On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL }
The Malfunction Indicator Lamp (MIL)¢• in
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 engine 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
erat ions) and have the condition corrected .
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more

limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostics
Fig. 15 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your em iss ion contro l 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 230.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBO) .
In order to connect the specia l diagnostic
equipment, push the plug into the Data Link
Connector (OLC). The DLC is located to the

vent passengers (children, for example)
from accidentally being locked in the ve­
hicle should they accidentally press the
power locking switch in the doors.
- Do not leave children inside the vehicle
unsupervised. In an emergency it would
be impossible to open the doors from
the outside without the key.

cannot provide the security of a safe.
- If the LED in the upper edge of the driv­
er's door panel comes on for about 30
seconds after the vehicle is locked, there
is a malfunction in the power locking or
the anti-theft warning system. Have the malfunction corrected by an authorized
