ly.
If the light does not go out afte r the e ngine

i ng, a mal function may exist in the engine sys ­
tem . If t he light illum inates, t he catalytic con-

Instruments and warning/indicator lights 2 7
Continue driving with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erat ions) and have the condition corrected.
Contact your author iz ed Audi dealer.
If the light ill uminates, the electronic speed
limiter may also be ma lfunctioning . For more
information ¢

limiter .
An improperly closed fuel fi ller cap may also
cause the MIL light to ill uminate ¢

On-Board Diagnostics
Fig. 12 Loca tion of Data Li nk Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of yo ur emission control system. Each
mon itored component in your engine system
has been assigned a code. In case of a ma l­
function, the component will be identified and the fault stored as a code in the contro l
module memory.
The MIL light may a lso illuminate if there is a
l eak in the on-board fue l vapor recovery sys­
tem. If the light illuminates after a ref uelling,
stop the veh icle and make sure the fue l filler
cap is properly closed ¢
page 217.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (gener ic scan tool
for OBD).
In order to connect the special diagnostic
eq uipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the right of the hood release¢
fig. 12.
Your authorized Audi dea ler or a qualified
service station can interpret the code and per­
form the necessary repair.
A WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, wh ich can increase the risk
of a collision!
Electronic speed limiter
-
Your vehicle may be factory equipped w ith
t ir es that are rated fo r 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 fai lure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle a lso has an e lectronic speed limit­
er . The e lectronic speed limiter prevents your
vehicle from going faster than the tire speed rating . For more information ¢
page 246.
If the engine contro l unit receives faulty vehi­
cle road speed signa ls, the Ma lfunction Indi·
cator Lamp (MIL)
fllllij w ill illuminate. If this
occurs, contact the nearest authorized Audi
dealer for assistance .
A 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 maxi­
mum speed rating of the tires installed.
