Purpose and function in the steering system

This electric power steering rack has been designed to work with a power steering system based on an electric motor and control unit, allowing for precise transmission of steering input to the front wheels. Using an original steering rack in the Passat B7 and Jetta Mk6 helps maintain:

• correct power steering characteristics across the entire speed range,
• stable vehicle handling at higher speeds,
• proper cooperation with safety systems (ESP, traction control, driving assistants).

Benefits of using an original steering rack

Using an original steering rack in a Volkswagen chassis translates into a number of practical service and operational benefits:

• Factory fit – maintaining proper geometry, mounting points, and compatibility with the steering column.
• Consistency with vehicle electronics – correct communication with control modules and torque sensors.
• Possibility of adaptation and calibration using standard diagnostic procedures used in VW service centers.
• Reduction of the risk of improper steering operation, play, or uneven response to steering wheel movement.

Condition, verification, and preparation for installation

The component comes from an operated vehicle and is offered as a used part, which represents a reasonable compromise between repair costs and maintaining original structural quality. Before installation, a standard service procedure is recommended, including checking mounting points, boots, electrical connectors, and performing system adaptation after installation.

The steering rack is intended for direct installation in place of the factory component, using original mounting points and connections. Proper installation and subsequent calibration of the steering system allow for restoring correct vehicle handling and power steering comfort.

Application in Volkswagen Passat B7 and Jetta Mk6

The offered steering rack is dedicated to Passat B7 and Jetta Mk6 models with electric power steering, which facilitates part selection for post-collision repairs, replacement of worn components, or mechanical damage. Thanks to the preservation of the original design, it is possible to:

• maintain the factory turning radius and handling characteristics,
• ensure proper operation of driver assistance systems,
• maintain predictable vehicle behavior in emergency situations.
