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
pre t the code and perform the necessary repair. •

Fuel supply and filling your fuel tank
Taking the fuel cap off
- To open the fuel filler flap, pull the button~ page 269,
fig. 200.
- Unscrew fuel filler cap counter-clockwise and hang it on the fuel filler flap.
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 the MIL lamp => page 27to 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 car's filler neck could cause fuel
overflow and fuel spray. Fuel spray and overflowing fuel are
dangerous because they can cause fire or serious injury.
& WARNING (continued)
• 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 .
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
~

/b, WARNING (continued)
-Make certain the fuel container meets industry standards
(ANSI / ASTM F852-861.
0 Note
If any fuel has spilled onto the car, it should be removed immedi­
ately to prevent damage to the paint.
ffi For the sake of the environment
As soon as the correctly operated no zzle switches off automatically
for the first time, the tank is full. Do not try to add more fuel because
fu el 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 o therwise not indicate the correc t fuel level after
refuelling. •
Unlocking the fuel filler f lap by hand
You can open the fuel filler flap by hand if the power
locking system should fail.
