Used BMW M4 Curtain Airbag

The BMW M4 (F82/F83) ran from 2014 to 2020, so a 2015 and a 2019 car are both within the same generation, which is encouraging for fitment. That said, whether the airbag module is fully compatible with your specific SRS system is something you should confirm with the breaker against your registration before buying. Never fit a used airbag without professional installation, as curtain airbags are safety-critical and are single-use once deployed.

The M4 was offered as both a Coupé (F82) and a Convertible (F83) within the same generation, and the door count and body structure differ between them, which can affect curtain airbag routing and fitment. You should tell the breaker which body style you have – Coupé or Convertible – and confirm compatibility against your registration. As always, have a safety-critical part like a curtain airbag fitted by a qualified professional.

For curtain airbags, trim level is unlikely to be the primary fitment factor – generation and body style matter more. However, seat and interior specification can vary between standard M4 and higher-specification cars with optional packages, so it is worth confirming with the breaker that the airbag module matches your exact SRS system using your registration. Professional fitting is essential, as curtain airbags are safety-critical and non-reusable after deployment.

Curtain airbags are side-specific, so you need to know whether the damaged airbag is on the nearside (NS – passenger side in the UK) or the offside (OS – driver side). Make sure you tell the breaker which side you need when requesting a quote, as the two are not interchangeable. A professional should carry out the replacement, as this is a safety-critical component.

The F82 M4 Coupé and F83 M4 Convertible ran until 2020, when the all-new G82 generation took over, so a 2020 car could potentially be either generation depending on exactly when it was registered. Check your V5C or ask the breaker to cross-reference your registration to confirm which generation you have before sourcing a curtain airbag. This is especially important because parts from the F82/F83 and G82 generations are not interchangeable, and the breaker will need to verify module compatibility with your SRS system regardless.

Curtain airbags are safety-critical components and we strongly recommend they are fitted by a qualified automotive technician or airbag specialist – not as a DIY job. Incorrect installation can result in the airbag failing to deploy in a collision, or deploying unexpectedly, both of which can be extremely dangerous. A professional will also be able to ensure the SRS system is correctly reset and that the replacement module is compatible with your specific vehicle.
