Installation Guide

The installation of the Metzger 0900647 follows standard procedures for rear wheel speed sensors in the Mercedes C‑Class W204. Below is a step‑by‑step outline:

1. Safety First: Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Remove Old Sensor: Locate the rear wheel speed sensor housing on each axle. Use a suitable socket set to unscrew the mounting bolts, then gently pull the sensor out of its cavity.
3. Inspect Mounting Surface: Clean any debris or corrosion from the sensor slot using a soft brush and isopropyl alcohol.
4. Install New Sensor: Align the Metzger 0900647 with the mounting holes. Secure it with the original bolts, ensuring a snug fit without over‑tightening.
5. Reconnect Wiring: Attach the sensor’s electrical connector to the vehicle’s harness. Verify that the pins are correctly seated and that no wires are pinched.
6. Test Functionality: Reconnect the battery, start the engine, and observe the ABS indicator on the instrument cluster. A steady light or a brief flash indicates proper sensor operation.

Maintenance Tips

• Regularly inspect the sensor connector for corrosion or loose pins.
• Check the sensor housing for cracks or damage that could compromise sealing.
• If the ABS warning light remains illuminated after replacement, perform a diagnostic scan to rule out wiring faults or ECU issues.
