Fiat 500 Differential Replacement Parts

The Fiat 500 (second generation) ran from 2007 through to the end of production, with a facelift arriving in 2015, so a 2012 donor and a 2016 car sit either side of that facelift boundary. The differential that fits depends primarily on your engine code rather than the year alone, so match the engine codes between donor and recipient first. Whether ancillary or mounting details changed across the 2015 facelift is something you should confirm with the breaker against your registration before buying.

Engine code matters above everything else for a mechanical part like a differential — the same model year can have several different engine options, each potentially using a different drivetrain configuration. Your engine code is printed on your V5C and can also be retrieved via a VIN check; supply it to the breaker rather than relying on the year alone. Fuel type and gearbox type (manual or automated/Dualogic) are the next most important details to confirm.

Trim level alone does not affect differential fitment — what matters is the engine code, fuel type, and gearbox type fitted to each car. However, Abarth models use performance-tuned engines with different codes from standard 500 units, so in practice the drivetrains are different and the differentials are very unlikely to interchange. Always match engine codes between the donor Abarth and your vehicle, and confirm suitability with the breaker against your exact registration.

Yes, gearbox type is a critical fitment factor — the differential on a Dualogic-equipped car is integral to a different transmission assembly compared with a manual, and the two are not interchangeable. Always tell the breaker which gearbox type your car has, alongside the engine code, to make sure the correct unit is quoted. Fitting a differential from the wrong gearbox type will not work.

No — the petrol and diesel Fiat 500 use different engines with different codes, and the drivetrain components including the differential are not shared between the two fuel types. Confirm your fuel type and engine code with the breaker so they can source the correct donor car. Mixing petrol and diesel drivetrain parts is not compatible and should not be attempted.

Year alone is not sufficient because the Fiat 500 was offered with multiple engine options across every year of production, each with a different engine code that can affect drivetrain compatibility. Ask the seller to check the engine code on the donor vehicle — it will be stamped on the engine block and may also appear on any paperwork — and match it to the code shown on your V5C. If the engine code cannot be confirmed, ask the breaker to cross-reference it against your registration plate before you commit to a purchase.
