Fitment on a used airbag varies by vehicle, so a bit of detail goes a long way. Our request form covers what breakers need to know, so every quote you get back is for the correct part:
The W222 S-Class ran from 2013 to 2020, with a facelift in 2017, so a 2014 donor and a 2018 car sit either side of that facelift boundary – the generation is the same but interior trim and SRS system details can differ across a facelift. You should confirm with the breaker that the specific airbag module is compatible with your car's SRS system before buying. Because airbags are safety-critical and single-use after deployment, professional fitting is strongly recommended.
The W221 ran from 2005 to 2013 and the W222 from 2013 to 2020, so these are different generations with different interior architectures and SRS systems. Airbag modules are generally generation-specific, so a direct swap across these two models is very unlikely to be straightforward. Confirm compatibility with the breaker against your registration, and always have airbags fitted by a qualified professional.
Trim level can matter for S-Class airbags because seat style and interior configuration vary between trims such as standard, AMG Line, and Maybach, particularly for seat-mounted side airbags. If you are sourcing a dashboard or steering wheel airbag the trim difference is less likely to matter, but seat-mounted airbags should come from a matching trim where possible. Confirm the exact specification with the breaker against your registration, and have the airbag fitted professionally as it is a safety-critical component.
Yes, side matters – nearside (NS, left) and offside (OS, right) airbags, particularly seat-mounted side airbags, are not interchangeable. When contacting a breaker, specify clearly which side you need and whether it is a front or rear unit. Always have any replacement airbag installed by a qualified technician.
The W222 S-Class was available in both standard wheelbase and long wheelbase four-door saloon and a two-door coupé body, and the body style can affect which airbag modules are fitted, particularly for side and curtain airbags. Make sure you tell the breaker your exact body style alongside your registration so they can match the correct part. Professional fitting is essential for any airbag replacement.
Yes, airbags are single-use devices and cannot be reset or reused once they have fired, so you must only buy an undeployed unit from a breaker. A reputable breaker will confirm the airbag has not been deployed before sale, but it is worth asking this explicitly when you request a quote. Because airbags are safety-critical components, always have them fitted by a qualified professional rather than attempting a DIY installation.
