Description
Control Module, ABS Pump, ESP Unit, ABS Block Bosch Peugeot 307
Overview
This Bosch ABS/ESP control unit and hydraulic pump assembly is designed for Peugeot 307 braking systems. It combines the electronic control module with the high-pressure pump and hydraulic block to manage Anti-Lock Braking (ABS) and Electronic Stability Program (ESP) functions. Ideal for professional workshops and experienced DIY mechanics, this unit restores proper ABS modulation, traction control intervention and stability assistance when the original module has failed.
Key Benefits
Reliable Bosch engineering with direct fitment for compatible Peugeot 307 models. Replacing a faulty ABS/ESP module eliminates wheel lock-up, reduces stopping distances under hard braking, and restores ESP interventions that prevent skids. Part numbers commonly searched for and listed below make it easy to find and match the correct unit.
Application And Fitment
Intended For: Peugeot 307 models (commonly used on model years around 2001–2008) equipped with ABS/ESP systems. Always cross-reference Product Codes when ordering to ensure exact match with the vehicle equipment level and manufacture date.
Installation Recommendations
Installation Should Be Performed By A Qualified Technician Or An Experienced DIY Mechanic With The Following Steps Typically Required:
- Disconnect The Battery Before Starting To Avoid Electrical Damage.
- Locate The ABS/ESP Unit (Usually Mounted Near The Brake Master Cylinder Or In The Engine Bay) And Remove Any Protective Covers.
- Carefully Disconnect The Electrical Connector(s) And Label Them If Necessary.
- Loosen And Remove Brake Lines From The Hydraulic Block; Use Proper Tools And Prepare To Capture Brake Fluid.
- Unbolt The Unit From Its Bracket And Remove It From The Vehicle.
- Install The Replacement Unit, Refit Brake Lines Using New Seals If Required, And Torque Connections To Manufacturer Specifications.
- Refill And Thoroughly Bleed The Brake System (Pressure Bleeding Recommended) To Remove All Air From The Circuit.
- Complete Post-Installation Checks With A Diagnostic Tool To Clear Fault Codes And Verify ABS/ESP Functionality.
Note: After replacement, some vehicles require a diagnostic procedure to reinitialize ABS sensors, wheel speed sensors or to clear stored faults. Using Manufacturer Level Diagnostic Equipment Ensures Proper Commissioning.
Why This Part Fails
Common Failure Causes Include Corrosion Of The Hydraulic Block, Electrical Faults In The Control Module, Moisture Ingress, Internal Pump Wear, Or Damage From Contaminated Brake Fluid. Symptoms Often Seen Are ABS/ESP Warning Lights On The Dashboard, Pump Running Continuously, Pulsating Brake Pedal, Reduced Braking Performance Or Intermittent Loss Of ABS Functionality.
