BMW 545i abs wheel speed sensor typically cost between $29.99 and $37.99.
A BMW 545i ABS wheel speed sensor is a crucial component of the Anti-lock Brake System (ABS) fitted in BMW vehicles. It detects and monitors the speed at which the car's wheels are rotating. This information is sent to the ABS control module, which uses it to prevent the wheels from locking up or skidding during braking, particularly on slippery surfaces. Thus, it plays a critical role in ensuring vehicle stability and control, as well as enhancing overall driving safety.
By maintaining continuous traction with the road surface, the ABS system ensures that drivers can still steer their vehicles while applying brakes heavily. If this sensor malfunctions, the ABS system may not work as intended, which can potentially compromise vehicular safety. Signs of a faulty ABS sensor can include the ABS warning light illuminating on the dashboard and the vehicle skidding during heavy braking.
A BMW 545i has four ABS wheel speed sensors. Each wheel is equipped with one sensor, which is responsible for monitoring the speed at which the wheels are rotating.
The lifespan of an ABS wheel speed sensor can greatly hinge on a range of factors like driving conditions and overall vehicle maintenance. However, in ideal situations, it can last anywhere from 80,000 to 100,000 miles. It's essential to note that as this component is exposed to external elements and constantly working while the car is moving, it may fail earlier than expected. Regular check-ups will ensure that any faults are noticed and rectified promptly to prevent further damage.
Replacing ABS Wheel Speed Sensors On A BMW 545i
First and foremost, before undertaking any maintenance work on your car, it's critical to ensure that you have the correct tools, new speed sensor, and necessary safety equipment. Follow these steps:
- Engage your BMW 545i's parking brake for safety.
- Loosen the lug nuts on the wheel where you'll be replacing the ABS wheel speed sensor.
- Use a jack to elevate that part of the vehicle and then place a jack stand beneath it to ensure stability.
- Completely remove the lug nuts and take off the wheel.
- The wheel speed sensor will typically be located behind the hub of the wheel. Look for a wire leading to the back of the wheel area. You'll need to track this wire to the sensor.
- Unclip the wire from its fastening points as you go along.
- Disconnect the wire connection to the sensor. It may be possible that you will have to remove additional parts such as the brake caliper or rotor for easier access to the sensor.
- Remove the bolt holding the sensor in place, then carefully remove the sensor from the hub.
- Insert the new ABS wheel speed sensor into the hub, ensuring it is securely in place, and replace the bolt.
- Run the wiring from the sensor back along the same route the original was run, attaching it to the fastening clips you unclipped earlier.
- Reconnect the wire connection to the new sensor.
- If you've removed any components for easier access to the sensor, replace them now.
- Reattach the wheel and lightly tighten the lug nuts in a crisscross pattern.
- Lower the car down off of the jack, making sure it is secure and stable.
- Tighten the lug nuts with a torque wrench according to your vehicle's specifications.
- Test drive your car to make sure everything is working properly.
Remember, if you're not comfortable doing this by yourself or you're having difficulties, it's best to have a professional mechanic perform the task.
