Mercedes-Benz G-Class Airbag Replacement Parts

The G-Class has run through two main generations: the long-running W460/W461/W463 first generation (from 1979 through to 2018) and the current W464 second generation (2018 onwards), which was a ground-up redesign with an entirely new interior and SRS system. Because the interior architecture changed completely between these two generations, airbags from a W464 will not fit a W463 or earlier, and vice versa. Always confirm the exact generation with your breaker against your registration plate.

A 2015 G-Class is a W463 first-generation car, while a 2019 model is the W464 second generation launched in 2018 — these are entirely different vehicles with different interior structures and SRS systems. Airbags are not interchangeable across this generation boundary, so you need a part from the correct generation. Because airbags are safety-critical single-use components, always have them fitted by a qualified professional and confirm compatibility with your breaker against your registration.

Trim level can matter for the G-Class because seat and interior specifications can differ between standard models and AMG variants, which may affect seat-mounted side airbags in particular. For dashboard and steering-wheel airbags the trim difference is less likely to be significant within the same generation, but you should not assume they are identical. Always confirm the specific airbag location (steering wheel, dashboard, seat, or curtain), your trim level, and your generation with your breaker against your registration, especially for AMG models.

Yes, side absolutely matters for seat-mounted side airbags and curtain airbags, which are handed left (nearside, NS) and right (offside, OS) — fitting the wrong side is dangerous and the part will not locate correctly. When contacting a breaker, always specify NS (passenger side) or OS (driver side) as well as the exact airbag location (front seat, rear seat, or roof curtain). Airbags are safety-critical single-use components and must be fitted by a qualified professional.

Engine type does not affect airbag fitment — the SRS system and airbag locations are determined by the body generation, trim level, and seating layout, not by what is under the bonnet. Provided the generation and trim match, a diesel-donor airbag is no less suitable than one from a petrol car. That said, you should still confirm compatibility of the specific airbag module with your car's SRS system with your breaker against your registration, as airbags are safety-critical components and must be professionally fitted.

Yes, airbags and seatbelt pretensioners are single-use — once deployed they cannot be reset or reused and must be replaced. Used airbags sourced from breakers are undeployed units removed from vehicles that were scrapped for other reasons, and this is standard practice in the UK trade. Because these are safety-critical components, you must have any replacement airbag professionally installed by a qualified technician who can also check and clear the SRS system, and you should confirm with your breaker that the unit is undeployed and matches your car's specification before purchasing.
