Data Link Co nnector
( DL Cl
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
f ue l vapor recovery system. If the light i lluminates after a refuelling,
stop the vehicle and make sure the fuel filler cap is properly closed
=:>
page 216.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan too l for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLCl. The DLC is located to the right of
the hood release =:> fig . 14.
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 vehic le from going faster than the
tire speed rating. For more in formation=:>
page 249.
If the vehicle approaches the tire speed rating, the engine control
unit will turn off the fue l injectors. You will notice an immediate loss
of engine power and a drop in road speed .
If the engine control unit receives faulty vehicle roadspeed signals,
the Ma lfunction Indicator Light (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. •
