On-Board Diagnostics

Data Link Connecto r
( DL C)
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 .
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 227.
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 re lease lever=>
page 21, fig. 10 .
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 (MIU in the instrument cluster
=> page 17, fig . 5 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 ma lfunction may exist in the engine system.
If the light starts flashing, the catalytic converter cou ld 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 27, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate => page 221. •
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, yo ur 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 257, "Speed rating
(letter code)".
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfun cti on Indicator Light (MIU will illuminate . If this
occurs, contact the nearest authori zed Audi dealer for assistance. _.,

Your vehicle fuel tank has an on -board refuelling vapor recovery
sys tem. Th is feature helps to prevent fue l vapors from escapin g
from the tank and polluting the environment wh ile you refue l your
veh ic le . I n order to fill the tank properly while protecti ng the envi
ronment, please follow this refuel ing procedure carefully .
& WARNING
Under normal operating conditions , never carry additional fuel
c ontainers in your car . Ga s canister s and other containers used to
transport fuel can be dangerous . Such conta iners , full or empty,
may leak and could cause a fire in a collision . If you mu st transport
fuel to use for your l awn mower , snow blower , etc. , be very c areful
and always ob serve local and state laws regarding the u se , tran s
port ation and storage of su ch fuel containers . Make certain the
c ontainer meets industry standard s (ANSI/ASTM F852 · 86 1.

Refuelling procedure
-Insert the fuel nozzle from the gasoline pump into the
fuel filler neck as far as it will go.
- Select a medium refuelling rate so that the nozzle switches off automatically when the tank is full.
Putting the fuel cap back on
- After filling your tank, twist the fuel filler cap clockwise
until you hear a definite click.
Close the fuel filler flap.
To avoid fuel spilling or evaporating from the fuel tank always close
fuel filler cap properly and completely. An improperly closed fuel
filler cap may also cause a message in the driver information system
or cause th e MIL lamp => page 21 to come on.
& WARNING
Improper refueling or handling of fuel can cause fire, explosion
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 neck 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 fuel vapors and
cause a fire.
• Never get back into your vehicle while refueling.
If in excep
tional circumstances you must get back in your vehicle while refu eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
& WARNING (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 exceptional 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 container 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. This will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment. Fuel vapors are highly flammable .
- Always observe local and state/provincial laws regarding the
use, storage and transportation of fuel containers.
- Make certain the fuel container meets industry standards
(ANSI / ASTM F852-861.
(D Note
If any fuel has spilled onto the car, it should be removed immedi -
ately to prevent damage to the paint.

Fuel supply and filling your fuel tank -------------=-=--=-------=:a....:.--------J
<£> For the sake of the environment
As soon as the correctly operated nozzle switches off automatically
for the first time, the tank is full. Do not try to add more fuel because
fuel may spill out. In addition, the expansion space in the fuel tank
will be filled -causing the fuel to overflow when it becomes warm
and pollute the environment.
[ i] Tips
• Running your engine while refuelling may cause vapors to
escape or even fuel to spill out of the tank. This would then shut off
the fuel nozzle before the tank is full.
• Do not refuel your vehicle with the ignition switched on. The fuel
gauge may otherwise not indicate the correct fuel level after
refuelling. •
Unlocking th e fuel filler flap by hand
You can open the fuel filler flap by hand if the power
locking system should fail.
