On Board Diagnostic
System (OBD)
Malfunction indicator lamp (MIL)
The malfunction indicator lamp (MIL) ¢4 in the
in strument cluster is part of the On Board Diag­
n ostic System (080 II).
The indicator light turns on when the ign ition is
switched on and turns off once the engine is
started and is running in idle at a stab le speed.
This indicates that the MIL is functioning correct­
l y .
Cockpit overview
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 cata lytic converter 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 Audi dealer or author­
ized Audi Service Facility.
The electronic speed limiter may be fau lty if the
indicator light turns on. For additional informa­
tion, see
Q page 23 .
The MIL may also turn on if the fuel filler cap is
not closed correctly
Q page 314.
On-Board Diagnostics
Fig. 19 Locat ion of Data Link Co nnector (D LC)
On-Boa rd Diagnostics monitors the components
of your 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 .
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 refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed
¢ page 314.
In order to make an accurate 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 diagnostic equip­
ment, push the plug into the Data Link
Connector .,.

A WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!

Opening and closin g
Opening and closing
Central locking
Description
You can lock and un lock the veh icle centrally . You
have the following options:
-Remote control key <=> page 36, or
-Sensors in the front door handles"
<=>page 36, or
-Lock cylinder on the driver's door<=> page 38,
or
-Interior central locking switch <=> page 3 7.
Tu rn sign als
The turn s ignals flash tw ice when you unlock the
vehicle and flash once when you lock the vehicle.
I f they do not f lash, then the ignition may still be
sw itched on or one of the doors , the luggage
compartment, or the hood may be open, for ex­
ample.
Autom atic locking (Auto Lock )
The Auto Lock funct ion 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 aga in if the ign ition key is
removed, the opening function in the centra l
lock ing switch is act ivated, or one of the door
handles is operated. The Auto Lock f unct ion can
be switched on and off in the Infotainment sys­
tem <=>
page 38.
In the event of a crash with a irbag deployment,
the doors will a lso automat ica lly unlock to allow
access to the vehicle.
Selective door unlocking
The doors and luggage compartment lid w ill lock
when they close. You can set in the Infotainment
system whether
only the driver's door or the en­
tire ve hicle should be unlocked when unlocking
<=> page 38.
Unintentionally locking yourse lf out
Only lock your vehicle when all of the doors and
the luggage compartment lid a re closed and the
34
remote control key is not in the vehicle. This
helps to prevent you from locking yourself out
accidenta lly.
The following conditions prevent yo u from lock­
ing you r remote control key in the vehicle:
-If the driver's door is open, the vehicle cannot
be locked by press ing the
Iii button on the re­
mote contro l key or touching the locking sen ­
sor* on a doo r.
-If the most recently used convenience key* is in
the luggage compartment, the luggage com­
partment lid automatically unlocks again after
closing it.
-If the convenience key* that was last used is de ­
tected inside the vehicle, then the vehicle will
not be ab le to lock from the outside.
A WARNING
-Always take the veh icle key with you when
leaving the vehicle, even for a short period
of t ime. This applies part icularly when chil­
dren remain in the vehicle . Otherwise the
children could start the eng ine or ope rate
electrical equipmen t such as power win­
dows.
- No one, especially ch ildren, should stay in
the vehicle when it is loc ked from the out­
side, because the windows can no longer be
opened from the
inside ¢ page 38. Locked
doors make it more difficu lt for emergency
workers to get into the vehicle, which puts
lives at risk.
(D Tips
-Do not leave va luables unattended in the ve­
hicle. A locked vehicle is not a safe!
-T he LED in the driver's door rail blinks 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.
