Purpose and function in the vehicle

The motor operates in the rear window area, responsible for the smooth movement of the wiper arm on the horizontal axis. Thanks to properly selected gear ratios and operating characteristics, the drive maintains a constant speed and the correct range of motion, which reduces blind spots on the glass. The rear mounting position allows for a direct connection to the wiper mechanism, without the need for additional intermediate components.

Construction and performance parameters

The component belongs to the Wiper motors and linkages group, which means a design adapted for operation in variable weather conditions and frequent activation cycles. The motor housing is designed for installation in the tailgate area, where vibrations, temperature changes, and humidity occur. The electric drive used works with the factory Audi installation, ensuring correct communication with the switches and wiper controls.

Thanks to a properly selected torque, the motor maintains stable arm operation even under higher resistance, e.g., during snowfall or the accumulation of debris on the glass. This translates into uniform surface cleaning and reduced arm vibration.

Benefits of use in an Audi

Selecting the right rear wiper motor has a direct impact on driving comfort and safety. With this model, the user gains:

• compatibility with the factory Audi wiper system,
• stable operation in both continuous and intermittent modes,
• correct arm positioning after the cycle is completed,
• consistency with the vehicle's original electrical installation.

As a used component, the motor allows for an economical repair of the wiper system while maintaining functionality close to factory standards. This solution is particularly beneficial for the comprehensive maintenance of older Audi A3, A4, or A6 models, where a reasonable balance between cost and component efficiency is important.

Selection, installation, and vehicle integration

Before installation, it is worth verifying the compatibility of the motor with the specific body version and vehicle year, using OEM markings and available interchangeable numbers in the technical specification. This facilitates matching the existing mount in the tailgate and the wiper arm. A correctly selected component allows for installation without structural modifications, using factory mounting points and electrical connectors.

During installation, it is important to maintain the correct resting position of the arm so that the wiper does not hit the seals or leave an uncleared field of vision after the cycle ends. After connecting to the installation, it is recommended to test in both intermittent and continuous modes to confirm smooth operation and the absence of unusual noises.
