Description
Control Module, ABS Pump, Unit, ABS Block ATE for Citroën C2 and C3, Peugeot 207, with a short wiring harness.
This ATE ABS hydraulic unit is a direct-fit replacement commonly used on Stellantis small cars such as Citroën C2, C3 (including C3 Pluriel) and Peugeot 207. Supplied with a short wiring harness, the unit combines the hydraulic pump and electronic control into one module to restore proper ABS function and braking safety. Technically minded DIYers and professional mechanics will appreciate that this assembly addresses faults that manifest as ABS warning lights, loss of ABS modulation, or unusual brake pedal behavior.
Designed to work with the vehicle’s wheel speed sensors and brake system, the unit modulates brake pressure during wheel slip events to prevent lock-up and maintain steering control under heavy braking. Replacement of the entire assembly is often faster and more reliable than attempting separate repairs to individual valves or the pump motor. Searchable product codes and OE numbers included below make it easy to find the correct part during ordering or when diagnosing a vehicle on the lift.
Technical Information
- Manufacturer: ATE
- Model: Citroën C2, Citroën C3, Citroën C3 Pluriel, Peugeot 207

Recommended Installation
- Disconnect the negative battery terminal before starting work to avoid electrical damage.
- Depressurize the brake system and carefully drain an appropriate amount of brake fluid to prevent spills.
- Disconnect electrical connectors and brake lines from the ABS unit; mark lines if needed for correct reassembly.
- Remove mounting bolts and replace the unit. Refit brake lines and connectors, ensuring fittings are clean and tightened to the correct torque.
- Refill with manufacturer specification brake fluid and perform a complete brake system bleed. For thorough air removal from the ABS hydraulic circuit, use a diagnostic tool to cycle the pump and open valves during bleeding where possible.
- Clear fault codes and perform a test drive to confirm ABS operation and absence of warning lights. Some vehicles may require additional diagnostics or coding after swap.
Why This Part Fails Most Often
- Corrosion And Moisture Ingress: Long-term exposure to moisture and contaminated brake fluid can corrode internal valves and electrical contacts.
- Electric Motor Or Valve Wear: The pump motor and solenoid valves can wear out after many cycles, especially in vehicles with heavy city braking.
- Contaminated Brake Fluid: Particles or degraded fluid can clog valves and cause hydraulic malfunctions.
- Electrical Faults: Damaged wiring, poor ground connections or connector corrosion lead to intermittent errors or a complete loss of communication with the control module.
- Impact Damage: Collision or underbody damage can deform the unit or break mounting points and connectors.
Replacing the complete ATE ABS unit is a practical solution to eliminate recurring faults caused by internal hydraulic or pump failures. Correct installation, use of fresh brake fluid, and a controlled bleed procedure help ensure the new unit delivers reliable ABS performance.
