Second Hand Fiat 500X Coil Pack

The Fiat 500X was sold in the UK with both petrol and diesel engines, and coil packs are only fitted to the petrol variants — diesel engines use a different ignition system and have no coil pack at all. The petrol engines include units such as the 1.4 T-Jet and 1.3 FireFly, so if your 500X is a petrol you will need a coil pack; if it is a diesel, this is not the part you need. Check your V5 or run a VIN check to confirm your fuel type before ordering.

The Fiat 500X was facelifted in 2018, and that update brought engine changes that are relevant to coil pack fitment — the pre-facelift 2014–2018 cars used engines such as the 1.4 T-Jet, while the post-facelift 2018-onwards cars moved to the 1.0 and 1.3 FireFly family. Because the coil pack follows the engine code rather than the model year, a 2016 and a 2020 car are very likely to use different coil packs, and you should supply your exact engine code to the breaker rather than relying on year alone. The engine code appears on your V5 or can be obtained from a VIN check.

Trim level makes no difference to coil pack fitment on the Fiat 500X — whether your car is a Pop Star, Cross, Sport, or any other UK trim, what determines the correct coil pack is the engine code, not the badge on the tailgate. A breaker will confirm compatibility using your registration or engine code, and any cosmetic differences between trims are completely irrelevant for this mechanical part. Give the breaker your engine code and you can be confident the trim name alone will not lead you wrong.

The number of coil packs matches the number of cylinders — a four-cylinder petrol 500X such as the 1.4 T-Jet has four coil packs, while a three-cylinder engine such as the 1.0 FireFly has three. It is common to replace just the faulty coil, but many mechanics recommend replacing them as a set because the others will have similar mileage and wear. When buying used from a breaker, make sure you confirm the engine code so you get the correct type and quantity for your specific engine.

The 1.4 T-Jet engine family was used across several Fiat models, and in many cases the coil packs share the same part number, making cross-model fitment possible in principle. However, ancillary and mounting details can vary between applications, so you should confirm compatibility against your specific engine code and registration with the breaker rather than assuming a straight swap. Providing your engine code — found on the V5 or via a VIN check — gives the breaker the best chance of supplying the right unit.

The single most useful piece of information is your engine code, which you can find on your V5 logbook or by running a VIN check — this tells the breaker exactly which ignition setup your petrol engine uses. You should also confirm your model year and whether your car is pre-facelift (2014–2018) or post-facelift (2018 onwards), as these generations commonly used different petrol engines. Trim level and body colour are irrelevant for this part, so there is no need to mention them.
