On-Board Diagnostic system (OBD)
On-Board Diagnostics
Fig. 9 Location of
Data Link Connector
(DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each controlled component in your eng ine system
has been assigned a code. In case of a malfunction, the component
wi ll be identified and the fault stored as a code in the control module
memory .
The MIL lamp may also 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 filler
cap is properly closed~
page 222.
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 engine hood release lever~ fig. 9. Your authorized
Audi dealer or a qualified service station can inter­
pret the code and perform the necessary repair.•
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models )
The Malfunction Indicator Lamp (MIL) in the instrument cluster
~ page 11, fig. 5 is part of the On-Board Diagnostic (OBD II) system.
T he warn ing/indicator light illum inates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicates 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 accelerations) and have the condition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed limiter may also be
ma lfunction ing. For more information~
page 20, "E lectronic speed
limiter" .
An improperly closed fuel filler cap may also cause the MIL light to
illuminate~
page 222 . •
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). This is less than the
maximum speed of your veh icle . To reduce the risk of sudden tire
fai lure and loss of control if the vehicle is operated at excessive
speeds, your vehicle a lso 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 259, "Speed rating
(letter code)".

Some states in the USA require permits to purchase diesel fuel. Check
with your State Motor Vehicle Department.
Diesel fuel may not be available outs ide the USA and Canada. Be sure
to check before traveling to other countries .
Winter operation
At temperatures below 20° F (- 7° C), Diesel fue l No. 2 loses its fluidity
due to wax separation, which may clog the fuel filter or tank filter and
keep the engine from running.
T o help the filter from being clogged by wax, the fuel fi lter in your
vehicle is automatically preheated. Preheating the fuel filter makes
operat ion of your vehicle possib le with Diesel fuel No. 2 down to -
10° F (-24° C).
If you expect temperatures below 5° F (-15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is suffic iently w interized for the
prevailing and expected temperatures.
If not winte rized or insuffic iently winterized diesel fuel has already
thickened to the extent that the engine will not start, warm the
vehicle up by leaving it in a heated garage.
It is normal that the engine noise level (dieseling) is louder during the
warm-up period in winter.
It is also normal when whitish -blue smoke
comes out of the tailpipe after start ing and during warm-up. The
amount of smoke depends on the outside temperature.
Do not let your diese l engine id le unnecessari ly after a cold start.
Driving off slowly will shorten the warm-up period.
& WARNING
• Never use "starting assist fluids." They may be potentially
explosive or cause a "run-away" engine condition. This could
result in serious engine damage and personal injury.
• Never use fuel line anti-freeze offered for gasoline engines.
Safety first
0 Note
• Your diesel engine has been specifically designed to operate only
on Ultra Low Sulfur Diesel fue l. Therefore, never use home heating oil
or regu lar gaso line. The properties of these fuels may cause serious
damage to the fuel injection system and to the engine. Using these
fue ls can cause expens ive eng ine repairs and will also adversely affect
your New Vehicle Limited Warranty.
• If diesel fuel should get on any rubber hose, it must be wiped off
immediately. Then wash the contaminated hose portion with soap
and warm water. Do not allow diesel fuel to rema in on connecting
hoses. They may deve lop leaks and cause serious damage. •
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear side panel behind the
fue l filler flap.
If the power locking system should fa il, you can still open the flap
manually - for detai led instructions see=>
page 224.
You ca n find the fuel tank capacity of your vehicle in Technical Data
=> page 296 .
The label on the inside of the fue l filler flap tells you the correct fuel
for your veh icle. For more information about fuel specifications, see
=> page 219.
Your vehicle fuel tank has an on-board refuelling vapor recovery
system . This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment while you refuel your vehicle.
In order to fill the tank properly while protect ing the environment,
please follow this refueling procedure carefully. .,,

& WARNING
Under normal operating conditions, never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport 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, trans ­
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI/ASTM F852 - 86).
0 Note
Never drive your vehicle until the fuel tank is completely dry. The
irregular supply of fuel can cause misfiring. Gasoline could enter into
the exhaust system and damage the catalytic converter. •
Refuelling
The fuel filler flap is unlocked from a button in the
driver's door.
Fig . 156 Driver's
door: Unlocking fuel
filler flap Fig
. 157 Fuel cap
hooked on the opened
fuel filler flap
When adding fuel, the ignition and any cellular phones in the
vehicle must be switched
off.
Taking the fuel cap off
- To open the fuel filler flap, pull the button=> fig. 156 .
- Unscrew fuel filler cap counter-clockwise and hang it on
the fuel filler flap => fig . 157.
- Check the label on the inside of the fuel filler flap to deter­
mine if the vehicle must be fueled with gasoline or diesel
fuel.
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. .,

Fuel supply and filling your fuel tank
(I) Tips
• Runn ing your eng ine 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 fu ll.
• Do not refuel your vehicle with the ignition switched on. The fuel
gauge may otherwise not ind icate the correct fuel level after
refuelling. •
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the power
locking system should fail.
- Open the rear lid.
