Description
Product Overview
This ABS ESP ATE pump with an included wiring harness is designed specifically for the Citroën C5 II. Serving as a vital component of the vehicle’s brake system, this pump plays a crucial role in enhancing braking efficiency by supporting the Anti-lock Braking System (ABS) and Electronic Stability Program (ESP). Replacing this unit restores proper brake pressure modulation, improving vehicle control and safety under various driving conditions.
Function and Importance
The ABS ESP pump operates by regulating hydraulic pressure in the brake lines, preventing wheel lock-up during emergency braking and maintaining traction on slippery surfaces. The ESP function further stabilizes the vehicle by reducing oversteer or understeer. Failure of this component can lead to warning lights on the dashboard, reduced braking performance, and compromised vehicle stability.
Compatibility
This ABS ESP ATE pump assembly fits Citroën C5 II models. It is most commonly searched under product numbers such as 9659770580, 10.0960-1165.3, and 10.0206-0233.4, as well as OEM references 4542F0, 4542F1, 4541G1, and 4541G2. Always verify compatibility with your vehicle model and production year before purchasing.
Installation Tips
Replacing the ABS ESP pump should be performed by experienced mechanics or skilled DIY enthusiasts familiar with brake system components. The process involves disconnecting the battery, removing the old pump module, carefully handling brake fluid lines, and reinstalling the new unit including the wiring harness to ensure proper electrical connections. After installation, the brake system requires bleeding to eliminate air and electronic system calibration to reset ABS/ESP control units.
Longevity and Maintenance
ABS ESP pumps are subject to wear primarily due to exposure to brake fluid contamination and electrical faults. Ensuring the brake fluid is changed regularly according to the manufacturer’s service intervals can extend the pump’s lifespan. Prompt replacement is recommended if ABS or ESP warning lights appear, or if brake pedal response feels abnormal.
