Purpose and function in the ABS system

The presented sensor belongs to the ABS speed sensor category and is designed for operation on the front right side of the vehicle. Its task is to generate a wheel speed signal, which is then sent to the ABS system controller. Based on this data, the vehicle's electronics can:

• regulate pressure in the brake circuit of a given wheel,
• prevent wheel lock-up during intense braking,
• support the operation of electronic stability control and traction control systems.

A properly functioning speed sensor on the front right wheel is crucial for the uniform operation of the entire system, eliminating ABS errors and unwanted system interventions while driving.

Benefits of using an original Audi sensor

As a component dedicated to the Audi brand, the sensor has been designed to maintain compatibility with factory wiring, mounts, and control logic. This translates into:

• a secure fit to the hub and steering knuckle on the front right side,
• stable signal reading without interference,
• reduced risk of errors appearing in the ABS controller memory.

An additional advantage is the presence of dedicated interchangeable numbers, which facilitates part selection by OEM number or reference numbers in service catalogs and diagnostic tools.

Condition, origin, and service application

The offered item is marked as used, which in practice means it comes from disassembly and has been verified for suitability for further use. This type of component is particularly attractive in situations where:

• a quick and economical repair of the ABS system is necessary,
• you are looking for parts with parameters consistent with factory ones,
• you want to avoid problems with fitting low-quality replacements.

Thanks to the preservation of the original geometry and signal characteristics, the sensor works well with the factory controller, which is especially important in vehicles equipped with advanced driver assistance systems.

Selection by numbers and vehicle placement

The product has assigned interchangeable numbers, which allows for its identification in many parts catalogs and facilitates verification of compatibility with a specific equipment version. Additionally, the placement on vehicle parameter clearly indicates that this is a sensor intended for the front right side, which minimizes the risk of errors during ordering and installation.

If you are planning a comprehensive repair or upgrade of the braking zone in your Audi and need other elements from the same group, such as additional sensors, signal cables, or sensor mounts, check the available parts in the Audi ABS speed sensor category.

Support for choosing used electronics and sensors

When selecting a used ABS speed sensor, it is worth paying attention to the compatibility of the OEM number, hardware version, and installation configuration in a specific vehicle model.
