Used Vauxhall Astra Airbag

The Astra H ran from 2004 to 2010, with a facelift in 2007, so a 2005 and a 2008 are on opposite sides of that facelift boundary — generation is the same, but whether parts cross that facelift cut-off is something you should confirm with the breaker against your exact registration. You'll also need to specify which airbag you need (steering wheel, dashboard, side, curtain), the door count, and NS or OS where relevant. Because airbags are safety-critical and single-use after deployment, professional fitting is strongly recommended.

No — the Astra J (2009–2015) and Astra K (2015–2022) are different generations with different interior architecture, so their airbag components are not interchangeable. You need to source a part from the correct generation for your car. Always confirm the exact match with the breaker using your vehicle's registration, and have the airbag fitted by a qualified technician.

For most airbag positions (steering wheel, dashboard, curtain), trim level does not typically affect fitment within the same generation and body style — an SE, Design, or Elite unit will generally be the same part. Where trim can make a difference is side airbags built into the seat bolsters, because seat style and upholstery can vary between trims such as SRi (which uses sportier seats) and standard trims. If you're replacing a seat-mounted side airbag, tell the breaker your exact trim level so they can match the seat type, and always have the replacement fitted professionally.

It can matter, particularly for curtain airbags, which are sized to cover the correct number of windows for your body style. Steering wheel and dashboard airbags are generally unaffected by door count, but it's worth specifying your body style to the breaker when quoting to rule out any fitment differences. As with all airbag work, professional installation is essential given the safety-critical nature of the component.

Used airbags are legal to buy and sell in the UK provided they have never been deployed — airbags are single-use, so a breaker should confirm the unit comes from an undeployed, non-accident-damaged system before you purchase. It's also worth asking the breaker to check compatibility of the airbag module with your specific SRS (supplemental restraint system) control unit, as this can vary and is something to confirm against your registration rather than assume. Professional fitting and post-installation system checking are strongly advised for any airbag replacement.

Give the breaker your vehicle registration (they can look up the exact generation, facelift variant, and build date), which specific airbag you need (steering wheel, passenger dashboard, side seat-mounted, or curtain), your door count for curtain airbags, and NS (nearside/left) or OS (offside/right) for any side or curtain unit. Trim level is worth mentioning especially if you need a seat-mounted side airbag, as seat styles differ across trims like SRi, SE, and Elite. The breaker will need to verify module compatibility with your SRS system against your registration, so the more detail you provide upfront the quicker they can confirm fitment.
