A BMW's anti-lock braking system (ABS) sensor is an essential part of the car's safety mechanism. The speed at which each wheel is turning is measured by a speed sensor. If the wheels are not turning at the same speed or if a wheel loses traction, the computer adjusts the braking system to keep of all of the wheels moving at the same speed. This translates to improved vehicle control and reduces the chances of skidding or losing the ability to brake. ABS sensors are located at each wheel or in the car's differential.

Learn how to search effectively to find exactly what you need. Know how to choose an ABS sensor for a BMW and understanding the item description. Learn how to choose the ideal item condition and manufacturer. Finally, understand how to evaluate items and sellers for the best possible eBay experience.
Identifying the Right ABS Sensor for a BMW
Begin by identifying the model and year of the BMW before starting to search for an ABS sensor. Different models and years may have differences in their construction. For example, components that are suitable for a BMW 3 Series may not fit a BMW 5 Series. Also, ensure that you buy the right sensor for the right wheel. For example, front sensors may not work on back wheels or a sensor for the left wheel may not work on the right wheel. Use this as a guideline when searching.
Check the owner's manual for details about the part, for example, whether it fits on the wheel or on the differential. In some cases, a part number may be visible on the old ABS sensor. This can be used for further guidance when selecting a new component. If in doubt, ask the eBay seller whether the ABS sensor offered is designed for the car in question. A knowledgeable seller can guide you in your buying decision.
Original Equipment Manufacturer vs. Third Party ABS Sensors
In addition to finding an ABS sensor that is compatible with the vehicle, consider whether you want an original equipment manufacturer (OEM) or third party component. OEM parts are identical to those fitted to the car when it left the factory. It is important to note that not all BMW parts and components are manufactured by BMW. In most cases, the ABS sensors are made by Bosch. OEM components tend to be more expensive than third party spare parts, but car owners are assured of the same high quality.
Third party spare parts are manufactured by a company other than the one that made the original parts. These parts tend to be cheaper and quality may vary. However, some reputable companies, such as Hella, produce these parts. Before fitting third party ABS sensors to a BMW, research the brand and component by reading customer reviews and viewing information on forums. This usually gives a clear indication of the quality of these products. It is advised that all sensors on the car should be made by the same manufacturer. If you choose a third party sensor for one wheel, then you should consider replacing all of the sensors with the same brand.
Condition of ABS Sensors for a BMW
The final consideration when buying an ABS sensor is the condition of the part. eBay sellers offer these components in a range of conditions, from new to not working. Understanding these definitions is crucial when buying on eBay. The table below lists the item condition specifications and a short description of each of them.
