Purpose and function in the vehicle

The presented motor is dedicated to installation in the rear of the vehicle, where it is responsible for driving the wiper arm. Its task is to smoothly transfer torque to the wiper mechanism so that the movement across the glass is even and stable. As a result, the system effectively removes water, mud, and fine debris from the rear window, supporting safe maneuvering, especially when reversing and driving in the rain.

The motor works with the factory Audi electrical system, which facilitates installation and allows for maintaining the original control logic from the switches in the cabin. Using the correct drive component reduces the risk of overloading the wiper mechanism and incorrect operation in extreme ranges of motion.

Construction and performance parameters

As an element from the Wiper motors and linkages category, this motor is designed to operate in variable weather conditions, taking into account exposure to moisture and temperature fluctuations. The housing and seals are constructed to protect the electrical part and the gearbox from the ingress of external contaminants. The drive is optimized for the torque required for the rear wiper, which allows for:

• stable operation at various wiping speeds,
• proper arm positioning after the cycle is completed,
• maintaining the correct range of motion on the glass.

Selecting the right motor for the rear zone of the vehicle reduces the risk of excessive wear of the mechanism and also minimizes the noise generated during wiper operation.

Condition, origin, and benefits of choosing a used component

The offered motor is a used component, which allows for significantly reducing repair costs compared to purchasing a new part, while maintaining the original manufacturer's specifications. Choosing an original, used component from a donor vehicle is particularly beneficial in the case of systems such as wiper drives, where compliance with the factory installation and proper mechanical fit are important.

A used rear wiper motor is a sensible solution for drivers who want to restore full functionality to the window cleaning system while controlling their service budget. Maintaining the original design translates into predictable system behavior in the long term of operation.

Selection and application in Audi

The motor has been designed with the specific geometry of the tailgate and wiper system in Audi in mind, which facilitates installation and limits the need for modifications. A correctly selected component:

• ensures compatibility with the factory mount and wiper arm,
• works with the original wiring and controls,
• maintains the correct operating angle and resting position of the wiper.

Thanks to this, replacing a damaged drive with the presented motor allows for quickly restoring the efficiency of the rear wiper without interfering with other system components.

If you are planning a comprehensive repair or upgrade of the rear window visibility zone in your Audi and need other elements from the same group, such as drives, linkages, or mechanisms working with wipers, check the available parts in the Audi wiper motors and linkages category.
