the vehicle and turn off the engine . The water pump is not working
- this can cause engine damage. •
Electronic stabilization program (ESP) This warning/indicat or light monitors the electr onic stabi ­
lization program .
The warning/indicator light has the following functions:
• It blinks while you are driving when the ESP is working .
• It illuminates when you switch on the ignition for approximate ly
2 seconds as a function check .
• It illuminates when there is a malfunction in the ESP. The
message
E S P f ault ! Se e owner 's manual also appears in the instru ­
ment cluster display and a warning tone sounds .
• It illuminates continuously when the ESP is switched off .
• It illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS system.
If the battery terminals were disconnected and re-connected , the
vehic le was jump started or the batte ry is very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light illuminates . The warning/indicator light
goes out as soon as the learning process is complete.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (Mill in the instrument cluster
=>
page 16, 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 author ized Audi dealer .
Vehicle care I I irechnical data

Driver information display
If the light illuminates, the electronic speed limiter may also be
malfunctioning. For more information~
page 28, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate

On-Board Diagnostics
Fig. 15 Location of
Data Link Connector
(DLCl
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 305.
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 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 338.
If the vehicle approaches the tire speed rating, the engine control
unit will turn off the fuel injectors. You will notice an immediate loss
of engine power and a drop in road speed.
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.
& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road, traffic and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires installed. •
