Hyundai Santa Fe Catalytic Converter Replacement Parts

The Santa Fe has run across several distinct generations in the UK — the first-generation (SM, 2001–2006), second-generation (CM, 2006–2012), third-generation (DM, 2012–2018, with a facelift around 2015), and fourth-generation (TM, 2018 onwards) — and catalytic converters are engine- and emissions-era-specific, so crossing a generation boundary is high-risk. The emissions rules changed significantly between Euro 4, Euro 5, and Euro 6, meaning a unit from the wrong era may not only fail to fit but could also cause an MOT failure. Always confirm with the breaker that any used cat matches your exact engine code and registration, not just the generation.

Yes, catalytic converters are fitted to petrol-engined Santa Fe variants and also appear on diesel variants (often as part of a combined cat or close-coupled to the DPF assembly), so most UK Santa Fes will have one. However, the exact configuration — standalone cat, cat-and-DPF combined unit, or separate pre- and post-cat arrangement — varies by engine code and year. Confirm the precise setup on your vehicle with the breaker using your registration before ordering.

Both a 2013 and a 2016 Santa Fe fall within the third-generation DM range (2012–2018), with the facelift arriving around 2015, but sharing a generation does not guarantee the cat will interchange — engine tune, emissions calibration, and exhaust routing can differ across a facelift boundary. Catalytic converter and DPF interchange specifics are strong confirm-with-breaker territory, so match your engine code precisely and have the breaker verify fitment against your registration before you commit.

Trim level — whether your Santa Fe is a base, Premium, Premium SE, or Ultimate — does not affect which catalytic converter is fitted; the cat follows the engine code and emissions standard, not the interior or equipment specification. You may find cosmetic differences in surrounding underbody panels or heat shields depending on the vehicle's history, but the cat itself is the same across trims sharing the same engine. Focus your search on matching the engine code and year rather than the trim name.

No — the 2.2-litre and 2.0-litre diesel Santa Fe engines carry different engine codes and have different exhaust and emissions system configurations, so their catalytic converters are not interchangeable. On diesel models the cat is often integrated with or positioned very close to the DPF, making the exact specification even more important to get right. Always give the breaker your engine code (visible on your V5C or via a registration check) alongside your reg to ensure the correct unit is supplied.

Euro 5 and Euro 6 emissions standards impose different requirements on catalytic converter specification and efficiency thresholds, so fitting a pre-Euro 6 unit to a Euro 6 Santa Fe is likely to cause issues with emissions compliance and could result in an MOT failure at the emissions test. The third-generation DM Santa Fe straddled this transition, so even within the same body generation you need to confirm which emissions standard your specific vehicle was homologated to. Confirm with the breaker that the unit they have matches your registration's exact emissions era before purchasing.
