On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) II! 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 o ut 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 ma lfunction 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
erations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed
limiter may also be malfunctioning. For more information

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

On-Board Diagnostics
Fig. 16 Locat ion of Data L ink Con nector (DLC)
On-Board D iagnost ics monitors the compo­
nents of your em iss ion 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.
T he MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem.
If the light illum inates after a refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed

equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the
right of the hood release
