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

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
