On-Board Diagnostics
Fig. 4 Locat ion of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as
signed a code. In case of a malfunction, the com-
18
ponent will be identified and the fault stored as a
code in the control module memory.
The MIL light may also illum inate if there is a
l
eak in the on-boar d fuel vapor recovery system.
If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is
properly closed c:> page 233.
In order to make an accurate diagnosis, the stor
ed data can only be displayed using special d iag
nostic equipment (generic scan tool for OBD).
In order to connect the special 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. 4.
Your authorized Audi dealer or a qualified service
station can interpret the code and perform the
necessary repair.
11. WARNING
Do not use the diagnostic connector for per
sonal use. Incorrect usage can cause malfunc
tions, which can increase the risk of a colli
sion!

-If you a re unable to determine whether or
not a particular fuel blend
meets the speci
fications, ask your service station or its fuel
supplier.
-
Do not use fuel for which the contents can
not be identified.
- Fuel system damage and performance prob
lems resulting from
the use of fuels differ
ent from those specified are not the respon
sibility of
Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to
the use of one of these fuel blends, we
recommend
that you switch to unblended
fuel.
Gasoline additives
A major concern among many auto manufactur
ers
is carbon deposit build-up caused by the type
of gasoline
you use .
Although gasoline grades differ from one manu
facturer
to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine
parts, such as fuel injectors and intake valves.
Al
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas
oline.
For more information on TOP TIER Deter
gent Gasoline, please go to the official website
(www.toptiergas .com).
After an extended period
of using inadequate
fuels, carbon deposit build-ups can rob your en
gine of peak performance.
CD Note
Damage or malfunction due to poor fuel qual
ity
is not covered by the Audi New Vehicle
Limited Warranty.

Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind
the fuel filler flap.
If the power locking system should fail, you can
still open
the flap manually -for detailed instruc
tions see
~page 235.
You can find the fuel tank capacity of your vehicle
in ~page 299.
The label on the inside of the fuel filler flap tells
you
the correct fuel for your vehicle. For more in
formation about fuel specifications, see
~page 231.
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre
vent fuel vapors from escaping from
the tank and
polluting
the environment while you refuel your
vehicle .
In order to fill the tank properly while
protecting
the environment, please follow this
refueling procedure carefully.
.&. WARNING
Under normal operating conditions, never car
ry additional fuel containers in your car. Gas
canisters and other containers used to trans
port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers.
Make cer
tain the container
meets industry standards
(ANSI/ASTM F8S2 -86).
{[) Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply
of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.
