Logic of naming sensors in VW-group is simple it contains "G" (german "Geber") + sensor number. The sensor number is unique. Here you can find fitting location, connectors and pins description, some information about sensors signals.

To our mind, sensors information is reference, so there is only simple search by sensor number.

Ultra-sonic interior monitor


General notes

The ultra-sonic interior monitor is offered only in conjunction with the anti-theft alarm system. The additional ultra-sonic interior monitoring enhances the security offered by the anti-theft alarm system.

The interior monitor triggers the anti-theft alarm when an illicit attempt is made to intrude into the vehicle by way of the side windows.



The ultra-sonic interior monitor comprises:

* Ultra-sonic sensor, anti-theft alarm -G209

* Interior monitor switch -E183


The sensor module behind the courtesy lamp monitors the side windows and is connected to the central locking control unit. If the monitoring signal deviates, the central locking control unit triggers the alarm.

The central locking control unit operates the indicator lamps next to the door locking buttons.

With the interior monitor switch the interior monitoring can be disabled manually for a specific locking operation, such as when a dog is left in the vehicle.
