Second Hand Peugeot 306 DPF

The engine code is the most important thing to match for a DPF on the 306 — give the breaker your exact code, which you'll find on your V5C or stamped on the engine block. Different engine codes can use different exhaust and emissions configurations even within the same model year, so a visual match alone isn't enough. Always confirm the engine code with the breaker against your registration before buying.

The Peugeot 306 ran from 1993 to 2002, which predates the widespread adoption of diesel particulate filters — DPFs became common on European diesel cars from around 2004 onwards as part of Euro 4 and Euro 5 compliance. If your 306 has something described as a DPF, it is likely an aftermarket addition or a misidentification of another exhaust component such as a catalytic converter. Confirm exactly what component you need with a breaker or mechanic before ordering, as you may actually be looking for a different part.

The 306 received a significant facelift in 1997, with the updated model running through to the end of production in 2002, while the pre-facelift cars cover 1993 to 1997. Because the 306 predates factory DPF fitment entirely, any DPF-related fitment question spanning that boundary is really a question about aftermarket parts or a misidentified component, and the answer will depend entirely on your specific engine code and exhaust configuration. Confirm the exact part and its compatibility with the breaker against your registration.

Trim level — whether that's L, LX, XL, XSi, or any other 306 variant — does not affect DPF fitment, as exhaust and emissions components follow the engine code and fuel type, not the trim. You may find cosmetic differences in how surrounding exhaust components look depending on the car's original spec, but the core fitment question comes down to matching the engine code. Confirm the exact part needed with the breaker against your registration.

Peugeot did share engines across its range, so it is possible that some exhaust components crossed over between models like the 206, 306, and 406 — but whether a specific DPF or similar component from another model will physically fit and pass MOT on your 306 is strong confirm-with-breaker territory. The breaker will need your engine code and registration to check compatibility properly. Never assume a part will fit based on shared brand or similar engine family alone.
