Second Hand BMW 4 Series Airbag

The BMW 4 Series first generation (F32/F33/F36) ran from 2013 to 2020, with a facelift in 2017, so a 2014 and a 2016 car are both pre-facelift and are the most likely candidates for a match within that generation. That said, whether a specific airbag module is compatible with your car's SRS system is something you should confirm with the breaker against your registration, as control unit pairing can vary. Airbags are safety-critical single-use components, so professional fitting is strongly recommended.

The F-series 4 Series was facelifted in 2017, and interior changes across that boundary mean a direct swap is not guaranteed — you should confirm with the breaker whether the specific airbag from a pre-2017 car is compatible with your post-2017 registration. Generation, trim, and the side (NS or OS for side airbags) all need to match, so have your reg to hand when you contact the breaker. Because airbags are safety-critical and single-use after deployment, always have them fitted by a qualified professional.

Trim level can matter for the 4 Series because seat style and specification vary between grades such as Sport, M Sport, Luxury, and xLine — side or seat-mounted airbags in particular may differ depending on the seat fitted to your car. For steering wheel or dashboard airbags the trim is less likely to be a factor, but it is still worth telling the breaker which trim your car is so they can cross-check. Confirm compatibility against your registration with the breaker before purchasing, and always have airbags fitted professionally as they are safety-critical parts.

Body style can be relevant because the 4 Series was offered as a two-door coupe (F32), two-door convertible (F33), and four-door Gran Coupe (F36), and some airbag locations and fixings may differ between these variants. Always tell the breaker exactly which body style you have along with your registration so they can source the correct part. Airbags are safety-critical components and must be fitted by a qualified professional.

Although the 4 Series shares its F-series platform with the F30 3 Series, the two models have different interior designs and the airbag modules are not necessarily interchangeable — you should not assume a 3 Series part will fit. Raise this question directly with the breaker and provide both registrations so they can check part numbers against your specific SRS system. Airbags are safety-critical and single-use after deployment, so professional fitting is essential regardless of the source vehicle.

To get the right part you should provide your full registration number, the location of the airbag you need (for example steering wheel, dashboard, NS seat, or OS seat), your trim level (such as Sport, M Sport, Luxury, or xLine), and your body style (coupe, convertible, or Gran Coupe). The breaker will use these details to check the part against your SRS system, as airbag module compatibility can vary in ways that are not always obvious from the year alone. Because airbags are safety-critical single-use components, have the replacement fitted by a qualified professional.
