Product Overview

High-quality left roof-side (curtain) airbag designed for the driver’s side of Peugeot 3008 and 5008 first generation vehicles. This original-equipment style airbag restores side-impact and rollover protection for head and upper torso, helping to ensure occupant safety after repair or accident-related replacement. Suitable for professional workshops and experienced DIY mechanics searching by part numbers 9684667880 or 8335WQ.

Function And Application

The roof-side airbag deploys in side impacts and certain rollover conditions to protect the occupant’s head and side of the torso, reducing the risk of serious injury. It is installed along the roof rail/headliner on the left (driver) side and works together with door and seatbelt systems as part of the vehicle’s SRS (Supplemental Restraint System).

Replacement Procedure

• Disconnect the negative battery terminal and wait at least 10–15 minutes (preferably 15–30 minutes) for residual energy in the SRS system to dissipate.
• Carefully remove interior trim and headliner panels to access the airbag module — preserve clips and fasteners for reassembly.
• Unplug the airbag electrical connector (observe connector locking features) and remove mounting bolts.
• Install the replacement unit in reverse order: secure with correct fastener torque, connect the airbag harness with correct locking, and refit the headliner and trim.
• Reconnect the battery and verify SRS status with a diagnostic tool; clear any stored fault codes and confirm the airbag indicator behaves correctly.

Installation Recommendations

Always follow the manufacturer’s service procedures and torque specifications. Use proper interior trim tools to avoid damaging panels. Never probe or modify airbag connectors or wiring. After replacement, perform an SRS system scan with a compatible diagnostic tool and confirm that no warning lights remain. If unsure, have the final check performed by a qualified technician experienced with Peugeot safety systems.

Why This Part Fails Most Often

Roof-side airbags generally do not have a scheduled replacement interval. Typical causes for replacement are deployment during an accident, physical damage to the module or wiring (including damaged connectors or abrasions during previous repairs), and water ingress or corrosion affecting connectors or inflators. Damage during interior work or improper removal/installation can also render the unit inoperative.

Notes For Professionals

This airbag is intended to restore SRS functionality after damage or deployment. After installation, an SRS diagnostic scan is required to confirm circuit integrity and to clear any crash or fault codes. Use original-style connectors and routing to avoid noise or chafing. Keep replacement units in original packaging until installation to avoid contamination or accidental damage.
