Description
Control Module, ABS ESP Pump Unit, Bosch ABS Block For Citroën C3 2018. Supplied With A Piece Of Wiring.
This Bosch ABS/ESP pump and control module is a direct replacement part intended for Citroën C3 III vehicles and other Stellantis applications that use the same ABS block. Designed for professional workshops and experienced DIY mechanics, the unit restores anti-lock braking and electronic stability control functions when the original module has failed. Customers commonly search by part numbers (OE codes listed below), so this listing includes the most frequent references to simplify identification.
Technical Information
- Manufacturer: Bosch
- Model: Citroën C3 III (example: 2018)
- Product Codes: 0265956240, 1624376280
- Additional Numbers: 1649128180, 1682601580, 265956240
Function
The ABS/ESP pump and control module monitors wheel speed sensors and adjusts hydraulic pressure to individual wheels to prevent lock-up during braking (ABS) and to support vehicle stability control interventions (ESP). The integrated hydraulic unit contains valves and an electric pump that modulate brake pressure, while the electronic control reads sensors and commands the hydraulic components.
Compatibility And Fitment
Intended For Citroën C3 III vehicles (example shown: 2018). Verify the unit reference numbers against the vehicle’s existing part numbers before installation. The same ABS block is sometimes fitted across related Stellantis models—use the OE codes above to confirm interchangeability.
How The Part Is Replaced
- Park The Vehicle On A Level Surface, Chock Wheels And Ensure Stability.
- Disconnect The Negative Battery Terminal And Wait A Few Minutes To Avoid Electrical Damage.
- Locate The ABS Module (Usually In The Engine Bay Or Inner Wing) And Disconnect Electrical Connectors Carefully.
- Label And Loosen Brake Lines Using The Correct Spanners; Prepare To Collect Brake Fluid To Avoid Contamination.
- Remove Mounting Bolts, Extract The Unit Along With The Attached Wiring Section, And Fit The Replacement In Reverse Order.
- After Mechanical Fitment, Refill/Top Up Brake Fluid And Perform A Thorough Brake Bleeding Procedure—Including ABS Pump Activation Routines—To Eliminate Air From The System.
- Run An Electronic Self-Test And, If Available, Use Manufacturer Diagnostic Equipment To Confirm Proper ABS/ESP Operation.
Installation Recommendations
- Always Disconnect The Battery Before Removing The Unit To Prevent Damage To The Electronic Module.
- Use Correct Brake Line Tools And New Sealing Washers Where Required To Prevent Leaks.
- Bleed The Brake System Completely After Installation; Some Vehicles Require ABS Cycling During The Bleed—use A Diagnostic Tool To Execute The Procedure Correctly.
- Inspect Brake Fluid Condition And Replace If Contaminated Or Highly Moisture Laden; Contaminated Fluid Accelerates Component Wear.
- Follow Manufacturer Procedures For Mounting Torque And Connector Seating To Avoid Mechanical Or Electrical Issues.
Most Common Failure Reasons
- Electrical Faults Caused By Corrosion Or Poor Connector Contact.
- Hydraulic Component Wear Or Valve/Seal Failure Inside The Pump Unit.
- Water Ingress Or Moisture Damage Leading To Internal Corrosion.
- Contaminated Or Neglected Brake Fluid Causing Internal Blockage And Accelerated Wear.
- Impact Damage From Collisions Or Road Debris Affecting The Unit Or Its Mounting.
