Service inquiry (distance remaining )
The distance remaining to the next service event can be displayed
in the MMI => fig. 14. The distance remaining is updated each time the ignition is switched on, the first time after 310 miles (500 kilome­
t
ers).
If the distance remaining is queried on new vehicles or after service
has been performed, the due date within the first 310 miles (500
kilometers) is always shown in the display with the following
message.
SERVICE IN ----- MILES (KM) ---DAYS
Service reminder
30 days before the next service is due, a service reminder appears
in the display when you turn on the ignition=> fig. 15.
After about 5 seconds the display switches back to normal. The
distance and time remaining are updated each time the ignition is
turned on until the date due for service is reached.

If you disconnect the battery terminals, no calculations can be
made for the service interva l display during this time and no service
reminder will appear. Remember that observing the proper service
interva ls is vitally important to extending the life of your vehicle,
particularly the engine, and maintaining its value. Even if the
mileage driven is low, the maximum period of one year from one
service to the next must not be exceeded.•

On-Board Diagnostic system (08D)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU ~ in the instrument cluster
~ page 17, fig. 7 is part of the On-Board Diagnostic (OBD ID system.
The warning/indicator light illuminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabi lized . 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 starts flashing, 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
malfunctioning . For more information~
page 29, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
~ page 327. •
On-Board Diagnostics
Con tro ls and eq uip­
ment
Fig . 16 Location of
Data Link Connector
(D LC )
Driver information display
On-Board Diagnostics monitors the components of your emission
control system. Each monitored component in your engine sys tem
has been assigned a code. In case of a malfunction, the component
wil l be identified and the fault stored as a code in the control
module memory .
The M IL light may also illuminate if there is a leak in the on -board
fuel vapor recovery system. If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler cap is properly closed
~ page 327.
In order to make an accurate diagnosis, the stored data can only be
d isplayed using special diagnostic equipment (generic scan tool for
08D).
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 hood release~ fig. 16.
Your authorized Audi dealer or qualified workshop can interpret the
code and perform the necessary repair. •
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
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also 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 359.
If the engine control unit receives faulty vehicle roadspeed signa ls,
the Malfunction Indicator Lamp (MIU will i lluminate . If this
occurs, contact the nearest authorized Audi dealer for assistance. .,.

& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road, traffic and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires
installed. •
Auto Check Control
Introduction
The Auto -Check control monitors the function of certain vehicle
features and components . It simply makes sure these features and
components are working properly . The Auto -Check control works as
long as the ignition is on, as well as whenever the vehicle is driven.
If a component is malfunctioning or if the need for an urgent repair
has been detected, this will appear in the instrument cluster display.
You will also hear an audible warning tone . The displays are color
coded in either red or yellow depending on their level of priority .
A red symbol means
Danger, a yellow symbol indicates Warning. In
certain situations, information message for the driver appear in
addition to the red and yellow symbols.
Function test: automatic transmission
The Auto-Check Control will automatically perform a test each time
you switch on the ignition. With the selector lever in
P or N, the
following message appears in the display:
When stationary apply footbrake while selecting gear.
When you a select a different gear (for example: R, D, etc.), the
message will disappear and the Auto-Check function is displayed.
If there is a malfunction, then the malfunction message will appear
about 15 seconds after the you start the vehicle. At the same time
you will hear a warning tone .•
Driver information messages
Driver information messages are shown in the instrument
cluster display in addition to the red and yellow symbols.
Fig. 17 Instrument
cluster: CHECK button
For example, if the transmission selector lever is not in the P posi­
tion when the engine is turned off, the following message appears:
Shift to P, otherwise vehicle can roll away. Doors do not lock if
lever is not in P.
The ignition key can only be removed with the selector in this posi­
tion. This and other messages are brought up if a function cannot
be carried out.
Driver messages and red symbols
If a red symbol appears in the display, a driver message can be
shown by pressing the [
CHECK) button.
For example, the symbol for a problem with engine oil pressure
"1::71
appears in the display . If you then press the [ CHECK) button, the
following driver message appears in the display:
Switch off engine and check oil level
The driver message in the display goes out after about 5 seconds.
