Description
Overview
ATE ABS/ESP control unit (hydraulic pump and electronic module) suitable for Citroën C3 1.4 HDi 66 kW. Supplied with a section of wiring. Tested, fully functional. Frequently searched by product numbers, improving findability in parts databases.
Function
This unit combines the ABS pump, hydraulic valve block and electronic control module to monitor wheel speed sensors and modulate brake pressure, providing anti-lock braking (ABS) and electronic stability control (ESP) functions. It regulates hydraulic pressure during braking to prevent wheel lock and support vehicle stability interventions.
Fitment & Compatibility
Designed to fit Citroën C3 models with the 1.4 HDi 66 kW engine and compatible with a range of PSA Peugeot/Citroën applications. Always verify compatibility using the listed product codes and your vehicle VIN before installation.
Installation Notes
- Disconnect the negative battery terminal before work to avoid short circuits.
- Access the ABS hydraulic unit in the engine bay; remove any necessary covers and brackets to reach the module.
- Carefully disconnect electrical connectors and brake lines; cap lines to prevent contamination and fluid loss.
- Unbolt the module and remove it from its mounting; install the replacement unit and tighten to manufacturer torque specifications.
- Reconnect wiring, refill brake fluid and perform a complete brake bleeding procedure to remove air from the system.
- Clear fault codes and perform an ABS/ESP system check with compatible diagnostic tools after installation.
Common Failure Modes
Typical causes of ABS/ESP unit failure include internal pump motor wear, valve block contamination or blockage, corrosion from moisture and road salt, damaged electrical connectors, and electronic component faults. Symptoms include illuminated ABS/ESP warning lights, abnormal brake pedal feel, unusual pump noise, or loss of ABS/ESP functionality.
