Second Hand Nissan Pathfinder Catalytic Converter

Yes, all petrol-engined Pathfinders sold in the UK have a catalytic converter as standard, and diesel variants from later generations also carry a diesel oxidation catalyst (DOC) as part of their emissions system. The R51 generation (2005–2013) sold here was predominantly the 2.5 dCi diesel, which uses a diesel oxidation catalyst rather than a traditional three-way petite catalytic converter, while any petrol variants carry a conventional cat. Confirm which engine you have before searching, as the parts differ significantly.

Both years sit within the R51 generation (2005–2013), so the generation boundary is not the issue here, but the emissions era may be, as Euro 4 and Euro 5 rules changed during this period and the exhaust system components can differ accordingly. If both vehicles share the same engine code — most commonly the YD25DDTi 2.5 dCi diesel — fitment is more likely, but catalytic converter and diesel oxidation catalyst interchange specifics are strong confirm-with-breaker territory, so quote your registration and the donor vehicle's registration to the breaker before purchasing.

No — trim levels such as S, SE, SVE, and Aventura do not affect the catalytic converter, as the exhaust system follows the engine code and emissions specification rather than the trim. You may find cosmetic differences around the exhaust tips or undertrays between trims, but the cat or diesel oxidation catalyst itself is determined by engine and emissions era. Focus on matching engine code and year rather than trim when searching.

The R51 Pathfinder received a facelift around 2010, and while the core engine code remained the YD25DDTi for the diesel, there were updates to emissions equipment across the production run that may affect whether exhaust components interchange directly. This is firmly confirm-with-breaker territory — name the facelift boundary to your breaker and provide both vehicles' registrations so they can cross-reference the exact part numbers before supplying.

The R50 (1997–2004) and R51 (2005–2013) are entirely different generations with different engines, different exhaust architectures, and different emissions standards, so their catalytic converters and diesel oxidation catalysts are not interchangeable. The R50 sold in the UK used a 3.3-litre V6 petrol with a conventional three-way catalytic converter, whereas the R51 was predominantly the 2.5 dCi diesel with a different system entirely. Always search by generation and engine code, and confirm with the breaker against your registration.

The key factors are matching the engine code and ensuring the donor part comes from a vehicle of the same or compatible emissions era, as fitting a unit from the wrong era can cause an MOT emissions failure even if it physically bolts on. For the R51 diesel, the diesel oxidation catalyst condition is assessed as part of the emissions test, so ask the breaker about the age and condition of the unit, not just that it fits. Confirm all specifics against your registration with the breaker, as interchange details for catalytic converters and DOCs are model-specific and should never be assumed.
