On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢• in the
instrument cluster
c:::> page 14, fig. 8 is part of the
On-Board Diagnostic (OBD II) system.
The warning/indicator light i lluminates 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 acce lerations)
and have the condition corrected. Contact your
authorized Audi dealer.
I f the light illuminates, the electronic speed lim
iter may also be malfunctioning. For more infor
mation
c::> page 26, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate (only vehicles
with gasoline engine)
c:::> page 216.
On-Board Diagnostics
F ig . 21 Locat ion of Data link Connector (DLC)
On-Board Diagnostics monitors the components
of yo ur emission control system. Each monitored
component in your engine system has been as
signed a code . In case of a malfunction, the com
ponent will be identified and the fault stored as a
code in the control module memory.
26
The MIL light may also illuminate if there is a
l eak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop
erly closed (only vehicles with gasoline engine)
c::> page 216.
In order to make an accurate diagnosis, the stor
ed data can only be displayed using specia l diag
nostic equipment (generic scan tool for OBD).
In order to connect the specia l diagnostic equip
ment, push the plug into the Data Link Connector
(DLC) . The DLC is located to the right of the hood
release
c::> fig. 21.
Your authorized Audi dealer or qualified work shop can interpret the code and perform the nec
essary repair .
A WARNING
Do not use the diagnostic connector for per
sonal use. Incorrect usage can cause malfunc
tions, which can increase the r isk of a coll i
sion!
Electronic speed limiter
Your vehicle may be factory equ ipped with tires
that are rated for a maximum speed of 130 mph
(210 km/h) . Th is is less than the max imum speed
of your veh icle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is ope rat
ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
limiter prevents your vehicle from going faster
than the tire speed rating. For more information
c::> page 242.
If the engine contro l unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL) ¢•will illuminate. If this occurs,
contact the nearest authorized Audi dealer for as
sistance.
