Metzger 900179 Sensor Ring, ABS

Metzger 900179 Sensor Ring – ABS

The Metzger 900179 Sensor Ring is a precision‑engineered component designed to restore the functionality of an ABS (Anti‑Lock Braking System) on rear axles. Crafted from high‑strength, heat‑resistant ABS plastic, this sensor ring delivers reliable performance under demanding driving conditions while maintaining lightweight characteristics that benefit overall vehicle dynamics.

Key Features

• High‑Durability Material: Made from premium ABS polymer capable of withstanding extreme temperatures and mechanical stresses.
• Exact Fitment: Engineered to match the original mounting geometry, ensuring seamless integration without modification.
• Signal Integrity: Provides accurate wheel speed data to the vehicle’s electronic control unit (ECU), essential for safe braking and traction management.
• Corrosion Resistance: Resistant to road salts, moisture, and chemical exposure, extending service life in varied climates.

Technical Specifications

Compatibility Overview

The Metzger 900179 Sensor Ring is engineered to fit a broad spectrum of rear‑axle configurations across several vehicle families. Below is an illustrative list of models that have been verified for compatibility:

• Volkswagen: Golf V (Mk5), Golf VI, Passat B6/B7, Touran, Tiguan, Beetle, Caddy, and various Mk4/5 derivatives.
• Audi: A3, Q3, TT, A1, A2, A4, A5, A6, A7, A8, and all associated variants (including Sportback and Cabriolet).
• Seat: Leon, Alhambra, Ateca, Tarraco, Ibiza, and all related models.
• Skoda: Octavia, Superb, Yeti, Kodiaq, Kamiq, and other mainstream Skoda vehicles.

For each model, the sensor ring aligns with the original mounting points on the rear axle housing, ensuring that wheel speed data is transmitted accurately to the vehicle’s electronic control unit (ECU).

Installation Procedure

1. Preparation: Safely lift the vehicle and secure it on jack stands. Remove the rear wheels to access the axle assembly.
2. Removal of Old Ring: Locate the existing sensor ring on the rear axle housing. Use a suitable socket or wrench to loosen and remove the mounting bolts, then gently slide the old ring off.
3. Inspection: Examine the axle housing for any damage or debris that could affect fitment. Clean the surface with an appropriate solvent if necessary.
4. Installation of Metzger Ring: Position the new Metzger 900179 Sensor Ring onto the axle housing, aligning it precisely with the mounting holes. Secure it using the original bolts, tightening to the manufacturer’s torque specification (typically 20–25 Nm).
5. Reassembly: Replace the rear wheels and lower the vehicle. Verify that all fasteners are properly tightened.
6. ECU Check: Power on the vehicle and allow the ABS system to initialize. Use a diagnostic scan tool to confirm that wheel speed sensors are reporting correctly and that no fault codes remain related to the rear axle sensor.

Maintenance Tips

• Regular Inspection: Periodically check for signs of wear or damage on the sensor ring, especially after driving in harsh conditions (salted roads, gravel).
• Cleanliness: Keep the axle housing and surrounding area free from oil, grease, and debris that could interfere with sensor operation.
• Avoid Over‑Torqueing: Excessive torque on mounting bolts can deform the ring or damage the axle housing. Use a calibrated torque wrench.

Quality Assurance & Compliance

The Metzger 900179 Sensor Ring adheres to stringent automotive industry standards, including:

• ISO 9001: Quality management system certification ensures consistent manufacturing processes.
• Automotive Part Approval (APA): Meets the performance and reliability criteria set by vehicle manufacturers.
• Environmental Compliance: Designed to meet REACH regulations, minimizing hazardous substances in production.

Conclusion

The Metzger 900179 Sensor Ring – ABS is a reliable, high‑quality component that restores essential braking functionality across a wide range of Volkswagen, Audi, Seat, and Skoda vehicles. Its robust construction, precise fitment, and proven compatibility make it an ideal choice for technicians and vehicle owners seeking to maintain optimal safety performance on the road.
