Service interval display
The service interval display reminds you when your next
service is due.
Fi g. 14 D isplay:
Se rvice i nterval displ ay
The date for service is calculated automa tically. Based on the
average distance driven in previous months, a monthly driving
distance is calculated. As soon as the distance remaining to the next
service drops below the distance driven monthly, the service
reminder is initiated. The maximum period from one service to the
next is one year.
S erv ice reminder
30 days before the next service is due, a service reminder appears
in the display when you turn on the
i gnition => fig. 14.

0 Note
I f you disconnect the battery terminals, no calculations can be
made for the service interval display during this time and no service
reminder will appear. Remember that observing the proper service
intervals is vita lly important to extending the life of you r 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 (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 16, fig. 7 is part of the On -Board Diagnostic (OBD II) system.
The 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 d oes not go out after the engine is started, or illuminates
while you are driving, a ma lfunction may exist in the engine system.
If the light starts flashing, the catalytic converter cou ld be damaged.
Continue driving
w ith redu ced po wer (avoiding sustained high
speeds and/or rapid accelerat ions) and have the condition
corrected. Contact your authorized Audi dea ler.

On-Board Diagnost ics mon itors the components of your emission
control system. Each monitored component in your engine 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 memo ry.
The MIL light may a lso illuminate if there is a leak in the on-board
fue l vapor recovery system . If the light ill uminates after a refue lling,
stop the vehicle and make sure the fue l fi ller cap is proper ly closed
=> page 303.
In order to make an accurate diagnosis, the stored data can o nly be
displayed using special diagnostic equipment (generic scan tool for
OBD).
In order to connect the spec ial diagnostic equipment, push the p lug
into the Data Link Connector (DLC). The DLC is located to the right of
the hood re lease
=> fig. 15. Your authorized Audi dealer or a qua
lified service station can inter­
pret the code and perform the necessary repair. •
Electronic speed limiter
Your vehicle may be factory equipped with tires t hat 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 t ire
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limiter. The e lec­
tronic speed limiter prevents your vehic le from going faster than the
tire speed rating . For more
information => page 336.
lf the veh ic le approaches the tire speed rating, the engine control
unit wi ll turn off the fue l injectors. You will notice an immediate loss
of engine power and a drop in road speed.
If the engine contro l unit receives faulty vehic le road speed signals,
the Ma lfunction Indicator Lamp (MIU

occurs, contact the nearest authorized Audi dealer for ass istance.
