Used Ford Focus DPF

The Focus Mk3 ran from 2011 to 2018 with a facelift in 2014, so a 2013 car is pre-facelift and a 2015 is post-facelift; the facelift can coincide with changes to engine specifications and emissions calibration that affect DPF compatibility. Whether a specific DPF crosses that 2014 boundary and fits correctly is strong confirm-with-breaker territory — give the breaker both registration numbers so they can check engine codes and emissions specs against each other. Never assume a part fits just because both cars share the Mk3 name.

Trim level — Zetec, Titanium, ST-Line, or any other — does not affect DPF fitment; what matters is that both cars share the same engine code and fall within the same emissions era. You may find minor cosmetic differences in surrounding heat shields or brackets depending on the exact build, but the DPF itself is matched to the engine and exhaust specification, not the trim badge. Confirm the engine code with the breaker against your registration to be sure.

The DPF is calibrated to the specific engine it was designed for, so matching the engine code is essential — common diesel engines in the Focus include the 1.5 TDCi and 2.0 TDCi families, each with distinct codes that can vary across model years. An incorrect engine code can mean the DPF physically won't mount correctly, or that the back-pressure characteristics are wrong, potentially causing warning lights or an MOT failure. Pull your engine code from the V5C or have a breaker run your registration before ordering.

Yes — Euro 5 and Euro 6 DPFs are not interchangeable because Euro 6 units are designed to meet stricter particulate filtration standards, and fitting the wrong emissions-era part could cause your car to fail its MOT emissions test. The Focus moved to Euro 6 compliance around 2015 onwards, so the year of the donor car matters as much as the engine code. Always confirm the emissions standard of any used DPF with the breaker against your exact registration.

The Focus Mk2 ran from 2004 to 2011 and the Mk3 from 2011 to 2018, and these generations used different engine families with different exhaust architectures, making a Mk2-to-Mk3 DPF swap very unlikely to work. Beyond the physical fitment issues, the emissions eras are different, which adds a further MOT risk. Confirm with a breaker using both registrations — they will be able to check part numbers and rule out any crossover quickly.

In most cases the DPF is determined by the engine and emissions specification rather than the body style, so a DPF from a Focus hatchback and a Focus estate with the same engine code and emissions era should be the same unit. However, exhaust routing and surrounding components can occasionally differ between body styles, so it is worth mentioning your body style to the breaker when you request a quote. Confirm fitment with the breaker against your registration before purchasing.
