Description
Product Overview
The ATE ABS/ASR Pump is a direct-fit electronic hydraulic control unit intended for Citroën C5 I vehicles. Identified by part number 9641847080, this module combines the hydraulic pump and electronic control functions for anti-lock braking (ABS) and traction regulation (ASR), modulating brake pressure to maintain vehicle stability under braking or low-traction conditions.
Key Features
- Direct replacement for Citroën C5 I ABS/ASR systems.
- Manufactured by ATE and compatible with PSA group vehicles.
- Integrated pump and electronic control unit to manage wheel slip and prevent lock-up.
- Electrical connector and hydraulic port layout matched to original equipment for straightforward fitment.
Symptoms Of Failure
Typical signs of a failing ABS/ASR pump include illuminated ABS or ASR warning lights, reduced or inconsistent braking performance, unusual pump noises during ABS activation, and visible brake-fluid leaks around the unit. Common root causes are electrical faults, internal valve or motor wear, corrosion, and contaminated brake fluid.
Installation Notes
Replacement should be performed by a qualified technician or an experienced DIY mechanic with appropriate tools. Typical procedure: disconnect the vehicle battery, remove electrical connectors and hydraulic lines, unbolt and remove the old unit, fit the replacement pump and reconnect hydraulic and electrical connections, then bleed the brake system thoroughly. After mechanical installation, use a compatible diagnostic tool to initialize, calibrate and, if available, run the ABS automated bleeding procedure to clear air from the system.
When And Why It Fails
Failure timing varies depending on driving conditions and maintenance. Units commonly fail due to ingress of moisture, corrosion of electrical contacts, motor or valve wear, and brake-fluid contamination. Regular brake-fluid changes and inspection of connectors and hydraulic lines can extend service life.
