Second Hand Ford S-Max Catalytic Converter

Yes, all petrol-engined Ford S-Max models have a catalytic converter as part of the exhaust system, and diesel models have one too, though on diesels it typically forms part of a combined emissions system that also includes a diesel particulate filter (DPF). The S-Max was sold in the UK from 2006 onwards across two generations, and every variant carried a cat to meet EU emissions legislation. If you drive a diesel S-Max and are unsure whether you need the cat, the DPF, or a combined unit, it is worth confirming the exact assembly with the breaker against your registration number.

The Ford S-Max ran as a first generation from 2006 to 2015 and a second generation from 2015 onwards, and these two generations use different platforms, engines, and exhaust configurations, so a cat from the first generation is very unlikely to be a straight swap onto the second generation. Even where engine codes appear similar across that boundary, the emissions standard changed from Euro 5 to Euro 6 around the 2015 model year, meaning the catalytic converter design and calibration may differ. Always confirm the specific part interchange with the breaker using both registration numbers before committing to a purchase.

Trim level does not affect catalytic converter fitment on the Ford S-Max — what matters is the engine code, fuel type, and the emissions era the vehicle was built to. A Titanium and a Zetec or ST Line with the same engine and the same model year should share the same cat. When buying used you may find minor differences in surrounding heat shields or brackets depending on the vehicle's history, but the core catalytic converter is determined by the drivetrain, not the trim badge.

Diesel S-Max models of this era carry both a catalytic converter and a diesel particulate filter, and the two are separate components, though on some engine configurations they may be housed close together or as a combined assembly. For a 2013 model you are in Euro 5 territory, so you need a part from an equivalent Euro 5 donor vehicle — fitting a part from an earlier Euro 4 car may cause an MOT emissions failure. Because cat and DPF interchange specifics vary significantly by engine code and exact assembly, you should confirm the precise part required with the breaker using your registration number before ordering.

Yes, the engine code is one of the most important details to have to hand when sourcing a used catalytic converter for the S-Max, as Ford used several different petrol and diesel engines across the model's life and each can require a different cat. For diesel models the engine code also determines whether the catalytic function is integrated with the DPF or handled by a separate unit earlier in the exhaust run. Give your engine code and registration to the breaker so they can match the correct part from a suitable donor vehicle rather than relying on year alone.

The first-generation Ford S-Max received a facelift in 2010, and while the overall platform carried over, some engine variants were updated around that period, which can affect exhaust and emissions components. Whether a pre-facelift cat crosses over to a post-facelift car depends on whether the engine code and emissions specification remained identical — this is strong confirm-with-breaker territory rather than something that can be stated as a straightforward yes or no. Ask the breaker to cross-reference both registration numbers to verify the part numbers match before you proceed.
