Auto Chec k Control
Some functions and vehicle components are
scanned for their operating status when yo u
switch the ignition on and whi le you are driving.
Malfunctions or required service procedures are
signaled audibly and indicated by red and yellow
illuminated symbols and reminders in the dis­
play.
A WARNING
--- Never rely exclusively on the outside tem­ pe ratu re d isplay to dete rm ine if a road sur­
face is icy or not. Keep in mind that road sur­
faces, espe cially bridges and overpasses,
could be ice covered and slippery even at an
outside temperature above 41 °f (+S °C).
- Always remember, even if the "snowflake"
symbo l (ice warning) does not appear in the
display, black ice cou ld be on the road .
-Always red uce your speed and d rive with
specia l care in cold weather conditions when
the chance of encountering icy road surfaces
increases.
(j) Tips
If the vehicle is stationary, or if yo u are driv­
ing at a very low speed, the temperature
shown in the disp lay might be slightly higher
than the actual outside temperature . This is
caused by the heat being radiated from the
engine.

Driver information system
On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢• in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system.
The warning/indicator light i lluminates when the
ignition is switched 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 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 acce lerations)
and have the condition corrected. Contact your
authorized Audi dealer.
I f the light illuminates, the electronic speed lim­
iter may also be malfunctioning. For more infor­
mation
c::> page 28, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c::> page 192.
On-Board Diagnostics
Fig. 16 Loca tion of Data Link Connec tor (DLC)
On-Board Diagnostics monito rs 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 .
28
The MIL light may also illuminate if there is a
l eak 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
c::> page 192.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using spec ia l diag­
nostic equipment (generic scan tool for 080).
In order to connect the specia l diagnostic equip ­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the r ight of the hood
release
c::> fig. 16.
Your authorized Audi dealer or qualified work­
shop can interpret the code and perform the nec­
essary 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 equ ipped with tires
that are rated for a maximum speed of 130 mph
(210 km/h) . This is may be less than the maxi­
mum speed of your vehicle. To reduce the risk of
sudden tire failure and loss of control if the vehi ­
cle is operated at excessive speeds, your vehicle
has an e lectronic speed limiter. The electronic
speed limiter prevents your vehicle from going
faster than the tire speed rating. For more infor­
mation
c::> page 209.
-
If the engine contro l unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Light (MIL)
II will illuminate. If this occurs, con­
tact the nearest author ized Audi dealer for assis­
tance.
A WARNING
Always observe the posted speed lim its 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 tires installed.
