Metzger 0900254 Sensor – Wheel Speed

The Metzger 0900254 Sensor is a high‑performance wheel speed sensor designed for the rear right axle of various European vehicles, including Ford, Seat, and Volkswagen models such as the Galaxy, Sharan, and Alhambra. This sensor plays a critical role in vehicle safety systems by providing accurate wheel rotation data to the Anti‑Lock Braking System (ABS) and Electronic Stability Control (ESC).

Key Functionalities

• Wheel Speed Detection: Measures the rotational speed of the rear right wheel with high precision.
• ABS Integration: Supplies real‑time data to the ABS module, enabling effective brake modulation during skids.
• ESC Support: Contributes to stability control by monitoring wheel slip and assisting in corrective actions.
• High Reliability: Built to withstand harsh automotive environments, including temperature extremes, vibration, and moisture.

Technical Specifications

Installation Overview

The sensor is designed for straightforward installation. Mechanics typically follow these steps:

1. Remove the existing wheel speed sensor. Use a socket set to detach the old unit, taking care not to damage surrounding components.
2. Align the new Metzger 0900254 Sensor. Position it so that the magnetic or Hall element faces the wheel’s toothed rim or gear.
3. Screw in place. Secure with the supplied bolts, ensuring a tight fit to prevent vibration.
4. Reconnect wiring harnesses. Match pins precisely; double‑check polarity if applicable.
5. Test functionality. Use an OBD-II scanner or diagnostic tool to confirm that wheel speed data is being transmitted correctly to the ABS module.

Compatibility Highlights

The sensor’s reference number, 0900254, indicates its compatibility with a range of models across multiple brands:

• Ford Galaxy (Rear Right) – Ensures seamless integration with the vehicle’s ABS and ESC systems.
• Volkswagen Sharan (Rear Right) – Provides reliable wheel speed data for safety modules.
• Seat Alhambra (Rear Right) – Maintains optimal braking performance under various driving conditions.

Performance Benefits
