On-Board Diagnostic
System (OBD)
Malfunction indicator lamp (MIL)
The malfunction indicator lamp (MIL) ¢.j in the
instrument cluster is part of the On-Board Diag­
nostic System (OBD II).
The warning/indicator light turns on when the ig­ nition is switched on and turns off once the en­
gine is started and is running in idle at a stab le
speed. This indicates that the MIL is functioning
correct ly.
If the light does not turn off after starting the
engine
or turns on while driving, this may indi­
cate there is a malfunction in the engine.
If the
indicator turns on, the catalytic converte r may be
damaged .
Drive
with reduced engine performance (avoid
high speeds for extended periods of time and/or
fast acceleration) and have the malfunction cor­
rected. See an authorized Aud i dealer or autho r­
ized Audi Service Facility.
The MIL may also turn on if the fuel filler cap i s
not cl osed correctly

On-Board Diagnostics
Fig. 5 Location o f Data Li nk Con necto r (OLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction , the com­
ponent will be identified and the fault sto red 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 system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed (only vehicles with gasoline engine)
r::'.>page 153 .
In order to make an acc urat e diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for 080).
In order to connect the special d iagnost ic equip­
ment, push the p lug into the Data Lin k Connector
(DLC). The DLC is located to the right of the hood
release ¢

Your authorized Aud i dea ler or qualified work­
shop can interpret the code and perform the nec­
essary repair.
_& WARNING ~
Do not use the diagnostic connector for per-
sona l use. Incorrect usage can cause malfunc­

Central locking
Description
You can lock and unlock the vehicle centrally . You
have the following options:
- Remote control key <=>
page 24,
-Sensors in the door handles" <=> page 24,
-Inner central locking switch <=>page 25, or
- Lock cylinder on the driver's door<=>
page 26.
Turn signals
The turn s ignals flash twice when you unlock the
veh icle and flash once when you lock the vehicle.
If they do not flash, then the ignition may still be
sw itched on, or one of the doors or the luggage
compa rtment lid may be open, fo r example.
Automatic locking (Auto Lock)
The Auto Lock function locks all doors and the
luggage compartment lid once the speed has ex ­
ceeded approx imately 9 mph (15 km/h).
The vehicle will unlock again if the ignition key* is
removed, the opening function from the central
locking switch is activated, or one of the door
handles is operated .
In the event of a crash with airbag deployment,
the doors will also automatically unlock to allow
access to the vehicle.
Selective door unlocking
The doors and luggage compartment lid wi ll lock
when they close. You can set in the Infotainment
system if
only the driver's door or the entire vehi­
cle should unlock when unlocking<=>
page 26,
Setting the central locking system .
Unintentionally locking yourself out
Only lock your vehicle when all of the doors and
the luggage compartment lid are closed and the
remote control key is not in the vehicle. This
helps to prevent you from locking yourself out
accidentally .
The fo llow ing conditions prevent you from lock­
ing your remote control key in the vehicle :
22
-If the driver's door is open, the vehicle cannot
be locked by pressing the
!'.II button on the re­
mote contro l key or by touching the locking
sensor* on a door .
- If the most recently used convenience key* is in
the luggage compartment, the luggage com­
partment lid automatically unlocks again after
closing it<=>
page 2 7. The emergency flashers
blink four t imes.
- If the convenience key* that was last used is de­
tected inside the veh icle, then the vehicle will
not be able to lock from the outside .
A WARNING
-Always take the key with you when leaving
your vehicle, even if for a short pe riod of
time. This applies particularly when children
remain in the vehicle. Otherwise, children
could start the engine or operate electrical
equipment (such as power windows), which increases the risk of an accident.
- No one, especially children, should stay in
the vehicle when it is locked from the out­
side, because the windows can no longer be
opened from the inside <=>
page 2 7. Locked
doors make it more difficult for emergency
workers to get into the vehicle, which puts
lives at r isk .
A WARNING
Appl ies to: ve hicles with ignition loc k
Do not remove the key from the ignition lock
until the vehicle has come to a complete stop.
Otherwise, the steering lock could engage
suddenly and increase the risk of an accident.
(D Tips
-Do not leave va luables unattended in the ve­
hicle. A loc ked vehicle is not a safe!
- The LED in the dr iver's door rail b links when
you lock the vehicle. If the LED lights up for
approximate ly 30 seconds after locking,
there is a malfunction in the centra l locking
system . Have the problem corrected by an
authorized Audi dealer or authorized Aud i
Service Facility.
