On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL )
The Ma lfunction Indicator Lamp ( MIL ) ¢'4 in
the instr ument cluster is part of the On-Board
Diagnostic (OBD II) system .
T he wa rni ng/indicator light ill uminates when
the ignit io n is switched on and goes out after
the engine sta rts and the id le has stab ilized.
This indicates that the MIL is working proper­
ly .
If the light does not go out afte r th e en gine
is started, or illuminates while you are dr iv­
ing, a mal function may exist in the engine sys ­
tem.
If the lig ht illum inates, the catalyt ic con­
verter could be damaged .
Contin ue driving
with reduced power (avoid­
ing s ustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact your aut horized Audi dea ler.
If the light illuminates, the e lectronic speed
limiter may also be malfunct ioning . For more
information
c> page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c> page 219.
On-Board Diagnostics
Fig. 1 6 Location o f Data Li nk Co nnector (D LC)
On-Board Diagnostics monitors the com po­
nents of your emission cont ro l system. Each
monitored component in your engine system
Iii>-

30 Instruments and warning /indicator lights
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
leak in the on-board fue l vapor recovery sys­
tem .
If the light illuminates after a refue lling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢
page 219.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBD) .
In order to connect the special diagnostic
equipment, push the plug into the Data L ink
Connector (DLC). The DLC is located to the
right of the hood release¢
fig. 16.
Your authorized Audi dealer 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, which can increase the risk
of a coll ision!
Electronic speed limiter
-
Your veh icle 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 you r vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your veh icle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from go ing faster than the tire speed
rating. For more informat ion ¢
page 260 .
If the engine control unit receives faulty vehi­
cle road speed s ignals, the Malfunction Indi­
cator Lamp (MIU
¢'4 will illuminate. If this
occurs, contact the nearest authorized Aud i
dealer for assistance. S models
Your
vehicle's top speed is elect ron icall y limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty veh i­
cle roadspeed signals, the Malfunction Indica­
tor Lam p (MIL)
¢'4 will illuminate . If this oc­
curs, 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 cond itions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed .
