On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) • in the instrument cluster
::::>
page 14, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
Th e warn ing/indicator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
Thi s ind icates 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 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 accelerat ions) and have the condition corrected .
Contact your authorized Audi dealer .
If the light i lluminates, 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 (only vehicles with gasoline engine)::::>

On-Board Diagnostics
Fig . 21 Location of
Data Link Connector
( DLC )
On-Board Diagnostics monitors the components of your emission
control system. Each monito red component in you r engine system
has been ass igned a code. I n case of a malfunct ion, the component
wi ll be ident ified and the fau lt 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 (only
vehicles with gasoline engine)::::>
page 294.
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 lo cated to the right of
the hood release
::::> fig. 21.
Your authorized Audi dealer or qualified workshop can interpret the
code and perform the necessary repair .•
Electronic speed limiter
Your vehicle may be factory equ ipped w ith tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your veh icle. 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 330.
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfunction Indicator Lamp (MIL)
0 will illuminate . If this
occurs, contact the nearest authorized Aud i dea ler for ass istance.

tion . This and other messages are brought up if a function cannot be
carried out.

-Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be the
cause of the malfunction.
If the O warning symbol (alternator malfunction) also lights up on
the instrument panel:::::,
page 34, then the fan belt may be damaged .
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the

Engine oil pressure malfunction 't:::f:
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 ~ 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! Oil pressure too low
Immediate actions
- Pull off the road.

Dipstick readings checks too low
- Top off oil to the proper level=> page 306 .
Make sure that the oil pressure warning symbol~
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
- If the oil pressure warning symbol ~ 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. •
