Used Hyundai i40 DPF

The Hyundai i40 ran from 2011 to 2019 in the UK, with a facelift arriving in 2015, so a 2012 unit comes from the pre-facelift generation and a 2015 unit sits right on that boundary. Both generations used the 1.7 CRDi diesel engine, but whether the DPF housing and connections interchange across that 2015 facelift boundary is something you need to confirm with the breaker against your exact registration and engine code. A pre-facelift DPF may physically resemble the later part but could differ in sensor ports or mounting points.

Trim level does not affect DPF fitment on the i40 — Classic, SE, Sport, and Premium are all cosmetic and equipment-grade distinctions that make no difference to the exhaust or emissions system. The DPF is determined by engine code, model year, and emissions standard, not by what trim badge is on the car. You may find cosmetic differences in the surrounding undertray or heat shielding depending on the car the part is pulled from, but the DPF itself is the same across trims sharing the same engine and year.

The i40 diesel used the 1.7 CRDi engine, but confirm the exact engine code from your V5C or by asking the breaker to check against your registration, as sub-variants can affect which DPF is fitted. Quoting your registration alongside the engine code gives the breaker the best chance of pulling the correct part. Never rely on visual similarity alone, as DPFs from different engine variants or emissions eras can look nearly identical but not interchange correctly.

Euro 5 and Euro 6 DPFs are not interchangeable and you should not attempt to fit one in place of the other — beyond fitment issues, using the wrong emissions-era part could cause your car to fail its MOT. The i40 diesel was primarily a Euro 5 vehicle through most of its UK production run, so confirm with the breaker whether the donor car's registration sits within the Euro 5 or Euro 6 era before agreeing a purchase. Always give the breaker your registration so they can match the emissions standard correctly.

Treating the entire 2011–2019 production span as one interchangeable pool is too broad and risks ending up with a part that doesn't fit or fails MOT. The 2015 facelift is a known boundary point, and whether a DPF from one side of that date fits the other is something you must confirm with the breaker against your registration and engine code. Wide-ranging listings are common on used-parts sites but are not a guarantee of fitment across generation or emissions-standard boundaries.
