Hyundai i30 Throttle Body Replacement Parts

Yes, petrol variants of the Hyundai i30 have a throttle body, but diesel variants do not — diesel engines control fuelling differently and use no throttle body in the conventional sense. If you have a diesel i30 and are chasing an air or fuelling fault, you may be looking for an EGR valve, swirl flap motor, or inlet manifold instead. Check your V5 or run a VIN check to confirm your fuel type before ordering.

These sit either side of a significant model change: the first-generation i30 (Mk1) ran from 2007 to 2012, while the second-generation i30 (Mk2) launched in 2012 and received a facelift around 2015, so a 2010 part and a 2014 part are from entirely different generations with different engine families. Fitment across that Mk1-to-Mk2 boundary is very unlikely, and engine codes will differ even for nominally similar displacements. Supply your engine code — found on your V5 or via a VIN check — to the breaker so they can match the correct unit.

Trim level does not determine which throttle body fits — what matters is the engine code, not whether the car is a Classic, Active, Style, SR, or Premium. Two i30s with identical engine codes will use the same throttle body regardless of trim. Bear in mind that cars from higher trims may have had additional ancillary brackets or wiring routed differently, but the core throttle body unit itself follows the engine, not the badge.

Yes, engine displacement and crucially the engine code are the most important details to get right — a 1.4 petrol and a 1.6 petrol i30 will use different throttle bodies and the two are not interchangeable. The engine code is stamped on the engine block and also appears on your V5 logbook; always pass this to the breaker rather than relying on displacement alone. Matching on engine code gives you the best chance of a correctly sized and mapped unit.

The Mk2 i30 ran from 2012 through to around 2017, with a facelift arriving approximately 2015, and it is possible that ancillary fittings or sensor configurations changed at that mid-production point. The engine code remains your primary guide — if the donor car shares your exact engine code, that is a strong indicator of compatibility. However, whether specific mounting or connector details changed across the facelift is something you should confirm with the breaker against your registration, as mid-production running changes are not always publicly documented.

Some modern petrol engines do require the ECU to relearn or adapt to a replacement throttle body, and in certain cases there may be immobiliser or coding considerations depending on the unit. Whether your specific i30 engine requires this procedure is something to confirm with your fitting garage before purchase, as it can affect which used units are suitable. This is not something a breaker can guarantee either way, so raise it with a mechanic familiar with Hyundai systems.
