Function and Application of the BMW Windshield Condensation Sensor

The BMW windshield condensation sensor works with the air conditioning and ventilation control modules, monitoring conditions around the front windshield. Based on the signal from the sensor, the control unit can:

• increase the fan speed directed at the windshield,
• modify the air distribution within the cabin,
• appropriately adjust the air drying parameters.

This action reduces the risk of sudden visibility impairment, which is important for both safety and driving comfort in BMW models of the E60, E63, E65, E87, and E90 series.

Construction and Integration with Vehicle Electronics

The windshield condensation sensor is an electronic component designed to operate within the BMW control network, under the Switches, Control Elements, and Ignition Switches category. It is characterized by:

• a compact design that facilitates installation near the windshield,
• a dedicated connector for integration with the electrical wiring harness,
• compatibility with factory air conditioning control modules.

This ensures an organized installation process, and once correctly connected, the sensor is recognized by the vehicle's system without requiring any modifications to the wiring.

Benefits of Using an Original Condensation Sensor

Choosing an original BMW part from this group ensures consistent operation with the vehicle's other electronic systems. Key benefits include:

• stable cooperation with the factory control unit software,
• accurate humidity and temperature measurement characteristics in the windshield area,
• maintenance of the air conditioning system's intended responses as designed by the manufacturer.

A properly selected sensor reduces the need for additional diagnostics and minimizes the risk of errors related to incorrect readings of conditions at the windshield.

Condition, Selection, and Installation of the Sensor

The offered sensor is a used part, allowing for an economical replacement while maintaining compliance with BMW's factory specifications. Before installation, it is advisable to consider:

• compatibility with the vehicle's generation (E60, E63, E65, E87, E90),
• the type of air conditioning system installed in the specific vehicle,
• correct placement of the sensor in the location designated by the manufacturer.

Professional installation and potential adaptation within the vehicle's diagnostic system help to fully utilize the sensor's functionality and restore proper automatic defogging operation.
