Second Hand BMW i4 Curtain Airbag

Yes, the BMW i4 is fitted with curtain airbags as standard across all variants — they run along the roofline to protect occupants in a side-impact or rollover. The i4 is a four-door Gran Coupé body style throughout its range, so all examples share this safety provision regardless of drivetrain or power output.

The BMW i4 launched in 2021 and, as far as current knowledge extends, has not undergone a generation change within that period, so a 2022 and a 2024 car are broadly the same generation. That said, BMW does introduce mid-cycle updates, and airbag module compatibility with a specific car's SRS control unit is something you should confirm with the breaker against your exact registration before buying. Curtain airbags are safety-critical single-use components, so professional fitting by a qualified technician is strongly recommended.

The curtain airbag itself runs along the roofline and is not generally affected by trim level in the way that, say, seat upholstery or interior trim is. However, you should confirm airbag module compatibility against your specific registration with the breaker, as SRS system variants can differ between build specifications. Professional fitting is essential given these are safety-critical components.

Yes, this matters — curtain airbags are handed, meaning the nearside (left, passenger side) and offside (right, driver side) are different parts and are not interchangeable. When contacting a breaker, always specify NS or OS clearly alongside your registration to ensure you receive the correct unit.

Curtain airbags are safety-critical components and their correct function in an accident depends on precise installation and compatibility with the car's SRS system. Findapart strongly recommends having a used curtain airbag fitted by a qualified automotive technician or an approved garage, not as a DIY job. It is also worth noting that airbags are single-use — once deployed, they must be replaced and cannot be refurbished.

Give the breaker your full registration number so they can check the part against your car's specific build — this is especially important for airbags, where SRS module compatibility can vary and is something you must confirm with the breaker rather than assume. Ask whether the unit is undeployed and undamaged, and check whether it comes with any associated brackets or fixings. Given these are safety-critical parts, always have the airbag installed and the SRS system checked by a qualified professional.
