Description
Bosch ABS/ESP control module and hydraulic pump assembly for Peugeot 307. This unit combines the anti-lock braking system (ABS) controller with the electronic stability program (ESP) pump and valve block. It manages wheel slip and brake pressure modulation to maintain vehicle stability and optimal braking performance. Includes a piece of wiring.
Common symptoms of a failing unit include ABS or ESP warning lights on the dashboard, reduced braking performance, unusual pump noises during braking, or diagnostic fault codes relating to hydraulic or electrical circuits. Typical causes are electrical faults, corrosion or moisture ingress, mechanical wear of the pump motor, or internal hydraulic valve failures.
Replacement and installation notes: Always disconnect the battery before beginning work. Expect brake fluid leakage when disconnecting hydraulic lines; protect surrounding components and capture expelled fluid. Remove the electrical connectors and mounting hardware, replace the unit, then reconnect hydraulic lines and connectors. After installation the brake system must be thoroughly bled and the ABS/ESP unit may require adaptation or coding using a Peugeot/Citroën diagnostic tool (e.g., DiagBox/Lexia) or a compatible scan tool to clear fault codes and confirm system operation. Professional installation is recommended for safety and correct commissioning.
Compatibility and search tips: Many customers search for this part by its product numbers. Verify the listed codes against your vehicle identification (VIN) or existing part to ensure compatibility. This item is intended for Peugeot 307 and compatible PSA Citroën/Peugeot models using the same ABS/ESP unit.
