Second Hand Hyundai i40 Airbag Control Module

Yes, the Hyundai i40 was fitted with a Supplemental Restraint System (SRS) including an airbag control module (also called an airbag ECU or SRS module) as standard across the range. It manages the deployment of the airbags and the firing of the pretensioner seat belts. All variants of the i40 — saloon and tourer — carried this unit, so you are looking for a genuine part that exists on this model.

The Hyundai i40 was produced as a single generation (VF) from 2011 to 2019, with a facelift introduced in 2015, so a 2012 module comes from the pre-facelift car and a 2015 module may be either pre- or post-facelift depending on build date. Whether the SRS module crosses that boundary safely is something you must confirm with the breaker against your exact registration, as airbag system calibration can differ across a facelift. Because airbag components are safety-critical and single-use after deployment, professional fitting by a qualified technician is strongly recommended regardless of which unit you source.

Trim level — such as S, Style, Premium, or Premium Nav — can affect the airbag and seat configuration on the i40, for example whether side or curtain airbags are present, which in turn affects what the SRS module is calibrated to manage. You should confirm with the breaker that the donor vehicle's trim level and seat specification match yours, particularly if your car has features such as side-impact airbags in the seats. Always quote your registration to the breaker so they can verify compatibility with your specific SRS system.

The i40 was offered as a saloon and an SW tourer (estate), and the body style could affect the SRS system configuration, as the number and placement of airbags may differ between the two. Confirm with the breaker that the donor car shares the same body style as yours to avoid a mismatch in the module's calibration. This is a safety-critical part, so getting the specification right before purchasing is essential.

Airbag control modules are safety-critical components, and fitting one incorrectly can result in airbags failing to deploy in a crash or deploying unexpectedly, both of which are extremely dangerous. Professional fitting by a suitably qualified technician with the ability to clear and recode the SRS system is strongly recommended. Additionally, if the original module was triggered in an accident, it is a single-use item and must be replaced — a used replacement module from a breaker will itself need to come from an undeployed system to be serviceable.

Give the breaker your full registration number and ask them to confirm the donor vehicle's year, body style, trim level, and that the module has not been previously deployed in an accident. You should also ask the breaker to confirm compatibility with your specific SRS system configuration, as pretensioner variants and exact airbag system setups can differ and these details are best verified by the breaker against their stock. Because this is a safety-critical part, do not assume fitment based on year alone — always have it installed and checked by a professional.
