Second Hand BMW 3 Series Airbag Control Module

This depends on which generation each car belongs to: the E46 ran until 2006, while the E90 generation began in 2005, so a 2005 car could be either generation depending on build date, and a 2008 car is E90. Modules from different generations are not interchangeable, and even within the E90 there was a facelift in 2008 that may affect SRS system compatibility. Name the exact generation when contacting the breaker, and ask them to confirm the module matches your car's specific SRS setup against your registration before buying.

No, the engine type does not affect airbag control module fitment on the BMW 3 Series — the SRS system is not engine-dependent. What matters is the generation (for example E46, E90, E92, F30), your trim level, and your body style, as these can influence the configuration of the airbag system. Always ask the breaker to verify compatibility against your registration to be sure.

Trim level can potentially matter for the airbag control module on the BMW 3 Series, as different trims such as SE, ES, M Sport, and Sport may have different seat types or side-airbag configurations that affect the SRS setup. However, whether this makes the module itself incompatible is not something that can be stated as a blanket rule — you should confirm with the breaker against your registration. Give the breaker your exact trim level alongside your generation and body style when requesting a quote.

Body style and door count can affect airbag system configuration, so a module from a Touring estate or a two-door Coupe (E92) may not match a four-door saloon (E90) even within the same generation. The number and placement of airbag sensors can differ between body styles, which matters for the control module. Tell the breaker your exact body style and door count alongside your generation so they can check compatibility against your registration.

Airbag control modules are safety-critical components, and Findapart strongly recommends having this part fitted by a qualified professional rather than attempting a DIY installation. Incorrect fitting or coding errors can prevent airbags from deploying in a crash, or cause accidental deployment, both of which are extremely dangerous. A professional will also be able to ensure the module is correctly coded to your car's SRS system.

Make sure the module is from the same generation as your car — for example E46 (up to 2006), E90/E91/E92/E93 (2005–2013), or F30/F31 (2012–2019) — and that the body style and trim level match where relevant. Airbag modules are single-use after deployment, so confirm with the breaker that the unit has never been triggered and comes from an undeployed system. Also ask the breaker to verify the specific SRS system compatibility against your registration, as pretensioner variants and exact module specs can vary within a generation.
