The Bosch ESP control unit is a direct-fit electronic brake control module for Peugeot 406 vehicles equipped with ABS and electronic stability systems. It monitors wheel speed and vehicle dynamics to modulate braking pressure, improving traction and stability during emergency braking and slippery conditions.

Key Features

  • Direct replacement for part numbers 0265109089 and 9642933480
  • Integrates ABS, traction control and electronic stability functions
  • Designed for professional workshops and experienced DIY mechanics

When And Why It Fails

Failures are most often caused by age-related wear, moisture ingress, corrosion of electrical connectors, or electrical surges. Common symptoms include ABS/ESP warning lamps on the dashboard, intermittent braking faults, or loss of traction/stability control.

Replacement And Installation

Typical replacement steps (general guidance):

  • Disconnect the vehicle battery before starting work.
  • Locate the ABS/ESP module (commonly mounted on the hydraulic unit in the engine bay) and remove mounting fasteners.
  • Carefully disconnect electrical connectors and any hydraulic lines as required, using appropriate tools to avoid contamination.
  • Install the replacement unit and reconnect all connectors and lines securely.
  • Reconnect the battery. Use a diagnostic tool (DiagBox, Lexia or a compatible ABS/ECU flasher) to code or initialise the module to the vehicle.
  • Bleed the brake system thoroughly to remove any air introduced during the procedure.

Note: Many Peugeot/PSA control units require manufacturer-level diagnostics to fully synchronise the module. If you are not equipped with the proper diagnostic tools, consult a professional workshop.
