On-Board Diagnosti cs
Fig . 15 Location of
Data Link Connector
(DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each controlled component in your engine system
has been assigned a code. In case of a malfunction, the component
will be identified and the fault stored as a code in the control module memory .
Th e 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 246.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBDl.
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 authorized Audi dealer or a qualified service station can inter ­
pret 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 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 vehicle from going faster than the
tire speed rating. For more information=>
page 279, "New tires and
replacing tires and wheels".
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfunction Indicator Lamp (Mill 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. •
Auto-Check Control
Introduction
The Auto-Check control monitors the function of certain vehicle
features and components. It simply makes sure these features and
components are working properly. The Auto-Check control works as
long as the ignition is on, as well as whenever the vehicle is driven.
If a component is malfunctioning or if the need for an urgent repair
has been detected, this will appear in the instrument cluster display.
You will also hear an audible warning tone. The displays are color
coded in either red or yellow depending on their level of priority. .,_

and severe burns .
• Fuel is highly flammable and can cause severe burns and other
injuries .
• Failure to shut the engine off while refueling and /or to insert
the pump nozzle fully into the fuel filler ne ck could cause fuel to
spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire .
• Never use a cellular telephone while refueling . The electromag ­
netic radiation can cause sparks that can ignite fue l vapors and
c ause a fire .
• Never get ba ck into your vehicle wh ile refueling . If in e xcep ­

Fu el supply and filling your fu el tank
& W ARNING (continued )
Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
• For your safety , we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container , full or
empty may leak and could cause a fire , especially in a crash .
• If, under e xcept ional circumstances , you must transport a
portable fuel container, please observe the following:
-Never fill a portable fuel container while it is anywhere
in or
on the vehicle (for example , in the luggage compartment , or on
the trunk) . Static electricity can build up while filling and can
ignite fuel vapors causing a fire.
- Always place a portable fuel containe r on the ground before
filling.
- Always keep the filler nozzle completely inside the portable
container before and during filling .
- If filling a portable container made of metal , the filler nozzle
must always be in contact with the container. Thi s will help
prevent static ele ctricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment .
Fuel vapors are h ighly flammable .
- Always observe local and state/provincial laws regarding the
use , storage and transportation of fuel conta iners.
- Make certain the fuel container meets indu stry standards
(ANSI / ASTM F852-86).

ate ly to prevent da mage to the pa int. _,.
Vehic le care

Fuel supply and filling your fuel tank
ffi For the sake of the environment
As soon as the correctly operated nozzle switches off automatical ly
for the first time, the tank is full. Do not try to add more fuel because
fuel may spill out. In addi tion, the expansion space in the fuel tank
will be filled -causing the fuel to overflow when it becomes warm
and po llute the environment.
[ i ) Tips
• Running your engine while refuelling may cause vapors to
escape or even cause fuel to spill out of the tank. This would then
shut off the fue l nozzle before the tank is full.
• Do not refuel your vehicle with the ignition turned on. The fuel
gauge may otherwise not indicate the correct fuel level after
refuelling. •
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the power
locking system should fail .
