Metzger 0900284 Sensor – The Ultimate Wheel Speed Solution for BMW

The Metzger 0900284 Sensor is a precision-engineered wheel speed sensor designed specifically for the rear axle of BMW models ranging from the classic E81/E82 to the modern E90/E92 series. This component plays a pivotal role in vehicle safety systems, feeding critical data to the Anti-lock Braking System (ABS), Electronic Stability Program (ESP), and traction control modules.

Key Functionalities

• Accurate Wheel Speed Measurement: Utilizes a Hall-effect transducer to detect magnetic field changes as the wheel rotates, converting them into electrical pulses that represent real-time speed.
• High Reliability: Built with robust materials and sealed construction to withstand extreme temperatures, vibration, and moisture typical of automotive environments.
• Seamless Integration: Compatible with BMW’s proprietary ABS and ESP control units, ensuring flawless communication without the need for additional adapters or calibration.
• Dual-Side Operation: Available in single or dual (left/right) configurations to support both rear wheels, providing comprehensive coverage for all driving scenarios.

Technical Specifications

Installation Overview

The installation process is straightforward for technicians familiar with BMW rear axle assemblies:

1. Remove the existing wheel speed sensor: Disconnect the electrical connector and unscrew the mounting bolts.
2. Align the new Metzger 0900284 Sensor: Position it so that the magnetic rotor aligns with the wheel’s toothed rim or gear.
3. Secure the sensor: Tighten the mounting bolts to the manufacturer’s torque specification.
4. Reconnect the electrical connector: Ensure a solid connection and verify signal integrity using diagnostic tools.

Diagnostic Compatibility

The sensor’s digital output is fully compatible with BMW’s OBD-II diagnostics. Technicians can use standard scan tools to read pulse frequencies, confirm proper operation, and detect any fault codes related to wheel speed measurement.
