The seat side airbag protects the torso and pelvis during a side impact by deploying from the outer side of the seatback. It is a critical component of the SRS (Supplemental Restraint System) and is designed to reduce injury risk in lateral collisions.

Replacement is typically required after airbag deployment in an accident or if the module or wiring is physically damaged. SRS fault messages can also indicate a defective initiator or damaged wiring under the seat, which often necessitates replacement of the module or associated harness.

Always confirm compatibility by comparing OEM numbers on your original part and visually checking the connector type and mounting points. The included wiring harness reduces installation time and the risk of incorrect connections.

Installation recommendations: disconnect the battery before any work on SRS components and wait at least 10 minutes to allow system capacitors to discharge. Work in an antistatic manner, do not store the module with its frontal side facing down, and protect it from impacts and excessive heat. After installation perform a full SRS diagnostic and clear any fault codes using an appropriate diagnostic tool (for example Lexia/DiagBox).

Overview

This seat-mounted side airbag protects the occupant’s chest and pelvis in a lateral collision. It is designed specifically for the second-generation Xsara (facelift) and is commonly fitted across body styles (hatchback, estate/Break, Coupé) depending on trim and equipment. Confirm compatibility by comparing OEM codes and connector/fastening types with your original part before ordering.

Compatibility And Fitment

Typically found on Citroën Xsara II vehicles produced around 2000–2005 (facelift generation). Fitment depends on the seat trim and equipment level. Always verify the OEM codes stamped on your original airbag and visually compare the plug, harness routing and mounting brackets to ensure correct replacement.

Common Failure Modes

Replacement is usually required after activation in a collision or when an electrical fault is detected by the SRS system. Typical causes include deployed initiators, increased resistance or open circuits in the initiator, damaged wiring in the seat rail area, or connector corrosion. If the vehicle reports a fault tied to this module, replacement and subsequent diagnostic clearing are necessary.

Installation And Aftercare

Installation should be carried out by a qualified technician or an experienced DIYer familiar with SRS systems. Basic recommended steps: disconnect the vehicle battery and follow manufacturer guidance to allow the SRS system to discharge, remove or recline the seat as per the service manual, unclip and remove the original module, fit the replacement unit and secure all retainers, reconnect the connectors and re-fit trim. After installation, perform a full airbag system scan (Lexia/PP2000/DiagBox or equivalent) and confirm the airbag warning lamp extinguishes. Always observe safety procedures and handle modules only in accordance with SRS safety rules.
