Purpose and Function in the ABS/ESP System

The presented pump acts as the central hydraulic-electronic element in the anti-lock braking and stability control system. It is responsible for:

• precise pressure modulation in the brake circuits during emergency braking,
• cooperation with wheel speed sensors and the ESP control module,
• vehicle stabilization during loss of traction through selective wheel braking.

Thanks to this, the ABS and ESP system in Audi S4 B8, A5, and S5 maintains proper operating parameters, which translates to predictable vehicle behavior in emergency situations.

Compatibility and Interchangeable Numbers

The pump is designed as an OEM component for selected Audi models based on the B8 platform. The use of a dedicated controller and appropriate electrical connectors allows for integration with the factory wiring harness without the need for modifications.

The presence of interchangeable numbers allows for easier verification of part compatibility with a specific vehicle configuration. When selecting a component, it is advisable to use the OEM number and references to avoid communication issues between the module and the rest of the system.
