Second Hand Peugeot 408 DPF

The Peugeot 408 was sold in the UK from around 2010 to 2014, making it a single-generation model with no full generational replacement in that period. DPF fitment is driven by engine code and emissions standard rather than model year alone, so a 2010 car and a 2013 car could share a DPF if they share the same engine code and Euro emissions tier, or could differ if one predates a calibration or specification change. Always confirm the exact engine code from your V5C or the plate under the bonnet before sourcing a unit from a breaker.

Both years sit within the same single UK-generation 408 and both are likely to be Euro 5 diesel units, so on paper they may be compatible if the engine codes match. However, whether the specific DPF from a 2011 car physically interchanges with a 2013 car is strong confirm-with-breaker territory — give the breaker both registration numbers so they can cross-reference part numbers before you commit. Never assume fitment on year alone.

Trim level does not affect DPF fitment on the 408 — Active, Allure, and SR all use the same engine and exhaust configurations for a given engine code, so the DPF is determined by the engine, not the badge. You may find minor cosmetic differences in surrounding heatshields or brackets depending on what else was fitted to the donor car, but the core filter unit itself is trim-agnostic. Confirm the engine code matches and let the breaker verify the part number rather than worrying about which trim the donor car was.

No — petrol and diesel particulate filters are entirely different components designed for different combustion by-products, and they are not interchangeable. The 408's diesel engines are the ones that carry a conventional DPF as standard; petrol variants use a different aftertreatment setup if equipped at all. Always make sure the donor car is the same fuel type as yours before agreeing a price with a breaker.

The 408 shares its platform and engine family with other PSA models of the period, so there is a chance of parts commonality, but whether a specific DPF from a 308 or 508 physically interchanges with the 408 is exactly the kind of cross-model fitment question you need to route to the breaker. Give them your 408's registration and engine code alongside the details of the donor vehicle, and ask them to match part numbers before you pay. A visually similar unit from the wrong application could fail to seal correctly or cause an MOT failure.

A used DPF can be a cost-effective solution, but the condition of the filter matters as much as fitment — a heavily blocked or cracked unit from a high-mileage donor car may not regenerate properly and could cause an immediate advisory or failure at MOT. Ask the breaker what mileage the donor car had and whether the DPF warning light was active, and ideally request that they inspect it before dispatch. Correct fitment for your engine code is the first hurdle, but condition is the second, equally important one.
