Hyundai i40 Differential Replacement Parts

The Hyundai i40 was sold in the UK from 2011 to 2019 as a single generation, with a facelift introduced in 2015 that brought styling and trim updates. For the differential, the engine code and gearbox type matter far more than whether the car is pre- or post-facelift. That said, if you are looking at a differential that crosses the 2015 facelift boundary, confirm with the breaker against your registration that no ancillary or mounting changes affect your specific application. Supplying your engine code from the V5 or a VIN check gives the breaker the most reliable basis for matching the part.

A 2013 i40 is pre-facelift and a 2016 is post-facelift, so you are crossing the 2015 boundary, which means you should not assume straightforward interchangeability. The key factors are whether both cars share the same engine code and the same gearbox type — manual or automatic — rather than the model year alone. Confirm with the breaker against both registrations whether any mounting or ancillary differences apply across that boundary. Never assume fitment based on year alone with this kind of cross-facelift swap.

Trim level does not affect differential fitment on the i40; SE, Premium, and Style are cosmetic and equipment grades rather than mechanical variants. What drives compatibility is the engine code, fuel type, and whether the car has a manual or automatic gearbox. You may find minor cosmetic differences between donor and recipient cars such as different interior or exterior finishes, but these are irrelevant to the differential itself. Focus on matching the engine code and gearbox type and confirm the details with the breaker against your registration.

Yes — the i40 was available with a 1.6 petrol, a 1.7 CRDi diesel, and a 2.0 petrol, and these can have different differential specifications to suit their outputs. The engine code printed on your V5 or obtainable via a VIN check is the single most useful detail you can give a breaker when sourcing this part. Gearbox type — manual or automatic — also matters and should be confirmed at the same time. Always supply both the engine code and gearbox type rather than just the engine size, as codes distinguish variants the badge alone does not.

No — automatic and manual differentials are not interchangeable on the i40 because they are matched to fundamentally different drivetrain configurations. Even where the engine code is identical, the internal ratios and output flanges differ between transmission types. Make sure you tell the breaker clearly whether your car is manual or automatic when requesting a quote. Supplying your registration alongside the engine code from the V5 gives the breaker the best chance of identifying the correct unit.

A higher-mileage donor differential is not necessarily unsuitable, as differentials on well-maintained i40s can cover very high mileages without internal failure, but it is worth asking the breaker about the donor vehicle's service history and the condition noted on removal. More important for fitment is that the engine code and gearbox type match your car exactly. Reputable breakers on Findapart will often provide a short warranty on the part, so it is worth asking about that when you receive your quotes. Confirm all mechanical details with the breaker against your registration before purchasing.
