On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) in the instrument cluster
~ page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warn ing/ind icator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicat es 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 co nverter 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 275. •
On-Board Diagnostics

m en t
Fig . 15 Locat ion of
Data Link Connector ( DLC )
Vehicle OP-eration
Driver information display
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 fue l
vapor recovery system. If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed
~ page 275 .
In order to make an accurate diagnosis, the stored data can only be
displayed using specia l diagnostic equipment (generic scan too l 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~ fig . 15.
Your authorized Audi dealer or a qualified service station can inter­
pret 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 307.
If the engine con trol unit receives faulty vehicle roadspeed signals,
the Malfunction Indicator Lamp (MIL) will illuminate. If this
occurs, contact the nearest authorized Audi dealer for ass istance . .,.
