On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢• in the
instrument cluster
c:::> page 14, fig. 8 is part of the
On-Board Diagnostic (OBD II) system.
The warning/indicator light i lluminates when the
ignition is switched on and goes out after the en
gine starts and the idle has stabilized. This indi
cates 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 acce lerations)
and have the condition corrected. Contact your
authorized Audi dealer.
I f the light illuminates, the electronic speed lim
iter may also be malfunctioning. For more infor
mation

An improperly closed fuel filler cap may also
cause the MIL light to illuminate (only vehicles
with gasoline engine)

On-Board Diagnostics
F ig . 21 Locat ion of Data link Connector (DLC)
On-Board Diagnostics monitors the components
of yo ur emission control system. Each monitored
component in your engine system has been as
signed a code . In case of a malfunction, the com
ponent will be identified and the fault stored as a
code in the control module memory.

The MIL light may also illuminate if there is a
l eak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop
erly closed (only vehicles with gasoline engine)

In order to make an accurate diagnosis, the stor
ed data can only be displayed using specia l diag
nostic equipment (generic scan tool for OBD).
In order to connect the specia l diagnostic equip
ment, push the plug into the Data Link Connector
(DLC) . The DLC is located to the right of the hood
release
c::> fig. 21.
Your authorized Audi dealer or qualified work shop can interpret the code and perform the nec
essary repair .
A WARNING
Do not use the diagnostic connector for per
sonal use. Incorrect usage can cause malfunc
tions, which can increase the r isk of a coll i
sion!
Electronic speed limiter
Your vehicle may be factory equ ipped with tires
that are rated for a maximum speed of 130 mph
(210 km/h) . Th is is less than the max imum speed
of your veh icle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is ope rat
ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
limiter prevents your vehicle from going faster
than the tire speed rating. For more information
c::> page 242.
If the engine contro l unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL) ¢•will illuminate. If this occurs,
contact the nearest authorized Audi dealer for as
sistance.
SQS
Your vehicle's top speed is electronically limited
to 155 mph (250 km/h).

Static electricity can cause sparks that can ignite fuel vapors released during refueling.
- Never smoke or have an open flame any
where in or near your vehicle when refueling or filling a portable fuel container.
- For your safety, we strong ly 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 whi le it
is anywhere in or on the vehicle (for exam
ple, in the luggage compartment, or on
the trunk). Static electricity can bui ld 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 fi ller nozzle complete ly
ins ide the portable container before and
during filling.
- If filling a portable container made of
metal, the filler nozz le must always be in
contact w ith the container . Th is will help
prevent static e lectricity from discharg ing
and cause a fire .
- Never sp ill fuel inside the vehicle or lug
gage compartment. Fue l vapors are highly
flammab le.
- Always observe local and state/provincial laws rega rding the use, storage and trans
portat ion of fuel contai ners.
- Make certa in the fuel container meets in
dustry standards (ANSI/ ASTM F852 -86) .
(D Note
If any fuel has spilled onto the car, it shou ld
be removed immediately 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 more fuel
Fu el a nd R efu elin g
because f uel may spill out. In addition, the
expansion space in the fuel tank will be fi lled -
causing the fue l to overflow when it becomes
warm and pollute the environment.
@ Tips
- Running your engine whi le refue lling may
cause vapors to escape or even cause fue l to
spill out of the tank. This would then sh ut
off the fuel 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 refu
elling .
- Diesel vehicles* are equipped with a diesel
m isfueling protector .
It allows the vehicle to
be fueled only with a d iesel fue l pump noz
zle . A wo rn o r damaged nozzle o r a nozz le
that is too small may not be able to open
the diesel misfueling protector.
If this is the
case , try turning the nozzle before insert ing
it in the fuel filler neck, use a different fuel
pump or see your authorized A udi dealer or
authorized repair facility for assistance.
- The fuel fi ller f lap of your vehicle is not
locked when you lock the vehicle from the
inside.
Unlocking the fuel filler flap
by hand
You can open the fuel filler flap by hand if the
power locking system should fail.
