Description
Control module, pump, unit, ABS/ESP block ATE Citroën C5. It is from 2006 2.0 HDi RHR estate. Comes with a piece of the wiring harness.
This complete ABS/ESP assembly combines the hydraulic pump and electronic control unit in one compact module designed for Citroën C5 II applications. Ideal for professional workshops and competent DIY mechanics, the unit restores full ABS and ESP functionality when the original module shows hydraulic or electrical faults. The integrated design simplifies replacement compared with separate pump and ECU solutions and is compatible with vehicles that reference the listed part numbers.
Typical symptoms indicating the need for replacement include persistent ABS or ESP warning lights on the dashboard, reduced braking assistance, a pulsating or unresponsive brake pedal, and stored ABS-related fault codes on a diagnostic scanner. Mechanical noise from the pump or intermittent electrical faults are also common indicators. Replacing the unit returns proper anti-lock braking and stability control behavior when repaired or replacement is required.

Installation Recommendations
Work Should Be Performed By A Qualified Technician Or An Experienced DIY Mechanic With Appropriate Tools. Before Starting, Park The Vehicle On A Level Surface, Chock Wheels And Disconnect The Negative Battery Terminal To Prevent Electrical Damage. Carefully Drain Brake Fluid From The System To Avoid Contamination. Remove The Old Unit With Attention To The Hydraulic Lines And Electrical Connectors; Marking Or Photographing Connections Helps Reassembly. When Installing The New Unit, Ensure All Hydraulic Fittings And Connectors Are Clean And Undamaged, Tighten Connections To Manufacturer Specifications, And Refill The Brake System With Fresh, Manufacturer-Specified Brake Fluid.
After Mechanical Installation, Bleed The Brake System To Remove Air. An ABS-Compatible Bleeding Procedure Using A Diagnostic Tool Is Recommended Because The Unit Often Requires Electronic Activation Of Pump And Valves To Fully Purge Air. Electronic Calibration Or Coding May Be Required For Proper Communication With The Vehicle Body Control Systems — Ensure Fault Codes Are Cleared And Perform A Road Test To Verify Proper Operation.
Most Common Failure Causes
ABS/ESP Units Fail Most Frequently Due To Corrosion And Water Ingress, Electrical Connector Or Wiring Damage, Pump Motor Wear, Internal Valve Or Solenoid Faults, And Contaminated Or Aged Brake Fluid. Thermal Stress And Road Salt Exposure Accelerate Corrosion On Hydraulic Components And Electrical Contacts. Intermittent Failures Often Originate From Damaged Wiring Or Poor Grounds Rather Than The Electronic Module Itself, So Inspect The Harness Supplied With This Unit Carefully.
When Replacing The Module, Inspect Brake Lines, Wheel Speed Sensors, And Electrical Connections To Prevent Recurring Faults. Regular Brake Fluid Changes And Ensuring Sealed Electrical Connections Help Extend The Service Life Of ABS/ESP Assemblies.
