Second Hand Peugeot 106 Catalytic Converter

Yes, petrol-engined Peugeot 106s are fitted with a catalytic converter as part of the exhaust system, introduced as emissions regulations tightened through the 1990s. The 106 was produced from 1991 to 2003 across two generations, and later petrol variants were built to meet increasingly strict Euro emissions standards requiring a cat. Diesel 106s did not use a catalytic converter in the traditional sense and did not carry a DPF either, so if you have a diesel you are unlikely to need this part.

The Peugeot 106 ran as a first generation from 1991 to 1996 and received a significant facelift and update for the second generation from 1996 onwards, and the exhaust and emissions specifications changed across that boundary. Whether a specific cat from a pre-1996 car will physically fit and comply on a post-1996 car is something you should confirm with the breaker against your exact registration and engine code, as crossing that generation line is strong confirm-with-breaker territory. The engine code on your car is the most important piece of information to give the breaker.

Trim level alone does not affect catalytic converter fitment on the Peugeot 106 — what matters is the engine code and the emissions standard the car was built to, not whether it is badged Zest, Mardi Gras, or Independence. The exception is the GTi, which uses a different, higher-output engine to the rest of the range, so a cat from a standard 1.1 or 1.4 model will not be correct for a GTi even if the cars are the same age. Always quote your engine code to the breaker rather than just the trim name.

Different engine sizes in the 106 range use different exhaust systems sized and calibrated for that engine, so a cat from a 1.4 is not a straightforward swap onto a 1.1 and vice versa. The engine code rather than just the cubic capacity is the reliable guide here, as there were several variants within each size over the production run. Give the breaker your full engine code — found on the engine block or your V5C — to make sure the part matches.

The later second-generation 106s built from the late 1990s into the final 2003 production year were required to meet stricter Euro emissions standards than earlier cars, and a catalytic converter from an earlier second-generation car may not bring a late car back into MOT compliance even if it physically fits. The year of manufacture and the emissions standard your car was originally certified to both matter, not just the generation boundary. Confirm the specific part interchange with the breaker using your registration so they can check the exact spec required.

The most useful information to give a breaker is your full engine code, the year of manufacture, and your vehicle registration, which allows them to check the emissions standard the car was built to. Trim level and colour are not relevant to fitment. Because catalytic converter interchange is closely tied to engine spec and emissions era, breakers will want to verify the part against your specific car rather than just the model name, so having your V5C to hand is helpful.
