The BMW 3 Series G20, introduced in 2019, boasts a wide range of advanced features, including an innovative wiper system. This article provides a detailed overview of the BMW 3 Series G20 wiper, from its design and operation to its maintenance and troubleshooting.

 Design and Operation

Aerodynamic Design: The BMW 3 Series G20 wiper features an aerodynamic design that minimizes wind noise and enhances efficiency. The streamlined shape of the wiper blades ensures optimal contact with the windshield, even at high speeds.

Sensor-Based Control: The wiper is equipped with rain sensors that automatically detect moisture on the windshield. These sensors activate the wiper at the appropriate speed and interval, ensuring clear visibility in all weather conditions.

Intermittent Function: In addition to continuous wiping, the wiper offers an intermittent function that provides periodic wiping cycles at adjustable intervals. This is ideal for light rain or mist.

Variable Wiping Speed: The wiper system allows the user to select the wiping speed from a range of options, including slow, moderate, and fast. The appropriate speed can be chosen based on the intensity of the rain.

 Maintenance and Troubleshooting

Wiper Blade Replacement: Over time, the wiper blades will wear out and need to be replaced. The process of replacing the blades is relatively simple and can be done by most drivers.

Wiper Fluid: The wiper system relies on washer fluid to remove dirt and debris from the windshield. It is important to keep the fluid reservoir filled and to use a high-quality washer fluid that is compatible with the vehicle.

Common Issues: Some common issues that may affect the BMW 3 Series G20 wiper include:

 Streaking: This can be caused by worn wiper blades, dirty windshield, or contaminated washer fluid.
 Skipping: This occurs when the wiper blades do not make full contact with the windshield. The problem could be caused by a worn linkage or a blocked nozzle.
 Noise: Excessive noise during wiping can be caused by worn or damaged wiper blades or a loose linkage.

 Troubleshooting Steps

Streaking:

 Replace the wiper blades.
 Clean the windshield with a glass cleaner.
 Use a high-quality washer fluid.

Skipping:

 Check the linkage for obstructions or damage.
 Clean the wiper nozzles to ensure they are not blocked.

Noise:

 Inspect the wiper blades for wear or damage.
