Metzger 0900311 Sensor – Wheel Speed

The Metzger 0900311 is a high‑performance wheel speed sensor designed for modern automotive braking systems. It plays a crucial role in the Anti‑Lock Braking System (ABS) by providing real‑time data on wheel rotation to the vehicle’s control unit, ensuring optimal brake modulation and vehicle stability.

Key Functionalities

• Accurate Wheel Speed Measurement: Utilises a magnetic Hall effect principle to detect wheel revolutions with high precision.
• Reliable ABS Integration: Works seamlessly with the vehicle’s ABS module, enabling rapid brake pressure adjustments during skids or emergency stops.
• Robust Signal Output: Delivers a clean digital signal to the control unit, minimizing noise interference and enhancing system reliability.

Technical Specifications

Compatibility Overview

The Metzger 0900311 is engineered to fit a wide range of vehicles within the Volkswagen Group ecosystem, including:

• Audi models: A4, A5, A6, A8, Q5, R8, and various engine variants.
• Bentley: Continental GT and other high‑performance models.
• Volkswagen: Phaeton, Passat, Golf, Jetta, and commercial vehicles.

Its universal mounting design allows for easy installation on both front and rear wheels, left and right sides, making it a versatile choice for automotive technicians and enthusiasts alike.

Installation Highlights

1. Remove the existing sensor: Carefully detach the old wheel speed sensor from the hub assembly using appropriate tools.
2. Align the new sensor: Position the Metzger 0900311 in the same orientation as the original, ensuring that the magnetic field aligns with the wheel’s rotating components.
3. Screw and secure: Tighten the mounting bolts to the specified torque settings to prevent vibration or misalignment.
