Second Hand Fiat 500 Engine

Both years fall within the same second-generation Fiat 500, which ran from 2007 onwards with a facelift in 2015, so on paper the engine family is closely related. However, the 2015 facelift brought changes to some ancillaries and engine management that may affect a straight swap, so you should confirm with the breaker whether their unit matches your exact engine code before buying. The engine code is printed on your V5C or available via a VIN check, and it is the single most reliable detail you can give the breaker.

Trim level — whether Pop, Lounge, Sport or any other — does not affect engine fitment on the Fiat 500; the engine follows the engine code, not the badge on the tailgate. A Pop and a Lounge built in the same year with the same engine code will use mechanically interchangeable units. Just be aware you may receive an engine with slightly different dress ancillaries depending on spec, so confirm the exact code with the breaker against your registration.

No — the TwinAir is a 0.9-litre two-cylinder turbocharged unit with its own distinct engine code, while the 1.2 is a naturally aspirated four-cylinder with a different code entirely. These engines are not interchangeable, and you must tell the breaker which engine code your car carries to ensure you receive the correct unit. Mixing them up would also likely cause ECU and immobiliser issues, which you should discuss directly with the breaker for your specific vehicle.

Both years sit within the second-generation Fiat 500 (2007 onwards), and the 1.3 Multijet diesel engine code is your starting point for checking compatibility. That said, a 2014 unit is close to the 2015 facelift boundary, and mid-run production changes to mountings or ancillaries are possible, so you should confirm directly with the breaker that the donor engine code matches yours. ECU pairing and immobiliser coding requirements are also something to raise with the breaker before committing to a purchase.

Yes, gearbox type matters — an engine sourced from an automatic-gearbox car will have a different torque converter flange and potentially different engine management mapping compared with a manual equivalent. Always tell the breaker whether your car has a manual or automated-manual (Dualogic) gearbox so they can match accordingly. Combining the gearbox type with your exact engine code gives the breaker everything they need to find the right unit.

The Abarth 500 uses a tuned version of the 1.4-litre T-Jet petrol engine, which carries a different engine code from the standard 1.4 fitted to mainstream 500 models. A physical swap may be possible in principle, but ancillary differences, ECU calibration, and immobiliser pairing mean this is a complex job that goes well beyond a like-for-like replacement — confirm the full scope with the breaker and a trusted mechanic before proceeding. Never treat it as a routine used-engine swap.
