ABS 30268 Wheel Speed Sensor

ABS 30268 Wheel Speed Sensor – Precision and Reliability

The ABS 30268 Wheel Speed Sensor is a high‑performance component designed to monitor the rotational speed of each wheel on BMW vehicles. As an integral part of the Anti‑Lock Braking System (ABS) and Electronic Stability Program (ESP), this sensor ensures optimal braking performance, vehicle stability, and safety.

Key Features

• Active Sensor Technology: Provides accurate wheel speed data to the ABS control unit for real‑time brake modulation.
• Compact Design: Lightweight (0.2 kg) and compact, allowing seamless integration into existing sensor mounts without additional space requirements.
• High Durability: Constructed with corrosion‑resistant materials to withstand harsh road conditions, temperature extremes, and continuous vibration.
• OEM Quality: Meets or exceeds original equipment specifications for BMW models such as the 1 Series, 3 Series (E90/E91/E46), and touring variants.
• Easy Installation: Designed to fit standard sensor brackets; no special tools required beyond basic hand tools.

Technical Specifications

Installation Guide

1. Preparation: Disconnect the vehicle battery to prevent electrical shock. Locate the rear wheel sensor bracket on the chosen side (left or right).
2. Removal of Old Sensor: Unscrew the existing sensor using a suitable socket set. Carefully detach the wiring harness, noting the connector orientation.
3. Mounting the New Sensor: Align the ABS 30268 with the bracket and secure it using the supplied screws. Ensure the sensor is firmly seated to avoid misalignment.
4. Wiring Connection: Connect the harness to the new sensor, matching pins exactly as per the diagram. Tighten all connections securely.
5. Testing: Reconnect the battery and start the vehicle. Use a diagnostic scan tool to verify that the ABS system reads the correct wheel speed values. Check for any fault codes related to wheel speed sensors.
6. Final Checks: Inspect all connections, ensure no loose wires, and confirm that the sensor housing is free from debris or damage.

Benefits of Choosing the ABS 30268 Sensor

• Enhanced Safety: Accurate wheel speed detection allows the ABS to modulate brake pressure effectively, preventing wheel lock‑up during emergency stops.
• Improved Vehicle Dynamics: By feeding precise data to ESP, the sensor helps maintain vehicle stability in slippery or uneven conditions.
• Long‑Term Reliability: The robust construction reduces failure rates, ensuring consistent performance over many years of service.
• Cost Efficiency: With a lightweight design and straightforward installation, maintenance costs are minimized compared to aftermarket alternatives.
• Compatibility Assurance: OEM‑grade parts guarantee seamless integration with the vehicle’s existing electronic architecture.

Common Applications

The ABS 30268 sensor is widely used in:

• BMW 1 Series (E81, E82, E87, E88)
• BMW 3 Series (E90, E91, E46, E92, E93)
• Touring and Coupe models across the 2009‑2013 model years
• Both left‑hand drive and right‑hand drive configurations

Maintenance Tips

• Regularly inspect the sensor housing for cracks or corrosion.
• Keep the wiring harness clean and free from moisture to prevent signal interference.
• Replace any damaged sensors promptly to avoid ABS warning lights or reduced braking performance.

Conclusion

The ABS 30268 Wheel Speed Sensor delivers reliable, high‑quality performance for BMW vehicles requiring precise wheel speed monitoring. Its OEM compliance, lightweight construction, and straightforward installation make it an ideal choice for mechanics and vehicle owners alike who demand safety without compromise.
