Mercedes-Benz Viano Curtain Airbag Replacement Parts

Yes, curtain airbags (also called side curtain or window airbags) were fitted to the Viano, though they were not standard across all variants and trim levels — they were more commonly found on higher-specification models. If you are unsure whether your specific Viano left the factory with curtain airbags, check the sticker inside the driver's door jamb or ask a Mercedes dealer to run your VIN. A breaker can also confirm whether the vehicle they are dismantling matches your spec before you buy.

The Viano was produced in one main generation (W639), running from 2003 through to 2014, with a facelift arriving around 2010 that brought interior and exterior revisions. Generation matters for curtain airbag fitment, so a pre-facelift (2003–2010) part and a post-facelift (2010–2014) part may not be directly interchangeable — confirm the exact model year of both your vehicle and the donor vehicle with the breaker before purchasing. Always supply your registration when requesting a quote so the breaker can check against the correct build specification.

A 2009 Viano is pre-facelift (W639, pre-2010) and a 2011 Viano is post-facelift, so this question crosses the facelift boundary — and while the underlying platform is the same, trim details and interior fittings changed around that time. Whether the specific curtain airbag module is compatible across that boundary is something you must confirm with the breaker against your registration, as SRS system variants can differ. Do not assume fitment without a direct check, especially on a safety-critical component like an airbag.

Trim level can matter for the Viano because seating configurations and interior specifications varied between Ambiente, Trend, and Avantgarde grades, and curtain airbag coverage may differ depending on how the cabin was specced. However, the side (NS nearside or OS offside) and the generation (pre- or post-facelift) are the primary fitment factors you should confirm. Ask the breaker to verify compatibility against your full VIN rather than trim name alone, as factory options could further influence what was fitted.

Yes, curtain airbags are side-specific, so a nearside (NS, passenger side) airbag is not the same part as an offside (OS, driver side) airbag and they are not interchangeable. Always specify which side you need when contacting a breaker, and double-check the side of the donor vehicle's part before agreeing to buy. Curtain airbags are single-use safety components, so fitting the correct part and having it installed by a qualified professional is essential — never fit a used airbag yourself unless you are a trained technician.

Curtain airbags are safety-critical components and must only be fitted by a qualified professional who can properly reset or replace the SRS control module as required — incorrect fitment can mean the airbag fails to deploy in a crash or deploys unexpectedly. Airbags are single-use items, so you must ensure the unit from the breaker has never been deployed and has been stored correctly. Confirm airbag module compatibility with your specific SRS system directly with the breaker against your registration, as this cannot be guaranteed from generation alone.
