On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Ma lfunction Indicator Lamp (MI L) ¢,ij in the
inst rument cluster is part of the On-Boa rd Diag­
nostic (OBD II) system .
T he wa rning/indicator light ill uminates when the
ignition is sw itched 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 li ght do es not go out after the eng ine is
sta rted, or i lluminates while you are driving, a
malfunction may exist in the engine system. If
the lig ht illuminates, the catalytic converter
could be damaged.
Cont inue driving
with reduced power (avoiding
s ustained high speeds and/o r rapid accelera­
tions) and have the condit ion corrected. Contact
your authori zed Aud i dea ler .
If the light i llum inates, the elect ronic speed lim­
iter may also be malf unct ion ing. For more infor­
mation

Cockpit overview
On-Board Diagnostics
Fig. 19 Location 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
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
leak 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
¢ page 269.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
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
¢ fig. 19.
Your authorized Audi dealer or a qualified service
station can interpret the code and perform the
necessary repair.
A 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!
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
26
failure and loss of control if the vehicle is operat­
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
¢ page 290.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢'4 will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
ass istance.
58
Your vehicle's top speed is electronically limited
to 155 mph (250 km/h).
If the engine control unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Lamp (MIL)
¢'4 will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
assistance.
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your vehicle faster than the maximum speed rating
of the ti res installed.

(D Tips
-The light sensor* for automatic dynamic
headlight range control* is located in the
rear view mirror mount . You should there­
fore not apply any stickers to the windshield
in this area in order to prevent malfunctions
or failures .

the driver is notified in the instrument clus­
ter display~
page 25.
- You will hear a warning tone if you open the
driver door when the exterior lights are
switched on.
- In cool or damp weather, the inside of the
headlights, turn signals and tail lights can
fog over due to the temperature difference
between the inside and outside. They will
clear shortly after switching them on. This
does not affect the service life of the light­ ing .

on v is ibility conditions .
- The w indshield may not be treated with wa­
ter-repelling windsh ield coating agents . Un­
favorable conditions, such as wetness, dark­ ness, and when the sun is low, can cause in­
creased g lare, which increases the risk of an

- If there is frost, make su re t he windshie ld
wiper blades are not fro zen to the wind­
shield. Sw itching on the windshield wipers
when the blades are frozen to the wind­
shield can damage the wiper blades.
- Prior to using a car wash, the windshield
wiper system must be switched
off (lever in
pos ition
@ ). This prevents the wipers from
switching on un intent ionally and causing
damage to the w indshield w iper system .
