Hyundai i40 Throttle Body Replacement Parts

It depends on the engine variant. The i40's petrol engines — including the 1.6 GDi and 2.0 GDi — do use a throttle body, so if you're running a petrol i40 you'll find one on the car. The i40's diesel engines (1.6 CRDi and 1.7 CRDi) use a different fuelling system and do not have a conventional throttle body in the same way, so diesel owners searching for one are likely looking for something else, such as a swirl flap assembly or EGR valve — confirm with a breaker what you actually need.

The Hyundai i40 was produced as a single generation running from 2011 to 2019, with a facelift arriving around 2015, so a 2012 car is pre-facelift and a 2015 car sits at or around that boundary. The most reliable way to confirm whether the two are interchangeable is to match the engine code from your V5 or a VIN check against the donor car's engine code — if the codes match on both petrol units, fitment is much more likely. Whether any ancillary or mounting changes were made around the 2015 facelift is something you should confirm with the breaker against your registration before buying.

Trim level does not affect throttle body fitment on the i40 — the part follows the engine, not the badge. A 1.6 GDi in a base Classic and a 1.6 GDi in a top-spec Premium SE will use the same throttle body, so you don't need to worry about sourcing a trim-matched unit. Do be aware that your registration and engine code are still the details to give the breaker, as they identify the correct part far more reliably than trim name alone.

No — body style has no bearing on throttle body fitment whatsoever. The throttle body is determined entirely by the engine fitted to the car, so a 2.0 GDi saloon and a 2.0 GDi estate use the same unit. Give the breaker your engine code and registration and they'll be able to match the part correctly regardless of which body style you drive.

Some modern throttle bodies require calibration or adaptation via diagnostic equipment after fitting, and there is a possibility that ECU pairing or immobiliser coding could be a factor on certain i40 variants. This is not something we can confirm or rule out as fact for every engine and build date, so you should raise it directly with the breaker and with whoever is carrying out the fitting before you commit to buying a used unit.

The single most useful piece of information is your engine code, which you can find on your V5 logbook or by running a VIN check — this tells the breaker exactly which variant of the 1.6 GDi or 2.0 GDi petrol engine you have, which is what determines the correct throttle body. Also give them your registration, model year, and confirm you have a petrol i40, since diesel variants do not use a conventional throttle body. The more detail you provide upfront, the more accurately a breaker can match the part and advise on fitment.
