• Seamless Integration: Compatible with standard ABS/ESP architectures used in many modern cars.

Technical Specifications

Compatibility Overview

The sensor is engineered to fit a broad spectrum of vehicles that employ Bosch’s wheel speed sensing technology. Common applications include:

• Mercedes‑Benz C‑Class (W204, S204) – front and rear wheels.
• Various Mercedes‑Benz models with OE# 2045400117 or A2045400117.
• Other OEM vehicles that use the WS545 sensor architecture.

When selecting a replacement, verify the vehicle’s year, model, and wheel hub specifications to ensure a perfect fit. The sensor’s modular design allows for straightforward swapping of left or right side units without requiring additional adapters.

Installation Guide

1. Safety First: Disconnect the vehicle battery to prevent accidental electrical discharge.
2. Remove Old Sensor: Detach the wheel, locate the sensor on the hub, and unscrew it carefully. Note any orientation marks or cable routing.
3. Prepare New Sensor: Align the mounting flange with the hub’s bolt pattern. If a cable is included, route it along the original path to avoid tangling.
4. Screw in Place: Tighten the sensor bolts to the manufacturer’s torque specification (typically 20–25 Nm).
5. Reconnect Battery: Reattach the battery and power on the vehicle. Use a diagnostic tool to confirm that wheel speed data is being transmitted correctly.

Maintenance Tips

• Inspect the sensor’s cable for fraying or damage during routine maintenance checks.
• Avoid exposing the sensor to corrosive substances such as road salt; if contact occurs, clean gently with a non‑abrasive cloth.
• Check for proper alignment after any wheel repair or replacement to maintain accurate speed readings.
