On Board
Diagnostic
System
(OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL)
¢..ift
in
the
instrument cluster is part of the On-Board Diag-
nostic (OBD II) system
.
The
warning/indicator
light
illuminates
when the
ignition is switched on and goes out after the en-
gine starts and the
idle has
stabilized. This indi-
cates that the MIL is working properly
.
If the light does not go
out
after the engine is
started, or illuminates while you are driving, a
malfunction may exist in the engine system.
If
the light
illuminates,
the catalytic converter
could be damaged.
Continue driving
with reduced power
(avoiding
sustained high speeds and/or rapid accelera-
tions) and have the condition corrected. Contact
your authorized Audi dealer.
If the light illuminates, the electronic speed lim-
iter may also be malfunctioning.

The MIL light may also illuminate if there
is
a
