Audi A7 4G Front Windscreen Windshield Window Wiper Arm Left N/S 4G2955407B

Audi A7 4G Front Windscreen Windshield Window Wiper Arm Left N/S is an original component from the Wiper arms group, designed for operation on the passenger side. It ensures stable guidance of the wiper blade across the windshield, which translates into a clear field of vision and safe driving in difficult weather conditions. This is a solution for users who expect factory-fitment and predictable wiper system performance.

Purpose and fitment for Audi A7 4G

The presented arm has been designed specifically for the windshield of the Audi A7 4G generation, intended for the left side of the vehicle. The appropriate mounting geometry and correct arm length allow for proper cooperation with the wiper mechanism and blade, without the risk of collision with the hood, pillars, or the other arm. Thanks to a design consistent with factory specifications, the wiper system maintains the correct range of motion, and the pressure of the blade against the windshield remains uniform across its entire length. This is particularly important at higher speeds, where the stability of the arm has a direct impact on the effectiveness of water removal.

Construction and performance parameters

The wiper arm utilizes a lever construction typical for Audi, connecting the mounting point on the mechanism to the blade holder. The applied profile ensures adequate rigidity while reducing weight, which relieves the wiper transmission and reduces loads during operation in rain or snow. Key performance features of this component include:

• precise seating on the splines or cone of the wiper mechanism,
• stable blade mounting, reducing play and vibrations during operation,
• designed pressure angle, allowing for uniform water removal from the windshield surface,
• resistance to typical operational loads, such as operation in rain, snow, and road debris.

Condition, origin, and practical application

The component comes from an Audi vehicle and is classified as used, which means it has been previously operated but is still suitable for further use in the wiper system. For many users, this is a reasonable compromise between cost and maintaining factory geometry and build quality. The arm is intended for installation on the front left side, which is significant both for the range of motion and compatibility with the specific wiper mechanism in the Audi A7 4G. Replacing a worn or damaged arm with an original component of this type allows for restoring proper wiper operation without the need to interfere with other system components.

Benefits of using an original wiper arm

Using an original arm from the Wiper arms category in an Audi A7 4G translates into a number of practical benefits:

• factory fitment to the windshield and mechanism,
• stable blade operation without excessive vibrations or skipping,
• preservation of the windshield cleaning area designed by the manufacturer,
• reduction of the risk of uneven wiper blade wear. For users who want to consciously manage service costs, choosing such a component allows for maintaining the efficiency of the wiper system while preserving high functionality in daily operation.
