Many customers search and match parts by the product/reference numbers below — always confirm the numbers on your existing unit before purchase.
Replacement And Installation
General replacement steps (overview): disconnect the vehicle battery, remove the trim panels to access the BSI module (typically behind the dashboard or under the steering column on PSA models), unplug connectors and remove mounting fasteners, install the replacement module, reconnect connectors and battery. After physical installation, the unit may require coding, immobiliser synchronization or adaptation to the vehicle’s electronic systems. For these procedures use a compatible diagnostic tool or consult a qualified technician.
Common Failure Modes And Expected Lifespan
BSI units can fail due to internal electronic faults, moisture ingress, corrosion on connectors, voltage spikes or accident damage. Lifespan varies with vehicle conditions and usage; occasional failures are common on higher-mileage vehicles. Regular inspection of connector condition and electrical system health can reduce premature faults.
