Description
Control module, pump, unit, ABS/ESP block ATE Citroën C5 from 2005 to 2007. Comes with a section of wiring.
This ATE ABS/ESP pump and control module is a direct-fit replacement unit designed for Citroën C5 II vehicles produced in the mid-2000s. The assembly includes the hydraulic pump, electronic control module and a short wiring harness for connector adaptation, making it suitable for fast repairs in the workshop or for experienced DIY mechanics. The unit restores ABS/ESP functionality, improves braking stability and prevents warning lights caused by a faulty pump or module. Commonly searched by part numbers, this product is ideal when diagnosing faults that produce ABS or ESP error codes, reduced braking performance or audible pump noise during system self-tests.

Function And Typical Symptoms
The ABS/ESP pump assembly controls hydraulic pressure for the anti-lock braking system and stability control. It houses the electric pump motor, hydraulic valves and the electronic control unit that interprets wheel-speed sensors and other inputs. Typical symptoms of a failing unit include persistent ABS or ESC warning lights, loss of ABS operation, pulsating braking under normal conditions, unusual pump noise during ignition self-test, or diagnostic trouble codes related to pump motor, internal valve solenoids or communication errors with the ABS ECU.
Why The Part Fails
Failures are usually caused by electrical faults (corroded pins, broken solder joints, or moisture ingress), internal pump motor wear, clogged/contaminated hydraulic valves, or damage from brake fluid contamination. Long-term exposure to road salt and humidity accelerates connector corrosion and electronic failure. In many cases the unit fails after several years of service rather than from a single incident.
Replacement And Installation Recommendations
- Safety First: Park on a level surface, chock wheels and disconnect the vehicle battery before starting work to avoid short circuits and unintended ABS activation.
- Access And Removal: Remove necessary trim and battery to reach the ABS unit location. Disconnect the electrical connector(s) and carefully label or photograph brake line positions before loosening hydraulic lines to prevent mixing errors.
- Hydraulic Lines: Use proper flare wrenches or line wrenches to avoid rounding fittings. Expect a small amount of brake fluid loss—prepare a container and avoid spilling fluid on painted surfaces.
- Replacement: Fit the new unit with the supplied wiring section, secure mounting bolts to the correct torque, reconnect hydraulic lines and electrical connectors ensuring clean, tight connections.
- Bleeding And Initialization: After mechanical installation, perform a complete brake bleed following manufacturer sequence. Use an ABS-capable diagnostic tool to run pump priming, bleed routines and to clear fault codes; some vehicles require electronic initialization or coding of the ABS unit to restore full ESP functionality.
- Final Checks: Verify no leaks, check brake pedal feel and confirm ABS light extinguishes after initialization. Road-test at low speed to confirm normal ABS/ESP operation.
Installation Tips For Mechanics And DIYers
Have a proper ABS-capable scanner available—many modern ECUs need an electronic bleed or system adaptation after replacement. Always replace with the correct part numbers listed above and inspect connectors for corrosion; replace damaged seals or pins to prevent repeat failure. When in doubt about electronic initialization steps, follow manufacturer repair manual procedures or use OE-level diagnostic routines.
