On-Board Diagnostics
Fig. 15 Location of
Data Link Connector
(DLCl
On-Board Diagnostics monitors the components of your emission
control system . Each monitored 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 light may also illuminate if there is a leak in the on-board
fuel vapor recovery system. If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler cap is properly closed
~ page 305.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic 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 hood release
~ 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 338.
If the vehicle approaches the tire speed rating, the engine control
unit will turn off the fuel injectors. You will notice an immediate loss
of engine power and a drop in road speed.
If the engine control unit receives faulty vehicle road speed signals ,
the Malfunction Indicator Lamp (MIU 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 .....

Fuel supply and filling your fuel tank 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 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.
Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
& WARNING (continued)
• 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 F852-86l.
0 Note
If any fuel has spilled onto the car, it should be removed immedi -
ately to prevent damage to the paint. _.,
