The Bosch ABS/ESP control module with integrated pump and hydraulic block is designed for PSA vehicles, primarily Citroën C4 and Peugeot 307. It controls anti-lock braking (ABS) and the electronic stability program (ESP), modulating brake pressure and operating the high-pressure pump to prevent wheel lock and help stabilize the vehicle during emergency maneuvers.

Compatibility

Suitable For Citroën C4 And Peugeot 307 Models. Customers Frequently Search By Part Numbers 9663617980 And 0265234396 To Find The Correct Unit.

Common Failures And Causes

  • Electronic Faults: Internal control electronics can fail and trigger ABS/ESP warning lights or error codes.
  • Pump Wear: The hydraulic pump can deteriorate over time or after prolonged use, especially with contaminated brake fluid.
  • Connector Corrosion: Moisture Infiltration Or Corrosion On Electrical Connectors Causes Intermittent Or Permanent Faults.

Replacement And Service Notes

Typical Replacement Procedure (Summary): Scan For Fault Codes; Disconnect The Battery; Contain Or Drain Brake Fluid; Disconnect The Electrical Connector; Unbolt The ABS/ESP Unit; Remove And Cap Brake Lines To Prevent Contamination; Fit The Replacement Unit; Reconnect Electricals And Hydraulic Lines; Refill And Completely Bleed The Brake System; Clear Fault Codes And Perform A Controlled Road Test. A Diagnostic Tool Is Required For Fault Diagnosis, Code Clearing And Module Initialization/Coding Where Applicable.

Practical Tips For Mechanics And DIYers

Always Verify Exact Part Number Against The Vehicle VIN Before Ordering. Confirm That Wheel Speed Sensors, Wiring And Grounds Are Functional Before Replacing The Module. After Installation, Perform A Full Brake Bleed And Use A Diagnostic Interface To Confirm Proper Pump Operation And ESP Functionality. Driving With An Active ABS/ESP Fault Is Not Recommended.
