On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU -in the instrument cluster
=> page 17, fig. 7 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 30, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
=> page 293. •

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 refuelling,
stop the vehicle and make sure the fuel filler cap is properly closed
=>
page 293.
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=> fig. 16.
Your authorized Audi dealer or a qualified service station can inter ­

Engine oil pressure malfunction ~
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low -oil -pres ­
sure indication is likely to inflict severe damage to the
engine.
If the "l=7': symbol appears in the display and blinks, the oil
pressure is too low. An additional driver message can also
be displayed by pressing the [
CHECK] button:
Switch off engine and check oil level
Immediate actions
- Pull off the road .
- Stop the vehicle.
- Turn off the engine.
-Check the engine oil level with the dipstick:::::> page 301.
Dipstick readings checks too low
- Top off oil to the proper level :::::> page 302.
-Make sure that the oil pressure warning symbol "l=7':
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
-If the oil pressure warning symbol "l=7': starts flashing
again even though the engine oil level checks OK on the
dipstick,
do not continue driving and do not let the
engine run in idle.
Instead, contact your authorized Audi
dealer for assistance.
[ i ] Tips
• The engine oil pressure symbol ~ is not an indicator for a low
engine oil level . Do not rely on it. Instead , check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip .
• The yellow oil level warning indication ... requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning
~ starts to flash before you respond to the low oil
level warning
= . By then, your engine may already have suffered
serious damage. •

Speed warning system
Overview
The speed warning system helps you to keep your driv ing
speed below a set speed limit.
The speed warning system warns the driver if he exceeds a previ ­
ously stored maximum speed . A warn ing tone wi ll sound as soon as
the vehicle speed exceeds the set speed by about 6 miles per hour
(10 k m/h). At the same time, a warning symbol appears in the
display.
The speed warning system has
t w o w arning thre sh o ld s that func ­
tion independent ly of each other and that have somewhat diffe rent
purposes:
S pee d war ning 1
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect until you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol
8 (USA mode ls)/ 8 (Canada models) in
the warning 1 display appears when you exceed the maximum
speed. It goes out when the speed falls below the stored maximum
speed.
The speed war ning symbol wi ll also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is deleted.
Setting speed warning 1
=> page 39 .
S pee d w arning 2
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a general maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
The speed warning 2 symbo l,
6 (USA models)/ 8, (Canada models)
appears in the display when you exceed the stored speed limit.
Un like warning 1, i t wi ll not go out unti l the vehic le speed drops
below the stored speed limit.
Setting speed warning 2
=> page 39.
[ i ] Tip s
Even though your vehicle is equipped with a speed warning system,
you shou ld still watch the speedometer to make sure you are not
driving faster than the speed limit. •
