Hyundai i40 Engine Replacement Parts

The i40 was sold as a single generation running from 2011 to 2019, with a facelift arriving in 2015, so a 2012 donor and a 2015 recipient sit either side of that facelift boundary. The engine code is the critical check here — if the codes match, the mechanical unit itself is likely compatible, but ancillary components, brackets, and mountings may have changed across the facelift, so confirm the exact specification with the breaker against your registration before buying.

The 1.7 CRDi diesel is the most common i40 engine in the UK and all examples share the D4FD engine code, which is the primary fitment indicator — if the codes match, the core engine is the same regardless of the year on the V5. That said, confirm with the breaker that ancillary items such as the EGR, turbo pipework, and engine management loom are identical to your car, as these can vary across the production run.

For the i40, trim levels such as Classic, Active, Style, and Premium are specification grades rather than mechanical variants, so the trim name has no bearing on engine fitment whatsoever. What determines fitment is the engine code, fuel type, and gearbox type (manual or automatic), not what badge is on the dashboard — though bear in mind a donor car from a different trim may come with different ancillary components or interior parts you would not need.

The two engines you are most likely to encounter in UK i40s are the 1.7 CRDi diesel coded D4FD and the 1.6 GDI petrol coded G4FD; quoting your code to the breaker is far more useful than quoting the year or trim alone. You can find your engine code on your V5C logbook or by running a VIN check, and supplying it upfront will save time and reduce the chance of ordering the wrong unit.

The i40 facelift arrived in 2015 and while the engines themselves carried the same codes across the pre- and post-facelift cars, whether a unit from a pre-2015 car drops cleanly into a post-2015 car depends on whether any mounting points, ancillaries, or engine management wiring changed at that point. Name the facelift year and your registration to the breaker and ask them to confirm compatibility specifically, as this is not something that can be guaranteed without checking the donor and recipient cars against each other.

The engine block itself may share the same code whether it came from an automatic or manual i40, but the gearbox type affects which ancillaries, flywheel, and potentially which ECU came with the car, so mixing configurations is not straightforward. You should tell the breaker both your engine code and your gearbox type so they can source a unit that matches your drivetrain, and be aware that ECU pairing and immobiliser coding are matters you will need to confirm with the breaker or a specialist for your specific vehicle.
