• Accurate Speed Measurement: Provides reliable wheel rotation data for the ABS control unit, enhancing braking stability during emergency stops.
• Easy Installation: Designed to fit seamlessly into existing sensor mounts without modification.

Technical Specifications

Vehicle Compatibility Overview

The Metzger 0900744 is engineered to replace the original wheel speed sensor in several popular models. Below is a concise compatibility list:

• Mercedes-Benz Citan – rear‑axle left wheel.
• Renault Kangoo II – rear‑axle left wheel.
• Renault Grand Kangoo – rear‑axle left wheel.
• Other vehicles with the same sensor reference (OE 521) and similar mounting geometry.

Installation Guidance

While the Metzger 0900744 is designed for straightforward replacement, proper installation ensures optimal performance:

1. Disconnect the vehicle’s battery to prevent electrical hazards.
2. Remove the existing wheel speed sensor by loosening the mounting bolts and detaching the wiring harness.
3. Align the new Metzger sensor with the mounting points and secure it using the original bolts.
4. Reconnect the wiring harness, ensuring a snug fit to avoid signal loss.
5. Re‑connect the battery and perform a diagnostic check on the ABS system to confirm correct operation.

Performance Benefits

• Reliability in Extreme Conditions: The sensor’s robust construction resists corrosion, heat, and mechanical shock, providing long‑term reliability.
• Consistent Vehicle Dynamics: By maintaining precise wheel speed feedback, the vehicle’s stability control systems can operate optimally, improving overall handling.

Maintenance Tips

Although the Metzger sensor is designed for durability, routine checks help maintain performance:

• Inspect the wiring harness for signs of wear or damage during periodic maintenance.
• Verify that the sensor housing remains free from debris and contaminants.
• Confirm that mounting bolts are tightened to manufacturer specifications after any service activity.

Conclusion

The Metzger 0900744 ABS wheel speed sensor delivers reliable, OEM‑grade performance for rear‑axle applications in vehicles such as the Mercedes Citan and Renault Kangoo series. Its precise speed measurement capability, durable construction, and straightforward installation make it an excellent choice for maintaining vehicle safety and braking efficiency.
