Description
High-quality Bosch ABS/ESP control module and hydraulic pump assembly for Peugeot 307. This unit combines the ABS control electronics with the hydraulic pump and valve block that manage anti-lock braking and electronic stability control (ESP). Customers frequently search by OE numbers; the included references help ensure correct fitment.
Function And Benefits
The ABS/ESP control module monitors wheel speed sensors and modulates hydraulic pressure via the pump and valves to prevent wheel lock-up during braking and to support vehicle stability interventions (ESP). Replacing a faulty module restores ABS pumping action and stability functions, improving braking performance and safety.
Common Failure Modes
Failures typically stem from electrical faults, corrosion or moisture ingress, worn pump motor, or internal valve block issues. Symptoms include warning lights (ABS/ESP), reduced braking performance, continuous pump activation, or loss of ESP functions. Age, road salt exposure and moisture are frequent contributors to failure on PSA vehicles.
Installation & Replacement Notes
Intended for professional mechanics or experienced DIYers. Typical replacement steps:
- Disconnect the vehicle battery before any work on the ABS/ESP module.
- Locate the ABS hydraulic unit in the engine bay (usually near the brake master cylinder) and disconnect electrical connectors and brake lines carefully.
- Unbolt the module and remove the unit. Replace with the correct OE-referenced module and torque fasteners to manufacturer specifications.
- Refit brake lines, then bleed the brake system to remove air. Follow the vehicle manufacturer bleeding sequence.
- After mechanical fitment, connect a compatible diagnostic tool (e.g., PSA Diagbox/Lexia or equivalent) to clear fault codes and perform module coding or parameterization as required by the vehicle ECU.
Note: Proper diagnostic equipment and knowledge of PSA coding procedures are required for full functionality. Always follow safety precautions when working on braking systems.
