3. Clean the Hub Surface: Wipe away any debris or corrosion with a clean rag and mild solvent. A pristine surface guarantees optimal contact.
4. Mount the New Ring: Align the Metzger 0900352 sensor ring onto the hub, ensuring that the metal contacts face outward toward the wheel rim. Tighten the mounting bolts to the manufacturer’s torque specification (typically 20–25 Nm).
5. Reconnect Battery: Restore power and perform a diagnostic check using an OBD-II scanner to confirm that the ABS sensor is reading correctly.

Maintenance & Troubleshooting

The durability of the Metzger 0900352 Sensor Ring means it rarely requires maintenance. However, certain conditions can affect its performance:

• Corrosion or Rust: Inspect the metal contacts periodically; clean with a non‑abrasive brush if necessary.
• Loose Mounting: A loose ring can cause intermittent ABS warnings. Recheck torque after any major suspension work.
• Pulses Not Detected: Verify that the sensor ring is correctly aligned and that no debris blocks the contact points.
• ABS Warning Light: If the light remains on after replacement, scan for fault codes. Common issues include wiring faults or a defective ABS control unit.
