Fitment questions
What years does the Mercedes-Benz B-Class W246 cover, and will a W245 airbag fit it?
The B-Class W245 ran from 2005 to 2011, and the W246 followed from 2011 to 2018 with a facelift in 2014 — these are distinct generations with different interior architectures, so a W245 airbag will not cross over to a W246. If you are unsure which generation your car is, check your registration against the breaker before ordering.
Does a pre-facelift W246 airbag (2011–2014) fit a post-facelift W246 (2014–2018)?
Both sit within the same W246 generation, but the 2014 facelift brought interior updates that may affect airbag module compatibility — you should name this boundary clearly to your breaker and ask them to confirm the part against your specific registration. Never fit a used airbag without professional installation, as airbags are safety-critical, single-use components.
Does the engine size matter when sourcing a used airbag for my B-Class?
No — engine choice does not affect airbag fitment on the B-Class; what matters is the generation (W245 or W246), trim level, and which airbag position you need (for example, driver, passenger, or side). Focus your search on those details rather than whether the donor car was a diesel or petrol.
Will a B-Class airbag from an SE fit my Sport or AMG Line — do trim levels matter?
Trim level can matter on the B-Class because seat design and interior specification vary between grades such as SE, Sport, and AMG Line, particularly for side or seat-mounted airbags. Confirm with the breaker that the donor car's trim matches yours, and always have a used airbag fitted by a qualified technician given its safety-critical nature.
Does it matter whether the airbag is from the nearside or offside?
Yes — side airbags are handed, so a nearside (NS, passenger side) airbag will not substitute for an offside (OS, driver side) one. When contacting a breaker, specify the exact position clearly: driver or passenger, and whether it is a curtain, seat-mounted, or dashboard unit.
Is it safe to buy a used airbag for my B-Class, and will it work with my car's SRS system?
Used airbags are legal to sell and fit in the UK provided they have never been deployed — airbags are single-use and a previously triggered unit must never be installed. Whether a specific used module is compatible with your car's SRS control system is something you must confirm with the breaker against your registration, and professional fitting by a qualified technician is strongly recommended for any airbag replacement.
