Cheap Hyundai i30 DPF

The Hyundai i30 ran as a first generation from 2007 to 2012, then moved to a second generation from 2012 onwards, and the two generations used different engines and exhaust configurations, so a DPF from across that boundary is very unlikely to be a direct swap. Both the engine code and the emissions standard (Euro 4 into Euro 5, then Euro 6) changed across that 2012 cut-off, meaning the mounting, pipework, and sensor positions can all differ. Name the boundary to your breaker and ask them to cross-reference your registration and engine code against the part they have before agreeing to buy.

Yes, the year matters a great deal because DPF design follows the engine code and the emissions standard in force at the time of manufacture — Euro 5 and Euro 6 units are not interchangeable even if they look similar on the outside. A visually alike system from the wrong emissions era can fail to fit correctly and may cause your car to fail its MOT. Always give the breaker your registration number and ask them to confirm the engine code and emissions standard match the part they are quoting you.

The second-generation i30 was facelifted in 2015, so a 2014 car sits in the pre-facelift second-gen run that started in 2012; a 2015 or later car is the facelifted version with potential changes to the engine and exhaust system. Whether a DPF from one side of that 2015 boundary will interchange with the other is strong confirm-with-breaker territory — name the exact build date and engine code to the breaker and ask them to verify the part number matches before purchasing.

For a diesel DPF, trim level — whether your car is an S, SE, Premium, or any other grade — does not affect which DPF fits, because fitment is determined by the engine code and emissions standard rather than the specification of the interior or body kit. The breaker may supply a unit with slight cosmetic differences such as bracket finish or heat-shield colour, but these do not affect function. What you do need to confirm is the engine code and the model year so the breaker can match the correct emissions-era part to your car.

No — DPFs are fitted exclusively to diesel engines, and a petrol i30 does not carry a DPF at all (petrol particulate filters are a separate component found on later GDI petrols). Always confirm with the breaker that the part is sourced from a diesel donor car with a matching engine code to your own.

The engine code tells the breaker exactly which variant of the diesel engine your car runs, which in turn determines the DPF size, mounting points, sensor positions, and the emissions standard the unit was built to meet. Two i30s from adjacent years can carry different engine codes that require different DPF units, even if the cars look identical from the outside. Give the breaker both your registration and the engine code (found on your V5C or stamped on the engine block) to get the most accurate quote and avoid buying a part that will not fit or pass MOT.
