On-Board Diagnostics
Fig. 22 Locat ion of Data Link Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your emission control system. Each
monitored component in your engine system
has been assigned a code . In case of a mal­
function, the component will be ident ified
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 fue l vapor recovery sys­
tem.
If the light illuminates after a refuelling ,
stop the veh icle and make sure the fuel filler
cap is proper ly closed (on ly vehicles with gaso­
line engine)
¢page 253.
In o rder to make an accurate d iagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBD).
I n o rder 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¢
fig . 22.
Your author ized Audi dealer or qualified work­
shop can interpret the code and perform the
necessary repair.
A WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
ma lfunctions, which can increase the risk
of a collis ion!
Electronic speed
limiter
Your vehicle may be factory equipped w ith
t ir es 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 fa ilure a nd loss of contro l if
the vehicle is operated at excessive speeds,
your vehicle also has an elec tronic speed limit­
er . The e lectronic speed limiter prevents your
vehicle from going faster than the tire speed
rating . For more information ¢
page 285.
If the engine control unit receives faulty vehi­
cle roadspeed signals, the Malfunction Indica ­
tor Lamp (MIL)
II will ill uminate. If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.
A WARNING
-
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather cond itions . Never
drive your vehicle faster than the maxi­
mum 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.
T he speed warning system warns the driver if
he exceeds a previo usly stored maximum
speed . A warning tone wi ll so und as soon as
the vehicle speed exceeds the set speed by about 3 mph (3 km/h). At the same time, a
warning symbol appears in the display.
The 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 maxi­
mum speed while you are driving. This setting "'

container meets industry standards (ANSI/
ASTM F852 -86).
(D Note
Never drive yo ur vehicle unt il the fuel tank
is complete ly empty. The irregular supply
of fuel can cause misfiring . Gasoline could
enter the exhaust system and damage the
catalyt ic converter.
Refuelling
F ig. 220 Righ t rear vehicle side: Opening th e fue l fill er
flap
F ig. 221 Fu el cap hooked on the opened fuel filler flap
When adding fuel, the ignition and any cellu­
lar phones in the vehicle must be sw itched
off. When activating the central locking, the
fuel filler flap is automatica lly unlocked or
locked. Refuel the ve hicle w ith the ignition
turned
off.
Tak ing th e fu el cap off
• To open the fuel filler flap, press on the left
s ide of the flap¢
fig. 220 -arrow- .
• Unscrew fuel fil ler cap counter-clockwise
and hang it on the fuel fille r flap ¢
fig. 221.
• Check the label on the inside o f the f uel fill­
er flap to determine if the vehicle must be
fueled with gasoline or diesel fuel.
Fuel suppl y and filli ng your fuel t ank 25 3
Refuelling p ro cedur e
• Insert the fuel nozz le from the gasoline
pump into the fuel fi ller neck as far as it wi ll
go .
• Select a medi um refue lling rate so that the
nozz le switches off automatically when the
tank is full.
Pu tting th e fuel cap bac k on
• After fi lling your tank, twist the fuel filler
cap clockwise as far as it wi ll go.
• Close the fue l filler flap.
T o avoid fuel spill ing or evaporating from the
fuel tank always close fuel filler cap proper ly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 2 7
to come on (only vehicles with gasoline en­
gine).
A 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 injur ies.
- Failure to shut the engine off wh ile refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l to spray out of filler neck or to over­
f low. Fue l spray and overflowing fue l can
cause a fi re.
- Never use a cel lu lar telephone while re­
fueling. The electromagnetic rad iation
can cause sparks that can ignite f uel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fueling. If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
stat ic electricity before touching the fill­
er nozzle again. Static e lectricity can
cause sparks that can ignite fuel vapors re leased du ring refuel ing .
- Never smoke or have an open flame any­
where in or near your veh icle when refu-
eling or filling a portab le fue l conta iner.

- For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con­
tainer, 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 portab le fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk). Static electrici­
ty can build up while filling and can ig­ n ite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
-Always keep the fi ller nozzle complete­
ly 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 dis­
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transpo rtation of fuel conta iners.
- Make certa in the fuel container meets
industry standards (ANSI/ ASTM
F8S2-86).
@ Note
If any fuel has spilled onto the car, it
should be removed immed iately to prevent
damage to the paint .
@) For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the first
time, the tank is full. Do not try to add
mo re fuel because fuel may spill out. In
add it ion, the expans ion space in the fuel
tank will be f illed -causing the fue l to overflow when it becomes warm and pol­
lute the environment .
(D Tips
-Running your engine whi le refue lling
may cause vapors to escape or even
cause fuel to spi ll out of the tank. This
would then shut off the fue l nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion turned on. The fuel gauge may oth­
erwise not indicate the correct fuel level
after refuelling.
- Diesel vehicles* are equipped with a die­ sel misfueling protector. It allows the
vehicle to be fueled only with a diesel
fuel pump nozzle. A worn or damaged nozzle or a nozzle that is too small may
not be ab le to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before insert ing it in the f uel
filler neck, use a different fuel pump or
see your authorized Audi dea ler or au­
thorized repair facility for assistance.
