Description
Product Overview
Bosch ABS/ESP control module with hydraulic pump for Peugeot 307, supplied with a short section of wiring harness. This unit is designed for PSA Citroën/Peugeot vehicles and matches the OEM numbers listed below.
Function And Symptoms
The ABS/ESP control module monitors wheel speed sensors and modulates brake pressure to prevent wheel lock and to support stability control functions. Common indications of a failing unit include illuminated ABS or ESP warning lights, reduced braking performance, unusual pedal feel, diagnostic fault codes, or audible pump operation when the system activates. Failures are often caused by electrical faults, corrosion, water ingress, or internal pump/valve wear.
Installation Notes
Replacement should be performed by a qualified mechanic. Typical steps: disconnect the battery, access and unbolt the ABS unit, disconnect electrical connectors and brake lines (prepare fluid capture), fit the replacement unit, refill and bleed the brake system, then use a diagnostic tool to clear faults and perform coding or module pairing if required. Some swaps are direct if part numbers match, but diagnostic verification is recommended.
