On-Board Diagnostic system (OBD)
On-Board Diagnostics
Fig. 10 Locat ion 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 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 light may also illuminate if there is a leak in the on -board
fuel vapor recovery system. If the light ill uminates after a refuelling,
stop the vehicle and make sure the fuel fi ller cap is properly closed
~ page 213.
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 hood release =>
page 24, fig. 10.
Your authorized Audi dealer or a qualified service station can inter ­
pret the code and perform the necessary repair. •
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=>
page 15, fig. 5 is part of the On -Board Diagnostic (OBD II) system.
The warning/indicator light illuminates 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 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 25, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate =>
page 213. •
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-
Controls and equip ­
ment
Driver information system
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information =>
page 246.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Indicator Light (MIU•"" will illuminate. 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. •
