Purpose and function in the vehicle

The presented wiper motor is dedicated for installation on the rear window, in the tailgate area. It is responsible for driving the wiper arm, performing:

• smooth operating movement across the glass surface,
• cooperation with the factory wiper switch,
• support for intermittent and continuous operation modes (according to vehicle configuration),
• correct parking of the arm in the rest position.

Thanks to the precise fit for the specific generation of Audi A3 8P and A4 B7, this component allows maintaining the factory characteristics of the rear window wiper system.

Construction and fitment to the wiper system

The rear window wiper motor in these Audi models is integrated with a gearbox that transfers torque to the wiper arm axis. The design has been engineered to:

• ensure stable mounting in the tailgate,
• allow for a sealed passage of the axis through the glass,
• maintain compatibility with the factory electrical harness,
• operate within the typical Audi angular range, matched to the shape of the glass.

Proper fitment to the original wiper arm and linkage reduces the risk of vibration, noise, and uneven water clearing.

Benefits of using an original Audi motor

Using an original rear window wiper motor in the Audi A3 8P and A4 B7 brings a number of practical benefits:

• Factory fit – no need for modifications to mounts or the electrical installation.
• Stable operation in operational conditions – design intended for operation in moisture and variable temperatures.
• Compatibility with vehicle electronics – proper cooperation with control modules and safety systems.
• Reduced risk of errors and warning messages on the instrument cluster.

Choosing an original component from the Wiper motors and linkages group is the preferred solution for professional windshield cleaning system repairs.

Characteristics of the used component

The offered rear window wiper motor is a used component, which allows for a significant reduction in repair costs while maintaining the manufacturer’s original specifications. This type of part is particularly attractive when:

• the existing motor has suffered mechanical or electrical damage,
• there are problems with the wiper stopping in random positions,
• the motor operates with a noticeable drop in power or irregularly.

Selecting a used OEM component for a specific Audi model allows for maintaining the technical consistency of the vehicle without the need to use replacements with uncertain parameters.

Matching by numbers and additional materials

When selecting a rear window wiper motor, it is worth using the OEM part number and interchangeable numbers to precisely confirm compatibility with a specific equipment version. In workshop practice, the vehicle’s VIN is also often used, which minimizes the risk of purchasing an incorrect component. A detailed discussion of the principles of selecting used drive and electrical components, along with a cost analysis, can be found in the article Why it is worth buying used gearboxes and engines – facts instead of myths, which also covers issues of verifying OEM numbers.
