Used Peugeot 5008 Catalytic Converter

Yes, catalytic converters are fitted to petrol-engined Peugeot 5008s across both generations (first generation 2009–2017, second generation 2017 onwards). Diesel 5008s use a different emissions system centred on a diesel particulate filter (DPF) and a diesel oxidation catalyst (DOC), so if your 5008 is diesel you are unlikely to be looking for a traditional catalytic converter in the petrol sense — confirm with the breaker exactly which component you need and quote your registration. Petrol owners searching for a cat are in the right place, but always confirm the engine code with the breaker before ordering.

The first-generation 5008 ran from 2009 to 2017 and the second generation from 2017 onwards, and these are fundamentally different platforms with different engines and exhaust layouts, so a direct swap across that boundary is very unlikely. Beyond the physical differences, emissions legislation tightened between those eras (Euro 5 to Euro 6), meaning a cat from the wrong generation could cause an MOT emissions failure even if it could be made to bolt on. Always confirm interchange specifics with the breaker against your registration before buying.

Trim level — whether Active, Allure, GT-Line, or any other — does not affect catalytic converter fitment on the 5008; what matters is the engine code, fuel type, and the emissions standard the car was built to. You may find cosmetic differences around the exhaust exit (e.g. finisher style) between trims, but the cat itself is determined by the engine and emissions era, not the trim badge. Confirm your engine code with the breaker and they can match the correct unit.

The year matters because it determines which emissions standard applies — the 5008 first generation spans both Euro 5 and earlier Euro 6 introductions, and fitting a cat from the wrong emissions era can cause the car to fail its MOT on emissions even if the part physically fits. Engine code is the most reliable matching point, as Peugeot used different petrol units across the production run. Confirm the exact engine code and registration with the breaker rather than matching by year alone, as this is strong confirm-with-breaker territory.

The 5008 shares platform and engine families with other PSA Group models including the 3008 and 308, so there is a possibility of parts compatibility where the same engine code is used across models. However, catalytic converter and exhaust system interchange across different model lines is a detail that must be confirmed with the breaker against your specific engine code and registration — do not assume compatibility based on shared engines alone, as pipe routing, mounting points, and heat shielding can differ. A good breaker will be able to check this for you.

On diesel Peugeot 5008s, a DPF (diesel particulate filter) warning light points to the particulate filter, not a traditional catalytic converter — these are separate components and you would need to search specifically for a DPF or diesel oxidation catalyst (DOC) depending on what has failed. On petrol 5008s, a catalytic converter fault is more likely to show as an engine management or emissions warning rather than a dedicated DPF light, since petrol variants do not have a DPF. Confirm with the breaker exactly which component applies to your fuel type and engine code before ordering anything.
