On-Board Diagnostic system (08D)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warning/ind icator light illuminates when the ignition is
switched on and goes out after the engine starts and the id le has
stabi lized. This indicates that the MIL is working proper ly .
If the light does 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 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
malfunctioning. For more information=>
page 23, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
=> page 267. •
On-Board Diagnostics
Fig. 17 location of
Data Link Connector
(DLC)
ai,,,

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
will 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 illuminates after a refueling,
stop the vehicle and make sure the fuel filler cap is properly closed
=> page 267.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBDl.
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 22, fig. 17.
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 299.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Indicator Lamp (MIU will illuminate. If this
occurs, contact the nearest authorized Audi dealer for assistance.
