Description
Product Overview
This ATE ABS/ESP pump assembly with a short section of wiring is designed for Citroén C5 II applications. The unit combines the electronic control module and hydraulic pump that support Anti-lock Braking System (ABS) and Electronic Stability Program (ESP) functions. Supplied with the listed part numbers, it is often located and purchased by its product code.
What The Unit Does
The ABS/ESP pump modulates hydraulic pressure to individual wheel brakes during ABS events and provides the hydraulic actuation required by the ESP system to stabilise the vehicle. The control module interprets wheel speed sensors and other inputs to operate valves and the pump motor, preventing wheel lock and helping maintain directional control.
Common Symptoms And Causes Of Failure
Typical signs that this module is failing include ABS or ESP warning lights on the dashboard, intermittent braking faults, unusual noise from the pump motor, and loss of ABS/ESP functionality. Common causes are electrical faults (damaged wiring or connectors), internal pump motor wear, valve blockage, and corrosion or water ingress affecting the electronic control unit. Failures are generally associated with long service life, environmental exposure, or impact damage.
Replacement And Installation Notes
Replacement should be carried out by professional technicians or experienced DIYers who have access to appropriate diagnostic and bleeding equipment. General replacement steps: disconnect the vehicle battery, access and unbolt the ABS/ESP module, carefully disconnect brake lines and electrical connectors, fit the replacement unit and wiring section, then perform a full brake system bleed and ABS/ESP system bleed using a compatible diagnostic tool. After installation, clear fault codes and run system calibrations as required to restore proper ABS/ESP operation.
Fitment And Compatibility
Designed for Citroén C5 II (second generation) models and often cross-referenced by part numbers. Always verify compatibility by comparing the unit’s product codes with the vehicle’s OEM references before ordering. This assembly is aimed at mechanics and DIY car owners who search by part number or require a direct-fit ABS/ESP module with wiring included.
