On-Board Diagnostic system (OBD)
On-Board Diagnostics
Fig. 9 Location of
Data Link Connector
(DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each controlled component in your eng ine 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
memory .
The MIL lamp may also illuminate if there is a leak in the on-board
fuel vapor recovery system.
If the Light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed~
page 222.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBD).
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 engine hood release lever~ fig. 9. Your authorized
Audi dealer or a qualified service station can inter­
pret the code and perform the necessary repair.•
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models )
The Malfunction Indicator Lamp (MIL) in the instrument cluster
~ page 11, fig. 5 is part of the On-Board Diagnostic (OBD II) system.
T he 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 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 accelerations) and have the condition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed limiter may also be
ma lfunction ing. For more information~
page 20, "E lectronic speed
limiter" .
An improperly closed fuel filler cap may also cause the MIL light to
illuminate~
page 222 . •
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 less than the
maximum speed of your veh icle . 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 limiter . The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information~
page 259, "Speed rating
(letter code)".
~

If the engine control unit receives faulty vehicle roadspeed signals,
t he Mal func tion In dica tor Ligh t (M IL)
t::: will illuminate. If th is
occu rs, contact the nearest authorized Audi dea ler fo r ass istance .
& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road, traffic and weather conditions. Never drive
your vehicl e faster than the m aximum speed rating of the tires
in stalled .•
