This left roof (curtain) airbag is a direct-fit replacement for Citroën C8 and Peugeot 807 models. Identified by product codes 1400418980 and 8329SG, the module is designed to protect the occupant’s head in side-impact collisions and rollovers by deploying from the headliner area along the driver’s side. Ideal for professional workshops and experienced DIY mechanics, this part restores the vehicle’s side-impact protection when the original unit has been deployed or damaged.

Key advantages include precise vehicle fitment for Citroën and Peugeot MPV platforms, compatibility with original mounting points and electrical connectors, and straightforward installation when following safety procedures. Because this airbag interfaces with the vehicle SRS system, correct handling and clearance of fault codes after replacement are essential to restore full system functionality.

Technical Information

Installation Recommendations

Always follow proper SRS safety procedures. Recommended steps for qualified technicians or experienced DIYers:

• Switch off the ignition and disconnect the vehicle battery. Allow at least 10–15 minutes for the system capacitors to discharge before working on the SRS components.
• Carefully remove the headliner trim and any clips or covers to access the airbag module. Keep trim pieces intact to avoid damage.
• Unplug the airbag electrical connector(s) and remove the fasteners securing the module. Handle the module with the trim side away from your body.
• Fit the replacement airbag using original mounting points and torque specifications where available. Reconnect the electrical connector securely.
• Reconnect the battery, use a diagnostic tool to check and clear SRS fault codes, and verify that the airbag indicator on the dash operates correctly.
• If you discover deployed components, damaged connectors, or corrosion, inspect related wiring and the airbag control unit before completing the repair.

Reason For Failure

Roof/curtain airbags typically require replacement after deployment in an accident. Other common causes of failure or removal include water ingress from a leaking sunroof or seals, damage during interior repairs or collisions, connector corrosion, or incorrect previous removal/installation. Physical damage to the module or wiring and fault codes from the SRS control unit are common indicators that the unit no longer provides protection and must be replaced.

Function

The roof/curtain airbag is part of the Supplemental Restraint System (SRS). It deploys in side-impact or rollover events to reduce the risk of head injury by cushioning and reducing contact with the vehicle interior and external objects. Airbags are single-use safety components and must be replaced after deployment.

Installation Recommendations

• Disconnect the vehicle battery and wait at least 10 minutes to ensure the SRS capacitors discharge before starting work.
• Remove interior trim and headliner panels carefully to access the airbag module. Keep fasteners and trim clips organized for reassembly.
• Unbolt the airbag module and disconnect electrical connectors. Inspect connectors and wiring for corrosion or damage and replace any compromised parts.
• Fit the new airbag in the original orientation, secure fasteners to the manufacturer-specified torque, and reconnect electrical connections ensuring proper engagement.
• After reassembly, use an appropriate diagnostic tool to read and clear SRS fault codes and confirm the airbag circuit is operational. Verify the SRS warning lamp behavior per vehicle specifications.
• Follow vehicle manufacturer repair instructions and safety procedures. If unsure about any step, have the replacement carried out by a qualified technician.

Why The Part Most Often Fails

• Deployment During A Collision: Airbags Deploy Once And Must Be Replaced After Activation.
• Electrical Faults: Corroded Or Damaged Connectors, Wiring Harness Issues, Or Faulty Sensors Can Prevent Proper Function.
• Water Intrusion Or Moisture Damage: Leaks Around Roof Seals Or Sunroof Areas Can Cause Corrosion And Electrical Failures.
• Previous Improper Repairs: Incorrect Reassembly Or Damage During Earlier Work Can Compromise The Module Or Its Mounts.
• Age-Related Degradation: While Airbags Are Designed For Long Service Life, Associated Components (Connectors, Clips, Mounts) Can Deteriorate Over Time.

Part numbers listed above are commonly used when searching for compatible replacements. Ensure the physical appearance, mounting points and connector type match the vehicle before installation to guarantee fitment.
