On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) (4 i n
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the idle has stabilized .
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing, a malfunction may exist in the eng ine sys­
tem . If the light illuminates, the catalytic con­
verter could be damaged .
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed
limiter may also be malfunct ioning. For more
information
c:> page 31 , Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the
MIL light to illuminate
c:>page 217.
On-Board Diagnostics
Fig. 18 Locat io n of Data Link Con nector (D LC)
On-Board Diagnostics monitors the compo­
nents of your emission control system . Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, 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 fuel vapor recovery sys­
tem. If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed
c:> page 217.
In order to make an accurate diagnosis, the
stored data can on ly be displayed using spe­
c ial diagnostic equipment (generic scan tool
furOBD) .
~

In o rder to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC) . The DLC is located to the
right of the hood release ¢
fig. 18.
Your authorized A udi dealer or qualified work­
shop can interpret the code and perform the necessary repa ir.
A WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a coll is ion!
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). Thi s is may be less than

trol if the vehicle is operated at excessive

limiter. The electronic speed limiter prevents
your veh icle from going faster than the t ire
speed rat ing . For more informat ion
¢ page 246 .
If the engine control unit rece ives fa ulty vehi ­
cle roadspeed signa ls, the Ma lfunction Indica­
tor Light (MIL)

curs, contact the nearest authorized Audi
deale r for assistance.
A WARNING
