ABS ESP Pump Bosch Citroën C5 X7 9674797480 0265951416 4541RY

Description

Product Overview

This Bosch ABS ESP pump is designed for Citroën C5 III (X7) models, serving as the central component of the Anti-lock Braking System (ABS) and Electronic Stability Program (ESP). It ensures optimal brake pressure modulation and vehicle stability by controlling the hydraulic brake circuits during emergency maneuvers or slippery conditions. Reliable operation of this pump is critical to maintaining safe braking performance and preventing wheel lock-up.

Function and Importance

The ABS ESP pump modulates brake pressure by compensating for vacuum loss in brake circuits during ABS activation, while the ESP function enhances control during dynamic driving conditions by preventing skidding and loss of traction. Failure of this pump can lead to ABS warning lights, increased braking distances, or loss of electronic stability control, emphasizing the need for timely replacement when faults occur.

Compatibility and Applications

This unit is compatible primarily with Citroën C5 III X7 models and fits various PSA group vehicles with matching OEM codes. It is often sought under product numbers: 9674797480, 0265951416, 4541RY, among others. Confirming compatibility with your vehicle’s VIN or current pump code is recommended before purchase.

Replacement and Maintenance

Replacing the ABS ESP pump typically requires professional tools and knowledge due to the complexity of the braking system. It involves carefully removing the old pump, flushing the brake fluid, and installing the new unit followed by a system bleed to remove air and recalibration using diagnostic tools. Regular maintenance of the brake system and ECU diagnostics can help identify pump wear early, which commonly occurs due to electronic failures or hydraulic wear after prolonged use.
