Mercedes-Benz GLC Curtain Airbag Replacement Parts

The GLC runs in two main generations: the first generation (X253) ran from 2015 to 2022, with a facelift arriving in 2019, and the second generation (X254) launched in 2023 onwards. A curtain airbag from a pre-facelift X253 (2015–2019) crossing into a post-facelift X253 (2019–2022) may or may not interchange, and you should confirm compatibility with the breaker against your registration before ordering. A first-generation part will not suit a second-generation (X254) GLC. Never assume fitment across a generation boundary for a safety-critical component like a curtain airbag.

No – curtain airbags are part of the interior safety system and are not related to the engine or drivetrain, so whether your GLC is a diesel, petrol, plug-in hybrid, 4MATIC or otherwise makes no difference to which curtain airbag is required. What matters is the generation (X253 or X254), the trim level, and which side of the vehicle you need (nearside/NS or offside/OS). Always quote your registration to the breaker so they can verify the correct part against your specific SRS system.

Trim level can matter for interior parts on the GLC, as higher-specification trims such as AMG Line may have different headlining or seat configurations that affect how curtain airbags are mounted or routed. It is worth telling the breaker your exact trim level – SE, Sport, AMG Line, or AMG Line Premium – so they can check the donor car matches yours. Curtain airbag module compatibility with your specific SRS system is something you must confirm with the breaker against your registration rather than assume. Because curtain airbags are safety-critical and single-use after deployment, professional fitting is strongly recommended.

Curtain airbags on the GLC run along one side of the roof rail, so you need to specify whether you need the nearside (NS – passenger side in the UK) or the offside (OS – driver's side). Fitting the wrong side is not possible as the parts are handed and will not locate correctly. When contacting a breaker, state the side clearly alongside your registration and generation to get the right part.

Both sit within the first-generation X253 platform, so there is a possibility of overlap, but the 2019 facelift brought interior and trim updates that could affect curtain airbag anchorage points or module specification. You should not assume the part interchanges across the facelift boundary – confirm compatibility with the breaker using your exact registration. As curtain airbags are safety-critical components, it is essential the part is verified correct for your vehicle's SRS system before fitting. Professional installation by a qualified technician is strongly recommended.

Curtain airbags are safety-critical, single-use components that form part of the vehicle's SRS (supplemental restraint system), and fitting one incorrectly can mean it fails to deploy or deploys unexpectedly, with potentially serious consequences. Professional fitting by a qualified technician with the appropriate diagnostic equipment to reset the SRS system is strongly recommended. A used curtain airbag is a viable and cost-effective option from a reputable breaker, but you must ensure the part has never been deployed and is confirmed compatible with your specific GLC's SRS system via your registration.
