Application And Function
The unit is an electric-driven hydraulic power steering pump (commonly called an EPS or electric servo pump). It supplies hydraulic pressure to the steering system on vehicles equipped with electro-hydraulic assistance. When operating correctly it provides consistent assist during low-speed maneuvers and parking, while integrating with vehicle electronics to cut power consumption when assistance is not required.
Installation Recommendations
- Disconnect the negative battery terminal before starting work to avoid electrical faults.
- Drain or capture power steering fluid before disconnecting hydraulic lines; expect some fluid loss when removing the unit.
- Inspect and, if needed, replace line O-rings and sealing washers to ensure leak-free connections.
- Ensure the electrical connector and any supplied wiring are undamaged and secure; this unit is supplied with a short harness piece that must be integrated properly.
- After fitting, refill with the manufacturer-specified power steering fluid and bleed the system according to workshop procedures to remove air pockets.
- Perform a vehicle test at low speed to confirm correct assistance and check for leaks; re-check fluid level after a short road test.
Most Common Failure Reasons
Failures typically result from a combination of hydraulic and electrical issues: deteriorated seals or leaking hydraulic lines lead to fluid loss and contamination; internal wear or contamination can reduce pump output; electrical motor failure or damaged connectors disrupt the pump drive; and blocked or contaminated fluid accelerates wear. Corrosion of fittings and heat-related degradation of internal components are also common causes on higher-mileage vehicles.
Why Choose This Unit
Searchable by the listed part numbers, this pump is suited for technicians who need a straightforward replacement that fits the cited Citroën and Peugeot models. The supplied wiring piece helps streamline installation where connectors have been repaired or modified. For best results, fit the unit alongside fresh seals and proper fluid and follow a complete bleeding procedure.
