Second Hand Mercedes-Benz GLB Curtain Airbag

Yes, curtain airbags are fitted to the Mercedes-Benz GLB as standard across the range — they run along the roofline above the side windows to protect occupants in a side-impact or rollover. Because the GLB is offered in a five-seat and a seven-seat configuration, the curtain airbag on your car may differ depending on which layout you have, as the seven-seat version extends coverage to the third row. Always confirm the exact part against your registration with the breaker.

The Mercedes-Benz GLB (X247) launched in 2020 and received a facelift in 2023, so a pre-facelift curtain airbag and a post-facelift one may differ — even though the generation name is the same. The 2023 facelift updated interior and safety systems, which can affect airbag module compatibility with the SRS control unit. Name the generation boundary to the breaker and ask them to confirm against your specific registration before buying.

The GLB is sold in the UK in trims including Sport, AMG Line, and AMG Line Premium, and while trim affects interior specification and seat style, the curtain airbag itself runs along the roofline and is not generally a trim-specific part within the same body configuration. However, if your car has the optional seven-seat layout, that is more likely to affect airbag length and coverage than trim level alone. Confirm your seat configuration and trim with the breaker to be sure.

No — curtain airbags are side-specific, so a nearside (passenger side, NS) airbag cannot be used in place of an offside (driver side, OS) airbag, and vice versa. When contacting a breaker, always specify whether you need the NS or OS curtain airbag for your GLB. Given that airbags are safety-critical components, professional fitting by a qualified technician is strongly recommended.

A curtain airbag that has never been deployed can be reused, but it must be confirmed as undeployed and undamaged — deployed airbags are single-use and cannot be refitted. Any reputable breaker should be able to confirm the deployment status of the part before sale. Because curtain airbags are safety-critical, always have the part fitted by a qualified professional who can also check compatibility with your car's SRS system.

No, the engine and drivetrain make no difference to curtain airbag fitment on the GLB — it is an interior safety component that is matched by generation, body configuration (five-seat or seven-seat), and side (NS or OS). Whether your car is a 200d, 220d, 200, or 250e makes no difference to the airbag itself. Focus on confirming your model year relative to the 2023 facelift and your seating configuration when speaking to a breaker.
