Hyundai i40 Body Control Module Replacement Parts

Yes, the Hyundai i40 is fitted with a Body Control Module (BCM), which manages a range of electrical functions including lighting, central locking, and the windows. It is present across the i40 range, covering both the saloon and estate (Tourer) body styles. If you are searching for a used unit, make sure to quote your registration to the breaker so they can match the correct part.

The Hyundai i40 was produced as a single generation running from 2011 to 2019, with a facelift introduced in 2015. A BCM from a pre-facelift car (2011–2014) crossing into a facelift car (2015–2019) is a boundary you should treat with caution, as software calibration and wiring configurations may differ. Confirm with the breaker against your registration before purchasing.

The i40 was sold in the UK in trim levels including Classic, Active, SE, Style, and Premium, but trim level alone does not determine BCM compatibility in the way that generation or facelift status does. That said, higher trims may have additional features such as heated seats or more complex lighting that are configured within the BCM, so a unit from a lower-spec car may not support all functions on a higher-spec one. Always confirm the donor car's trim and specification with the breaker alongside your registration to ensure the replacement unit covers everything your car needs.

The i40 was offered in both saloon and estate (Tourer) body styles, and the BCM may be configured differently between them due to differences in rear wiper controls, boot lighting, and other body-specific functions. It is worth telling the breaker which body style your car is, as well as providing your registration, so they can source a unit from a matching or confirmed-compatible vehicle. Do not assume a saloon BCM will be a straight swap into an estate without checking.

For most of the BCM's core functions – lighting, locking, and body electrics – the engine variant is unlikely to be the primary compatibility factor. However, certain engine-related options such as start-stop systems fitted to some diesel variants may be integrated into or communicate closely with the BCM, so it is sensible to tell the breaker whether your car is petrol or diesel and whether it has start-stop. Confirm fitment against your registration rather than assuming any i40 BCM will be interchangeable across all engine options.

Used BCMs very commonly require programming or coding to the recipient vehicle, and a second-hand unit from a breaker is unlikely to work correctly as a straight plug-in replacement without this step. You will typically need a Hyundai-compatible diagnostic tool – either at a dealership or a specialist independent – to marry the unit to your car's VIN and immobiliser. Factor in the cost of coding when budgeting for this repair, and ask the breaker whether the unit comes with any history or mileage information to help with the process.
