Purpose and function in the vehicle

The presented wiper motor has been designed specifically for installation in the rear part of the body, on the tailgate of BMW Touring series cars. Its placement in the Rear area means that it is solely responsible for driving the rear wiper, working in conjunction with the arm and the drive transmission mechanism within the tailgate.

As an element from the Wiper motors and linkages category, the component is responsible for:

• transferring torque to the rear wiper axle,
• stable operation in both continuous and intermittent modes,
• compatibility with the factory BMW wiper control system.

Original origin and fitment for BMW

The motor comes from the BMW parts line, which ensures adherence to factory manufacturing standards and compatibility with the electrical installation and mounts in the tailgate. As a result, installation is predictable, without the need for wiring modifications or adapters, and the entire assembly remains consistent with the manufacturer's original design.

The used nature of the item allows for an economical repair of the wiper system while maintaining the original BMW specification, which is particularly important when servicing fleet vehicles or cars used intensively.

Condition, verification, and service application

The product is offered as a used part, which in practice means it comes from disassembly and may show signs of wear typical for this type of component. This type of solution is often chosen in professional workshops as a reasonable compromise between repair cost and maintaining the original design of the wiper system.

The rear wiper motor will prove useful in situations such as:

• no response from the rear wiper despite functional fuses,
• operation with noticeable jerking or stopping in random positions,
• mechanical damage following a rear-end collision.

Support in selection via OEM and VIN

To correctly select the motor for a specific version of the BMW Touring, it is crucial to use OEM markings and vehicle data. In case of doubts regarding compatibility, it is worth using the selection procedures based on the part number and VIN number described in the expert guide: Why it is worth buying used gearboxes and engines – facts instead of myths. The verification principles contained therein can be successfully applied to the selection of wiper system components as well.
