Second Hand Hyundai i30 Air Flow Meter

It depends on the engine. Petrol i30s generally do use a mass air flow (MAF) sensor, while diesel variants typically rely on a different air metering strategy and may not use a conventional air flow meter in the same way. If you have a diesel i30, confirm with the breaker whether an air flow meter is the correct part you need, as you may actually be looking for a different sensor such as a MAP sensor. Checking your engine code on your V5 or via a VIN check before contacting breakers will save time.

Almost certainly not — the first-generation i30 ran from 2007 to 2012, while the second generation (GD) launched in 2012, so these are entirely different platforms with different engine families. Even if both cars share a similar engine displacement, the engine codes differ between generations and the air flow meter is matched to the engine code, not the badge. You need to source a part from the correct generation, and you should confirm the exact engine code with the breaker to be sure.

No — trim level does not affect air flow meter fitment on the i30. The air flow meter follows the engine code, not the trim badge, so a Classic and a Premium with the same engine code will use the same unit. The only thing worth noting is that cosmetic differences between trim levels (such as body kit panels) are irrelevant to a mechanical part like this. Focus your conversation with the breaker on your engine code and model year rather than your trim name.

Yes, year within a generation can matter because manufacturers sometimes make running production changes that affect sensors like the air flow meter. The GD-generation i30 ran from 2012 through to around 2017, and there were mid-cycle updates during that period. While many parts interchange freely within a generation on the same engine code, you should confirm with the breaker whether the specific year of the donor vehicle is a close enough match to yours, particularly if the part sits close to any production change point.

In most cases the gearbox type does not directly affect the air flow meter itself, as the sensor is part of the intake system and is determined by the engine rather than the transmission. However, automatic variants can sometimes have different ECU calibrations or wiring configurations, so it is worth flagging your gearbox type to the breaker when you enquire. Confirm compatibility against your registration before purchasing to be safe.

No — the third-generation i30 (PD platform, launched 2017) uses a new engine family compared to the second-generation GD cars, and the air flow meter will not be a straightforward swap across that generational boundary. Even turbocharged petrol variants like the 1.4 T-GDI in the third generation have different engine codes to their predecessors. Always give the breaker your exact engine code from your V5 or a VIN check, and do not assume cross-generation compatibility.
