With the ignition switched on, the warning il­
luminates when at least
one door or the hood
or the rear lid is not closed . The symbol also
shows you
which door(s) or lid is not closed .

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL }
The Malfunction Indicator Lamp (MIL)¢• in
the instrument cluster 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 proper ­
ly .
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing, a malfunction may exist in the engine sys­
tem .
If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erat ions) 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
c:> page 29, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c:> page 230.
On-Board Diagnostics
Fig. 15 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your em iss ion contro l system . Each
monitored component in your engine system
has been assigned a code . In case of a mal­
function, 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 sys­
tem .
If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler cap is properly closed
c:> page 230.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBO) .
In order to connect the specia l diagnostic
equipment, push the plug into the Data Link
Connector (OLC). The DLC is located to the
right of the hood release
c:> fig. 15.
Your authorized Aud i dealer or a qualified
service station can interpret the code and per­
form the necessary repair.
A WARNING ""-=--
Do not use the d iagnost ic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!

Electronic speed limiter
Your vehicle may be factory equipped with
tires that are rated for a maxim um 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 veh icle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating. For more informat ion
c::> page 260 .
If the engine control unit receives faulty vehi­
cle road speed s ignals, the Malfunction Indi­
cator Lamp (MIU
¢..ifi will illuminate. If th is
occurs, contact the nearest authorized Aud i
dealer for assistance.

Your veh icle's top speed is electronically limit­
ed to 155 mph (250 km/h) .

cle roadspeed signals, the Malfunction Indica­
tor Lamp (MIU ¢.jj will illuminate. If th is oc­
curs, contact the nearest authorized Audi
dealer for assistance .
A WARNING
