Remote transmitter, coding
Two remote transmitters are supplied with the
vehicle. If further transmitters are required, they
must be coded to interact properly with the
central locking control module.
This procedure must be performed after
changing the batteries in keys with remote
control function, or if the scan tool displays DTCs
of 00955 to 00958
Remote transmitter coding procedure
- Switch ignition on (using separate key).
- Check how many transmitters have already
been coded in measuring value block 003

Display field 2 indicates how many remote transmitters have been coded
and in which memory positions (in the example given, 1 transmitter in
position 1).
- Lock vehicle from outside using key to be coded via driver-side door
lock.
- Press "unlock" button within 5 seconds often enough to reach next
memory position (in example given, twice).

the anti-theft system horn.
- Wait 5 seconds.

- Now press "unlock" button one more time
(vehicle unlocks).
- Switch ignition off and remove ignition key.
- Check function of new transmitter.
- Check display field 2 in measuring value block
003. It should now display another "1" (in
example given: 1100).
Note:
Be sure that new transmitters are always coded
into free memory positions. If occupied positions
(distinguishable by a "1") are used, the
transmitter previously coded to this position will
no longer work.
Existing remote transmitter recoding
procedure
This procedure must be performed after
changing the batteries in keys with remote
control function, or if the scan tool displays DTCs
of 00955 to 00958
- Press any button on transmitter.
If vehicle does not respond by locking or
Central locking On Board Diagnostic (OBD)
- Lock and unlock vehicle within 30 seconds using
driver-side lock.
- Now check function of recoded remote
transmitter.
Clearing memory positions
Note:
It is possible to clear all memory positions, e.g. if
a customer loses a remote transmitter. Proceed
as follows:
Central locking On Board Diagnostic (OBD)
- Switch ignition on using key.
- Then mechanically lock central locking from
outside vehicle using key.
- Activate remote transmitter "unlock" button on
key five times at one second intervals. A short
horn signal will sound each time.
- Then, after 6 seconds, press remote transmitter
"unlock" button to confirm this clearing
procedure one more time.
Central locking should no longer unlock itself via
remote transmitter.
- Switch ignition off.
Up to four transmitters can now be coded again.
Ultrasonic interior monitoring On Board Diagnostic (OBD)
Ultrasonic interior monitoring
On Board Diagnostic (OBD)
General Information
The ultrasonic interior monitoring system is only
offered in conjunction with the anti-theft system.
The security provided by the anti-theft system is
enhanced through addition of the ultrasonic
interior monitoring option.
Interior monitoring activates the anti-theft alarm
when unauthorized attempts are made to enter
the vehicle through the side windows.
Function
The ultrasonic interior monitoring system
consists of:
Control module for ultra-sound sensors -
J347-
Ultra-sound sensor, left for anti-theft warning
system -G170-
Ultra-sound sensor, right for anti-theft warning
system -G171-
Ultrasonic interior monitoring On Board Diagnostic (OBD)
(only for Avant)
Sensor for broken window glass rear right -
G184- (only for Avant)
Switch for passenger compartment monitoring -
E183-
Ultrasonic interior monitoring On Board Diagnostic (OBD)
The ultra-sound sensors in the right and left
upper B-pillar trims monitor the side windows and
send the monitoring signal to the control module
for ultra-sound sensors.
If the monitoring signal deviates from the norm,
the control module for interior monitoring
activates the alarm via the control module for the
anti-theft system.
In addition to the contact switches in the lock
units, glass break sensors in side windows as
well as the conductor loop in rear window, (only
for Avant), serve for securing the exterior of the
vehicle.
The control module for interior monitoring
activates the warning lamps next to the door
locking buttons. These warning lamps provide
further information regarding the interior
monitoring system.
Repair Manual, Electrical Equipment
Interior monitoring can be manually shut off for
the duration of a door closing via the switch for
interior monitoring.
Owner's Manual
Ultrasonic interior monitoring On Board Diagnostic (OBD)
capable of extensive On Board Diagnostic
(OBD). If malfunctions in component parts
develop, DTCs are stored in the DTC memory of
the control module. Malfunctions can then be
identified using the VAG1551 or VAG1552 scan
tools.
