Cheap BMW i3 Airbag Control Module

Yes, the BMW i3 is fitted with an airbag control module (also called the SRS control unit) as standard across all variants — it manages the airbag and seatbelt pretensioner systems. This applies to both the standard i3 and the i3s performance variant, and to both battery-electric and range-extender (Rex) models. Because the i3 is electric rather than conventionally engined, the drivetrain layout makes no difference to whether this part exists — all versions have it.

The BMW i3 was produced in one generation, running from 2013 through to 2022, but it received a significant facelift in 2017 — cars from 2017 onwards have updated interior and electrical architecture that may affect SRS system compatibility. A module from a pre-2017 car and a post-2017 car sit either side of that facelift boundary, so you should confirm compatibility with the breaker against your exact registration before buying. This is also safety-critical — airbag modules must be professionally fitted.

The airbag control module itself is an interior electrical component, so generation and body year matter far more than trim level for direct compatibility. The i3 was offered in trim levels including base, Suite, Lodge, Loft, and Range Plus at various points in the UK, and while seat style and interior finish vary between trims, the SRS control module is not a trim-cosmetic item. That said, you should always confirm the specific module reference against your registration with the breaker, as pretensioner variants can differ in ways that are not immediately obvious.

For the airbag control module specifically, the drivetrain — whether full electric or range-extender — does not determine which module is fitted, as this is an interior safety system unrelated to the powertrain. What matters more is the model year and whether the car is pre- or post-2017 facelift. Always quote your registration to the breaker so they can verify the exact part reference, as SRS system variants can be subtle.

The i3s shares the same bodyshell and generation as the standard i3, so in principle the airbag control module should be the same component, but you should confirm this against your registration with the breaker rather than assume interchangeability. The i3s has a wider body kit and firmer suspension, but these are not factors that affect the SRS module. As with all airbag components, professional fitting is strongly recommended — this is a safety-critical part.

An airbag control module that has been involved in a deployment event is a single-use component — once triggered, it should be replaced rather than reused, and a reprogrammed or 'crash data cleared' unit may not meet safety standards. When buying from a breaker, always confirm the module came from a non-deployed vehicle and ask for any supporting information they can provide. Professional fitting and, where required, coding to your vehicle is essential for this safety-critical part — do not attempt a DIY installation.
