressure) => page 48.
The tire pressure is shown on the tire pressure label. On USA vehi ­
cles, the tire pressure label is located on the dr iver's side B -pillar. On
Canada vehicles, the tire pressure labe l is located either on the
driver's side B -p illar o r inside the fue l fi ller flap. The tire pressure
label l ists the recommended cold tire inflation pressures for the
vehic le at its maximum capacity weight and the tires that were on
your vehicle at the t ime it was manu factured . For recommended tire

[ i ] Tips
• In the case of an intentional loss of air pressure, for examp le,
when re -adjusting tire pressure, this has to be stored again after ­
wards~ page 48.
• Tire pressure must only be adjusted when the temperature of the
t ires is about the same as ambient air temperature.
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is s tored in the system
~ page 48 .
• After changing a wheel you have to adjust the tire pressures on
all wheels. In addition, you must then initia lize the new tire pres­
sures in the tire pressure monitoring
system ~ page 50. •

additional ly the => fig. 44 symbol appears in the display, the
tire pressure monitoring system is not available . This can have
various causes.
• If the message appears at the end of the learning phase, the
system cannot recognize the wheels insta lled on the vehicle . This
can be because one or more wheels without a wheel sensor were
installed .
• A wheel sensor or other component may have failed.
• The system has detected more than 4 wheels in the vehicle, for
example while driving beneath another car with tire pressure moni ­
toring system .
• A tire was changed but
the => page 50, "Changing a wheel"
procedure was not activated
=> page 50.
• Audi replacement parts were not used .
• If snow chains are being used , system function can be compro ­
mised due to the shie lding properties of the chains .
• The tire pressure monitoring system may not be available
because of a radio malfunction .
• Transmitters with the same frequency , such as radio head ­
phones in the vehicle or radio equipment, can cause a temporary
dis ruption of the system through excessive el ectromagn etic fie lds.
• Try to find the cause of the interference, and then perform the
=> page 50, "Changing a wheel" procedure one more time . If this not
e liminate the prob lem , contact your authorized Audi dea ler for
assistance .
• Do not use commercially available tire sealants. Otherwise , the
electrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system will have to be replac ed by a qualified workshop. •

[ i] Tips
• Do not attach any stickers to the windshield in front of the two
light sensors, as this would interfere with both the automatic oper ­
ation of the headlights and the automatic dimming of the inside
mirror(sl.
• If the vehicle is remotely unlocked and locked
three times in
succession,
leaving home will not turn on the lights a fourth time to
safeguard the battery and lights .
• If you wish to use the coming home/leaving home function regu ­
larly, you can leave it activated at all times without risking perma­
nent strain on the electrical system. As the system is controlled by
light sensors, it wi ll only be energized in darkness.
• Frequent use of the coming home/leaving home function for
approaching and departing a vehicle parked in the dark wil l strain
the battery. This applies particularly if only short distances are
driven between stops . Occas ionally drive longer distances to make
sure the battery is recharged sufficiently.
• If the fog lights have been switched on by the coming
home/leaving home function, they will always be switched off when
you switch on the ignition .•
