Metzger 0900063 Sensor, wheel speed

Metzger 0900063 Sensor – Wheel Speed

The Metzger 0900063 is a high‑performance wheel speed sensor designed for the front right wheel of vehicles in the Audi, Seat, Skoda, and Volkswagen families. It is an inductive sensor that delivers precise rotational data to the vehicle’s ABS (Anti‑Lock Braking System) and traction control modules, ensuring optimal braking performance and safety.

Key Technical Specifications

• Model: 0900063
• Position: Front Right Wheel (Vorderachse rechts)
• Type: Inductive wheel speed sensor
• Compatibility: Audi, Seat, Skoda, Volkswagen – models ranging from the A3, A4, B1, B2, B3, B4, Caddy, Corrado, Golf (III–IV), Polo, Passat, and Lupo.
• Operating Voltage: 12 V DC
• Signal Output: Pulse frequency proportional to wheel speed
• Temperature Range: –40 °C to +120 °C (typical automotive range)
• Dimensions: Compact design for tight mounting spaces
• Mounting Type: Standard bolt‑in with pre‑drilled holes matching OEM specifications

Design and Construction

The sensor features a robust, sealed housing that protects the internal coil and magnetic core from moisture, dust, and mechanical shock. Its inductive pickup loop is engineered to generate a stable magnetic field, ensuring reliable detection of wheel rotation even under harsh driving conditions.

Functional Benefits

• Accurate Speed Measurement: Provides real‑time data for ABS and traction control systems, enabling precise modulation of brake pressure.
• High Reliability: Designed to withstand vibration, temperature extremes, and exposure to road salts and debris.
• Low Power Consumption: Efficient coil design reduces electrical load on the vehicle’s battery.
• Easy Installation: Matches OEM mounting points; no special tools required beyond standard automotive equipment.

Installation Guide

1. Safety First: Disconnect the vehicle’s battery to prevent electrical shock or unintended activation of safety systems.
2. Remove Old Sensor: Use a socket wrench to loosen and remove the existing wheel speed sensor from the front right wheel hub. Carefully detach any wiring harnesses, noting their orientation.
3. Prepare New Sensor: Inspect the new Metzger 0900063 for any visible damage. Align the mounting holes with those on the hub.
4. Mounting: Secure the sensor using the supplied bolts, tightening to the manufacturer’s torque specification (typically 10–15 Nm). Ensure the sensor is seated flush against the hub surface.
5. Reconnect Wiring: Attach the wiring harness, matching connector pins exactly. Use a crimp tool if necessary and apply electrical tape or heat shrink for added protection.
6. Re‑connect Battery: Restore power to the vehicle’s electrical system.
7. Diagnostic Check: Use an OBD‑II scanner to verify that the sensor is reporting correct wheel speed data. Look for any fault codes related to wheel speed or ABS modules.
