Used Peugeot Expert Differential

The Peugeot Expert ran as the second generation (Mk2) from 2007 through to 2016, so both years sit within the same generation and a differential from that era is worth investigating. Fitment depends primarily on matching the engine code — found on your V5 or via a VIN check — and ensuring the gearbox type matches, as manual and automatic units differ. Ask the breaker to cross-reference your engine code and gearbox type against the donor vehicle before buying, as ancillary or ratio changes can occur mid-production without a visible model change.

No — the third-generation Expert (Mk3) launched in 2016, so a 2017 or 2018 unit comes from a different generation to a 2015 Mk2 vehicle. The Mk3 is a substantially redesigned platform shared with the Citroën Dispatch and Toyota ProAce of the same era, making cross-generation fitment unlikely. Confirm this boundary firmly with the breaker by supplying both registrations and engine codes, as they can check whether any carry-over parts exist.

Trim level does not affect differential fitment on the Peugeot Expert; the differential is determined by the engine code, fuel type, and gearbox type, not by whether the van is badged as an entry-level or top-spec Asphalt or Sport. You may find cosmetic or interior differences between trims on a donor vehicle, but those have no bearing on whether the mechanical differential unit will suit your van. Give the breaker your engine code and gearbox type rather than your trim name.

Yes, engine code matters above everything else for the differential, because different diesel units — for example across the BlueHDi family on the Mk3 — can use different final drive ratios or housing configurations. The engine code is stamped on the engine block and is also shown on your V5 logbook or through a HPI/VIN check. Always give the breaker your exact engine code so they can match the donor vehicle correctly rather than relying on year or badge alone.

The third-generation Expert (2016 onwards) shares its platform with the Citroën Dispatch and Toyota ProAce of the same generation, so there is a reasonable chance of parts commonality. However, whether a specific differential unit interchanges correctly depends on matching engine codes, gearbox types, and any variant differences between the three brands. Route this question to the breaker with both registrations and engine codes, as they will be able to confirm compatibility against the donor part.
