Cheap Mercedes-Benz GLA Airbag

The first-generation GLA (X156) ran from 2014 to 2019, with a facelift arriving in 2017. A 2015 airbag and a 2018 car are both X156 generation, but the 2017 facelift may have brought changes to the SRS system, so whether a pre-facelift airbag is compatible with a post-facelift car is something you must confirm with the breaker against your exact registration. Never assume fitment across a facelift boundary without that check.

No — the second-generation GLA (H247) launched in 2020 and is a completely different platform to the X156, so airbags from the two generations are not interchangeable. Always source airbags from the same generation as your car and confirm compatibility with the breaker against your registration. Airbags are safety-critical, single-use components and must be professionally fitted.

For seat-mounted side airbags, trim level can matter on the GLA because seat design and upholstery vary between trims such as SE, Sport, AMG Line, and Urban — a seat airbag is built into the seat itself, so you need one from the same trim or at least the same seat type. Dashboard and steering wheel airbags are generally consistent across trims within the same generation, though you should still confirm with the breaker. Airbags are safety-critical and must be fitted by a qualified technician.

Yes, side (curtain and seat-mounted) airbags are specific to the NS (nearside, passenger) or OS (offside, driver) position, so always tell the breaker which side you need. Steering wheel and dashboard airbags are not side-specific in that sense, but the driver airbag differs from the passenger airbag, so be clear about exactly which location you are replacing. Confirm all details against your registration when getting a quote.

Airbags are safety-critical, single-use components — once deployed they cannot be reused, and incorrect installation of a replacement can cause serious injury or death. We strongly recommend having any airbag fitted by a qualified automotive technician or an approved garage, not as a DIY job. Your insurer may also require professional fitting for the repair to be recognised.

The GLA has been offered as a five-door model throughout its production, and door count is relevant mainly for curtain airbags, which run along the roofline and are sized to the cabin length. Confirm the exact part location you need with the breaker and provide your registration so they can match it to the correct unit for your car. As with all airbag work, professional fitting is essential.
