On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) in the instrument cluster
=;,
page 12, fig. 7 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 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
malfunctioning. For more information=;,
page 26, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to illuminate

Vehicle care Do-it-yourselt service iTechnical data

Driver information display
On-Board Diagnostics monitors the components of your emission
control system. Each monitored component in your engine 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 light may also illuminate if there is a leak in the on-board fuel
vapor recovery system. If the light illumi nates after a refueling , stop
the vehicle and make sure the fuel filler cap is properly closed
=>
page 276.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan too l for
080).
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 hood release=>
page 25, fig. 20.
Your authorized Audi dea ler or qualified workshop can interpret the
code and perform the necessary repair. •
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 veh icle. To reduce the risk of sudden tire
fai lure and loss of control if the vehicle is operated at excessive
speeds, you r ve hicl e also has an electronic speed limite r. The elec­
tronic speed limiter prevents your vehicle from going faster than the
t ire speed rating. For more information=>
page 307.
If the eng ine control unit receives faulty veh icle road speed signals,
the Malfunction Indicator Lamp (MIL)
11.... will illuminate. If this
occurs, 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 maximum speed rating of the tires
installed. •
Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
The speed warning system warns if the driver exceeds a previous ly
sto red maximum speed. A warning tone will sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h). At the
same time, a warn ing symbol appears in the display. The symbol's
appearance might be different in some models.
Th e speed warning system has
two warning thresholds that function
independently of each other and that have somewhat different
purposes:
Speed warning 1
You can use speed warning 1 to set the maximum speed while you a re
driving . This setting w ill remain in effect until you turn off the igni­
tion, assuming that you have not changed or reset the setting .
Th e speed warning symbol
8 (USA models)/ 8 (Canada mode ls) in
the warning 1 display appears when you exceed the maximum speed.
It goes out when the speed falls below the stored maximum speed.
The speed warn ing symbol w ill also go out if the speed
exceeds the
stored maxim um speed by mo re than about 2S mph (40 km/h) for at
least 10 seconds . The stored max imum speed is deleted.
Setting speed warning 1 =>
page 27.

Speed warning 2
Storing warning 2 is recommended if you always want to be reminded
of a certain speed, for example when you are travel ing in a country
that has a genera l maximum speed limit, or if you do not want to
exceed a spec ified speed for winter tires.
The speed warning 2 symbol,
8. (USA mode ls)/ 8, (Canada models)
appears in the display when you exceed the stored speed limit. Unlike
warning 1, it will not go out until the vehicle speed drops below the
sto red speed limit.
Setting speed warning 2
=> page 27 .
00 Tips
Even though your veh icle is equ ipped with a speed warn ing system,
you should sti ll watch the speedometer to make sure you are not
driving faster than the speed limit.•
