Volkswagen Golf Mk5 Tiguan 5N Windscreen Rain Sensor 1K0955559AF

Volkswagen Golf Mk5 Tiguan 5N Windscreen Rain Sensor is an original wiper system component designed for precise detection of precipitation on the windshield. Thanks to the factory Volkswagen design, the sensor works with the wiper control system, ensuring automatic response to changing weather conditions and improving driving comfort. It is a practical solution for drivers who expect stable wiper operation without the need for manual adjustment.

Function and application of the rain sensor

The rain sensor in Golf Mk5 and Tiguan 5N models is responsible for continuous measurement of the amount of water on the windshield surface and transmitting a signal to the wiper control module. Based on this data, the system selects the wiper operating frequency, which reduces the "dry wipe" effect and improves visibility in rain, drizzle, or during sudden downpours. This component is mounted in the inner zone of the windshield, near the rearview mirror, where it has optimal access to the wiper's working surface. As a result, it reacts to real conditions on the glass, rather than just general ambient humidity.

Compatibility and integration with the wiper system

The sensor in question has been designed as part of the wiper system in Volkswagen vehicles, which means full integration with the factory control and the vehicle's electrical installation. In practice, this translates into:

• proper cooperation with the wiper switch in automatic mode,
• consistency of operation with the comfort module and other body functions,
• stable operating parameters under typical operating conditions. Thanks to the original design, installation takes place in the location intended by the manufacturer, without the need for modifications to the installation or the use of additional adapters.

Characteristics of the used component

The presented rain sensor comes from dismantling and is offered as a used part. Such components are often chosen for wiper system maintenance when one wants to maintain the original manufacturer's specification while optimizing costs. A used component allows you to restore the automatic wiper function in a car where the factory sensor has been damaged or has stopped correctly detecting precipitation. Choosing an original, used sensor is particularly beneficial where compliance with factory software and the operating parameters of the entire system is important.

Practical benefits of installing a rain sensor

Using a functional rain sensor in a Golf Mk5 or Tiguan 5N translates into a number of practical advantages in daily use:

• Wiper automation – the system automatically selects the wiper blade movement frequency based on the intensity of precipitation.
• Improved safety – faster reaction to sudden precipitation increases road visibility.
• Driver comfort – no need to constantly switch wiper speeds during changing conditions.
• Reduced mechanism wear – reduction of unnecessary operating cycles during light drizzle. For users who want to maintain the full functionality of their Volkswagen's equipment, a functional rain sensor is an important part of the wiper system.
