the vehicle is at a standstill, or if you are driving at a very low speed, the temperature shown in the display might be slightly higher than
the actua l outs ide temperature. This is caused by the heat be ing
radiated from the engine.

On-Board Diagnosti cs
Fig . 15 Location of
Data Link Connector
(DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each controlled 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 .
Th e MIL lamp may also illuminate if there is a leak in the on -board
fuel vapor recovery system. If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed
=> page 246.
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 engine hood release lever=> 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 279, "New tires and
replacing tires and wheels".
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfunction Indicator Lamp (Mill 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. •
