Cheap Hyundai Tucson Catalytic Converter

The Tucson sold in the UK across this period is broadly the same second-generation model (2010–2015), so there is some overlap in engine families, but the key variable is the engine code and emissions standard — Euro 5 rules tightened during this window and the catalyst specification can differ accordingly. A unit from the same engine code and the same emissions era is your starting point, but catalytic converter interchange is strong confirm-with-breaker territory, so share your registration with the breaker so they can verify against their part before you commit.

The second-generation Tucson ran from 2010 to 2015 with a facelift arriving around 2013, and while the core engine codes carried over, emissions calibration and exhaust system specifications can vary across that boundary. Because catalytic converter interchange across a facelift line is genuinely uncertain, you should treat this as confirm-with-breaker territory and give the breaker your exact registration so they can check the engine code and emissions spec on their unit against yours.

All petrol Tucson variants have a catalytic converter as part of the exhaust after-treatment system, and diesel variants have a catalytic converter too — typically combined with or positioned alongside a diesel particulate filter (DPF) rather than instead of one. If your Tucson is diesel and the fault or MOT failure points to particulate filtration rather than catalyst function, confirm with the breaker whether you need the cat, the DPF, or a combined unit, as these can be packaged differently depending on the engine and year.

Trim level — whether that is S, SE, Sport, or Premium — does not affect catalytic converter fitment on the Tucson; the exhaust system follows the engine code, fuel type, and emissions standard, not the interior or equipment specification. What matters is matching the engine code and Euro emissions era, so focus on those details rather than the trim name when sourcing a used unit from a breaker.

The second-generation Tucson (2010–2015) and the third-generation model (2015 onwards) are significantly different vehicles with different engine families and updated emissions requirements moving further into Euro 6 territory, so these are not considered interchangeable generations. Fitting a cat from the wrong generation risks both a non-fit and an MOT failure if the emissions spec does not match, so confirm with the breaker against your registration before purchasing any unit.

Engine displacement alone is not enough to confirm fitment — you need the specific engine code (for example D4EA or its successors) and the emissions standard (Euro 5 versus Euro 6) to match correctly, as the catalyst specification is tied to those details rather than just the 2.0 badge. Diesel Tucsons also typically have a DPF alongside the catalytic converter, and these components can be packaged together or separately depending on year, so give your registration to the breaker and let them cross-reference the engine code and emissions era on their unit before agreeing a sale.
