Peugeot 308 DPF Replacement Parts

The 308 Mk1 ran from 2007 to 2013, while the Mk2 arrived in 2013 and received a facelift around 2017, so these are distinct generations with different engines and exhaust configurations. A DPF from a Mk1 is very unlikely to suit a Mk2 due to differences in engine architecture and emissions standards across that boundary. Confirm with the breaker whether the specific part crosses from one generation to the other before buying.

Yes, engine code is the most important thing to match — even within the same generation, the 308 was offered with different 1.6 HDi and 2.0 HDi diesel units carrying different engine codes, and the DPF is matched to a specific engine's exhaust flow and temperature profile. Give the breaker your exact engine code (found on your V5C or inside the engine bay) alongside your registration so they can verify compatibility. Never assume a DPF that physically resembles yours will work correctly.

It matters a great deal — a DPF from the wrong emissions era may not only fail to fit correctly but could cause your car to fail its MOT if the system does not meet the standard the vehicle was originally certified to. The 308 Mk2 spans the Euro 5 to Euro 6 transition, so year of registration and engine code together determine which standard applies to your car. Always confirm the emissions era of any DPF with the breaker against your registration before purchasing.

Trim level — whether Active, Allure, GT Line, or any other — does not affect DPF fitment; the filter is matched to the engine and emissions specification, not the interior or exterior equipment level. You may find cosmetic differences in surrounding exhaust components depending on the exact specification, but the DPF itself is not trim-dependent. What matters is that the engine code and emissions era match, so focus on those details when speaking to the breaker.

The Mk2 308 facelift arrived around 2017 and brought revised engines in some variants, which means a DPF from a pre-facelift Mk2 may or may not cross over to a post-facelift car even within the same generation. The safest approach is to treat the facelift as a potential boundary and confirm with the breaker whether the specific engine code and part number are shared across it. Do not assume compatibility based on year alone within the Mk2 range.

Diesel particulate filters became standard on most new diesel passenger cars in the UK around the time of Euro 5 regulations, which came into effect for new cars from 2011, and the 308 Mk1 diesels registered from that point onward were fitted with a DPF. If your car is a pre-Euro 5 diesel, it may not have been originally fitted with a DPF at all, so confirming your registration against the original specification with the breaker is essential before ordering. Buying a DPF intended for a later, higher-emissions-standard car will not be a straightforward swap onto an earlier vehicle.
