Used Fiat Fullback Catalytic Converter

Yes, the Fiat Fullback does have a catalytic converter — it was sold in the UK with a 2.4-litre diesel engine, and like all diesel vehicles of its era it uses both a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF) as part of its exhaust aftertreatment system. When customers refer to the catalytic converter on a diesel Fullback, they are typically referring to the DOC element of this combined system. If you are unsure which component has failed, confirm with your breaker exactly which part of the system you need before ordering.

The Fiat Fullback was sold in the UK from around 2016 onwards and had a fairly short and consistent production run, with one engine variant — the 2.4-litre diesel — available throughout, which limits but does not eliminate variation in exhaust aftertreatment components. Even within a single engine family, the specific calibration and configuration of the DOC and DPF can vary by build date and emissions compliance level, so a unit from a different year may not be a straightforward swap. Always confirm interchange compatibility with your breaker using your exact registration number before purchasing.

No, trim level does not affect which catalytic converter or diesel oxidation catalyst your Fullback needs — fitment is determined by the engine and the emissions specification, not by whether your truck is in standard or higher specification trim. The Fullback was offered in trims including LX and LX Plus in the UK market, but these differences are cosmetic and equipment-related rather than mechanical. Confirm the part against your registration and engine code with the breaker, not your trim badge.

The Fiat Fullback is mechanically derived from the Mitsubishi L200 and shares significant underpinnings, so there is a reasonable possibility of parts commonality in the exhaust system. However, whether the diesel oxidation catalyst or DPF from a specific L200 build year and specification will interchange correctly with your Fullback is something you must confirm directly with the breaker against both registration numbers, as calibration and fitment details can differ even between closely related vehicles. Do not assume compatibility without that check.

The gearbox type — manual or automatic — does not affect which catalytic converter or diesel oxidation catalyst is fitted to the Fullback, as the exhaust aftertreatment system is determined by the engine and emissions specification rather than the transmission. You do not need to match the gearbox when sourcing this part. Confirm the part against your engine code and registration with the breaker to make sure you are getting the correct emissions-era component.

A used diesel oxidation catalyst or DPF from the correct specification Fullback can pass an MOT provided it is in good working condition and correctly matched to your vehicle's emissions requirements. Fitting a unit from the wrong emissions era or specification could result in an MOT failure, even if it physically bolts on. Confirm with your breaker that the part matches your registration and engine code, and have the system checked by a qualified mechanic after fitting.
