Description
High-quality Bosch ABS Pump and Control Module designed as a direct replacement for PSA vehicles. This ABS hydraulic unit with integrated electric motor and valve block restores anti-lock braking function and wheel-slip control when the original pump fails. Ideal for professional workshops and experienced DIY mechanics seeking a reliable fit under original product codes.
Key Features
- Direct-fit replacement for Citroën and Peugeot models listed below.
- OEM Product Code: 0265800738 with cross-references 4541FF and 4541FG.
- Integrated hydraulic pump motor and valve block to regulate braking pressure under ABS control.
- Restores ABS operation, reduces stopping distance under emergency braking and improves vehicle stability.
Fitment & Compatibility
Compatible with a range of PSA models, most commonly found on Citroën Berlingo II, Citroën Xsara Picasso and Peugeot Partner II variants. Always verify the product code against the vehicle’s VIN or the old unit before ordering. This part is typically searched by its product numbers 0265800738, 4541FF or 4541FG.
Installation & Maintenance
- Disconnect the negative battery terminal before starting to avoid electrical damage.
- Locate the ABS unit (usually mounted in the engine bay near the brake master cylinder or inner fender area).
- Depressurise the brake system, then carefully disconnect the electrical connector and brake lines. Mark the lines to avoid interchange.
- Unbolt the unit from its bracket and remove. Fit the replacement, torque mounting bolts to manufacturer specification and reconnect lines and connector.
- Refill the braking system with the correct DOT fluid, perform a full pressure bleed of all brake circuits and the ABS hydraulic circuit.
- Clear ABS fault codes and run ABS system initialization or adaptation using a diagnostic scanner. The ABS lamp may remain on until codes are cleared and the system is bled and adapted.
Causes Of Failure & Service Life
ABS pumps can fail for multiple reasons: electrical motor wear, internal valve or piston seizure, contamination in the hydraulic system, corroded connectors, or water ingress. Lifespan varies with vehicle use and environment; many units remain serviceable beyond 100,000 km, but failures can occur earlier, especially if brake fluid maintenance has been neglected.
Practical Tips
- Always replace brake fluid when changing the ABS pump to prevent contamination-related failures.
- Inspect electrical connectors and wiring harness for corrosion before installation.
- Use a compatible diagnostic tool to clear codes and confirm pump operation after replacement.
