On-Board Diagnostic
system (OBD)
System indicator light (MIL)
The system indicator ligh t (M IL) ¢.§ in the in ­
str ument cl uster is part of the On Board Diag­
nostic System (OBD II).
T he warni ng/i ndicator light t urns on when the
ignition is sw itched on and t urns off once the
engine is sta rted and is runn ing in id le at a
stab le speed. This indicates that the MIL is
funct ioning correct ly.
If the light does not turn off after sta rting
the engine
or turns on while driving, t his may
indicate there is a ma lfunction in the engine.
If the indicator turns on, the cata lytic convert­
er may be damaged .
Drive
with reduced engine performance
(avoid high speeds for extended periods of
time and/or fast acceleration) and have the
malfunction corrected. See an authorized Audi
dealer or author ized Audi Service Facility.
The indicator may turn on if the electronic
speed limiter is faulty. For addit ional informa­
tion, refer to Q
page 30, Electronic speed
limiter* .
The MIL may also turn on if the fuel filler cap
is not closed cor rectly

On-Board Diagnostics
Fig. 15 Lo cat ion of D ata Link Connec tor (D LC)
On-Board Diagnostics monitors the compo­
nents of your emission con trol system. Each
monitored component in your engine system
has been assigned a code . In case of a mal­
function, the component will be ident ified
and the fau lt stored as a code in the control
module memory .
The MIL light may also illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem.
If the lig ht illuminates after a refuelling ,
stop the veh icle and ma ke sure the fuel filler
cap is proper ly closed
<> page 212.
I n o rder to make an accurate d iagnosis, the
stored data can only be displayed using spe­
cia l diagnostic eq uipment (gener ic s can tool
for OBD).
I n o rder to connect the special diagnostic
equipment, push the p lug i nto the Data Link
Connector (DLC). The DLC is located to the

form the necessary repa ir .
A WARNING
Do not use the diagnostic con nector for
personal use. Incorrect usage can ca use
ma lf u nctions, which can increase the risk
of a coll ision!

Electronic speed limiter*
Applies to vehicles: with electronic speed limiter
Your vehicle may be factory eq uipped w ith
t ir es that are rated fo r a max imum speed of
130 mph (210 km/h) . This is less than the
maximum speed of your vehicle. To reduce the
risk of sudden tire fa ilure and loss of contro l if
the vehicle is operated at excessive speeds,
your vehicle a lso has an electronic speed limit­
er . The elec tronic speed limi ter prevents your
vehicle from going faster than the tire speed rating . For more information ¢
page 248.
If the engine control unit receives faulty veh i­
cle road speed signa ls, the Malfunction Ind i­
cator Lamp (M IL)
¢..fi will illuminate . If this
occurs, contact the nea rest authorized A udi
dealer for assistance .
A WARNING
Always observe the posted speed lim its
a nd adjust your speed to suit prevai ling
road, traffic and weather cond itions. Never
d rive your vehicle faster than the maxi­
mum speed rating of the tires installed. -
