    Genuine BMW ABS Wheel Speed Sensor - Rear 34521181456 - For BMW Vehicles

    Manufacturer Part Number: 34521181456

    Description

    Enhance your BMW's braking performance with the Genuine BMW ABS Wheel Speed Sensor, specifically designed for your vehicle's rear wheels. This premium-grade sensor ensures precise communication with the ABS computer, allowing it to monitor wheel speeds and detect any potential brake lock-up situations. When your ABS system operates effectively, it not only improves safety but also prevents premature tire wear. A faulty ABS sensor can trigger an ABS warning light on your dashboard, so timely replacement is crucial.

    Each vehicle requires two sensors (left-hand and right-hand), and this part is integral to maintaining the effectiveness of your ABS system. When replacing your ABS wheel speed sensor, consider using dielectric grease on the electrical connector to protect it from corrosion and environmental factors, ensuring a long-lasting connection.
