Mercedes-Benz CLS Airbag Replacement Parts

Both years fall within the first-generation CLS, which ran from 2004 to 2010 (W219 chassis), so a 2009 car and a 2012 car are actually from different generations — the second-generation CLS (C218) launched in 2011. Because of that generational boundary, you should confirm compatibility with the breaker against your registration before buying, as parts from across that 2010–2011 cut-off may not interchange.

The second-generation CLS (C218) ran from 2011 to 2018, so both a 2014 and a 2016 car sit within the same generation and interior trim architecture is broadly shared across those years. That said, airbag module compatibility with your specific SRS system is something you should confirm with the breaker against your registration, as this is a safety-critical part. Always have airbags fitted by a qualified technician — they are single-use once deployed and must never be reused from a car where they have fired.

For the CLS, trim level can affect airbag fitment because seat style and interior specification vary between grades such as SE, AMG Line, and full AMG variants, and seat-mounted side airbags in particular are matched to the specific seat shell. Tell the breaker your exact trim level and let them cross-reference against your registration to confirm the part is from a matching specification. As with any airbag, professional fitting by a qualified technician is strongly recommended.

No — driver and passenger airbags are completely different parts, designed for their respective sides and positions, so you need to specify which you require when contacting a breaker. The CLS is a four-door coupé, so there is no variation in door count to worry about, but always quote your side (NS for nearside/left, OS for offside/right) when asking about side-mounted or curtain airbags. Airbags are safety-critical and single-use after deployment, so have any replacement fitted by a qualified technician.

The first-generation CLS (W219, 2004–2010) and the second-generation CLS (C218, 2011–2018) are entirely different platforms with different interior structures, so cross-generation fitment is very unlikely. You should only source airbags from the correct generation, and confirm compatibility with the breaker against your registration before purchasing. Because airbags are safety-critical components, fitting must be carried out by a qualified technician.

The C218 generation ran from 2011 to 2018, and while parts from within the same generation are more likely to be compatible, whether a specific airbag module will work with your car's SRS system is something you must confirm with the breaker against your registration — this is a question we cannot answer as fact. Trim level and seat specification also need to match, so give the breaker your full details including trim grade. Airbags are safety-critical and single-use, so always use a qualified technician for fitting.
