Used Mercedes-Benz X-Class DPF

The X-Class was sold in the UK exclusively as a diesel, so all variants carry a DPF; the key fitment detail is the engine code, with the X 220 d using a 2.3-litre unit and the X 250 d and X 350 d using different outputs of a 3.0-litre V6, meaning the DPF from one engine family will not simply swap to another. Always confirm the exact engine code from your V5C or via an HPI check and pass it to the breaker before ordering.

No, trim level does not affect DPF fitment on the X-Class — Pure, Progressive, and Power trims share the same exhaust and emissions hardware for a given engine code, so a DPF from a base Pure model and a top-spec Power model with the same engine will be the same part. You may notice minor cosmetic differences around the exhaust tips or underbody covers when comparing trim levels, but these do not affect whether the DPF itself fits or functions.

The Mercedes-Benz X-Class was produced from 2017 to 2020, a relatively short and single-generation run, but you should still confirm the exact engine code of the donor vehicle matches yours because different power variants used different exhaust systems throughout the production life. Confirm the full engine code and registration year with the breaker to make sure the unit came from a like-for-like vehicle.

The X-Class had a single generation with no major facelift that is well-established as changing the emissions hardware, but because DPF and catalytic converter interchange specifics are strong confirm-with-breaker territory, you should not assume a unit from an early 2017–2018 car will be a straight swap onto a 2019–2020 car without checking. Give the breaker both registration numbers and engine codes and let them verify compatibility before purchasing.

In principle, Euro 5 and Euro 6 emissions standards apply across EU markets, so the emissions era is what matters rather than the country of sale, but subtle differences in exhaust routing or sensor positions can exist between vehicles built for different markets. To be safe, confirm with the breaker that the donor vehicle was right-hand drive and matched to the UK specification for your engine code, as a visually similar DPF from the wrong configuration may not fit correctly or could cause issues at MOT.

The X-Class was based on the Nissan Navara NP300 platform and shares significant mechanical architecture with the Navara and the Renault Alaskan, which means there is a possibility of parts crossover, but DPF and catalytic converter interchange across different manufacturers is firmly in confirm-with-breaker territory and should never be assumed. Provide your registration and engine code to a breaker who can check part numbers across all three vehicles before committing to a purchase.
