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.

The ultrasonic interior monitoring system is
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.
