On-Board Diagnostic
system (OBD)
On-Board Diagnostics
Fig. 25 Locat ion of Data Link Connecto r (DLC)
On-Board Diagnostics monitors the compo­
nents of you r emission control system. Each
monitored compo nen t in your eng ine system
has been assigned a code . In case of a ma l­
function, the component will be identified
and the fau lt stored as a code in the control
module memory.
The MIL light may a lso 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 vehicle and make sure the fuel filler
cap is properly closed ¢
page 176.
In o rder to make an accurate diagnosis, the
stored data can only be displayed using spe­
cia l 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. 25.
Your authorized Audi dea ler or a qualified
service station can interpret the code and per­
form the necessary repair .
Malfunction Indicator lamp (MIL)
The Malfunction Indicator Lamp (MIL) &'I in
the instrument cluster¢
page 13, fig. 6 is
part of the On-Board Diagnostic COBO II) sys­
tem .
The warning/indicator light illuminates when
the ignit io n is switched on and goes out after
the e ngine starts and the idle has stabilized.
Th is indicates that the MIL is working prope r­
ly.
If th e light d oes not go out after the engine
is started, or illum inates wh ile you are dr iv­
ing, a malfunc tion may exist in the engine sys­
tem.
If the light illum inates, the catalytic con­
verte r could be damaged .
Continue driving
with reduced p ower (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact you r authorized Audi dea le r.
If the light illum inates, the electronic speed
limi ter may also be malfunct ioning . For more
i nformation ¢
page 28, Electronic speed
limiter.
An improperly clo sed fu el filler cap ma y also
cau se the MIL light to illuminate
¢ page 176.
Electronic speed limiter
Your vehicle may be factory eq uipped w ith
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 fai lure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle a lso has an electronic speed limit­
er . The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating. Fo r more information

than 3 seconds and faster than 3 mph (5 km/
h).
A WARNING
-Always observe the warnings in
9 page 172, Engine compartment, be­
fore opening the engine hood and check­ ing the brake flu id .
- Driv ing with low brake fluid is a safety
hazard! Stop the car and get professional
assistance.
- If the brake system warn ing/ indicator
light illuminates together with the ABS
warning/ind icator light, t hen the ABS
system is malfunct ion ing . The rear
wheels co uld qu ickly lock up when yo u
apply the brakes. This could lead to loss
o f control and your vehi cle could slide!
Drive carefu lly to the nearest a uthorized
Audi dealer and have the ma lfunction
corrected.
_ L Engine cooling system
A malfunction in the engine cooling system
must be repaired as soon as possible .
When the . symbol in the d isp lay flashes,

s istance if necessary.
If the engine coolant level is correct, then the radiator fan may be the cause of the malf unc­
tion .
If the generator wa rning/ind icator light
should also illuminate ¢
page 16, then the
fan belt may be damaged.

Pollutant filter
The pollutant filter (particle filter) ensures
that contaminants in the outs ide a ir (such as
dust or pollen) are greatly reduced or stop­ ped . T he air is also f iltered in recircu lation
mode .
The pollutant filter element must be changed
according to the intervals specified in the
maintenance schedule so that the air condi ­
tioning system's performance is not adversely
affected.
If the filter's effect iveness is weakened by
d riving the vehicle in areas with heavily pollut ­
ed outside air, the filt er element should also
be cha nged in between the listed services.
.&, WARNING
For safety reasons, i t is impo rtant t hat all

sa tion . Only then is good visib ility ensured .
Please familiarize yourse lf wit h the co rrect
operation of the air conditioning and how

& WARNING
Improperly worn safety belts increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- Always make sure that all vehicle occu­
pants are correctly restrained and stay in
a correct seating position whenever the
vehicle is being used.
- Always read and heed all WARNINGS and
other important information
Q page 109.
Safety belt preten­
sioners
How safety belt pretensioners work
In front and side collisions above a particular
severity, safety belts in use are tensioned au­
tomatically.
The safety belts are equipped with safety belt
pretensioners. The system is activated by sen­
sors in front and side collisions of great se­
verity. This tightens the belt and takes up belt
slack
Q &. in Service and disposal of safety
belt preten sioner on page 113.
Taking up the
slack helps to reduce forward occupant move­
ment during a collision .
@ Tips
The safety belt pretensioner can only be
activated once.
- In minor frontal and side collisions, in
rear-end collisions, in a rollover and in
accidents involving very little impact
force, the safety belt pretensioner are not activated.
- When the safety belt pretensioner is ac ­
tivated, a fine dust is released . This is
normal and is not caused by a fire in the
vehicle.
- The relevant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped. A
qualified dealership is familiar with
these regulations and will be pleased to
pass on the information to you.
Safety belts 113
-Be sure to observe all safety, environ­
mental and other regulations if the vehi­
cle or individual parts of the system, par­
ticularly the safety belt or airbag, are to be disposed. We recommend you have
your authorized Audi dealer perform this service for you.
Service and disposal of safety belt
pretensioner
The safety belt pretensioners are parts of the
safety belts on your Audi. Installing, remov­
ing, servicing or repairing of belt pretension­
ers can damage the safety belt system and
prevent it from working cor rectly in a colli­
sion.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and tha t dis­
carded componen ts do no t cause injury or pol­
lute the environment .
& WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing a safety belt
pretensioner from activating when needed
or activating it unexpectedly :
- The belt pretensioner system can be acti­
vated only once. If belt pretensioners
have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety belt system .
- Safety belt systems including safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposal of this system.
- For any work on the safety belt system,
we strongly recommend that you see
your authorized Audi dealer or qualified
technician who has an Audi approved re­ pair manual, training and special equip­
ment necessary . •
