A buyer's guide to used Fiat 500 fuel injector

No two fuel injectors are quite the same across different vehicles, so getting the specifics right matters when you buy used, second hand or a replacement. Answer a few quick questions below and breakers will only quote if they have the exact matching part in stock:

Fitment questions

Do all Fiat 500s have fuel injectors?

No — only petrol-engined Fiat 500s use fuel injectors in the conventional sense; the 1.3 Multijet diesel variant uses a common-rail injection system with its own diesel injectors, which are entirely different parts. If you have a petrol 500 (for example the 1.2, 1.4, or turbocharged 0.9 TwinAir or 1.4 T-Jet), it will have petrol fuel injectors. Make sure you know your fuel type before searching, as petrol and diesel injectors are not interchangeable.

Will a fuel injector from a 2010 Fiat 500 fit my 2017 Fiat 500?

The modern Fiat 500 (third generation, launched in 2007 and running through to around 2024 in the UK for this body style) covers a long production span, and injector compatibility hinges on the engine code rather than the model year alone. A 2010 and a 2017 car carrying the same engine code — for example both running the 169A4 (1.2 petrol) — may well share the same injector, but there were running production changes across this period that could affect ancillary fitment details. Confirm compatibility with the breaker using your exact engine code, which you'll find on your V5C or via a VIN check.

Does the Fiat 500 TwinAir use the same fuel injectors as the 1.2 petrol?

No — the 0.9 TwinAir (engine code 312A2 or similar) is a turbocharged two-cylinder unit with its own specific injector specification, and it is not interchangeable with those from the naturally aspirated 1.2 (engine code 169A4). Always match the injector to the engine code, not just the body or the badge. Give the breaker your engine code and fuel type to make sure you get the right part.

Does the trim level — Pop, Lounge, Sport — affect which fuel injector I need?

No — trim level has no bearing on fuel injector fitment; a Pop and a Lounge with the same engine code and fuel type will use identical injectors. What matters is the engine code, fuel type (petrol or diesel), and the engine variant (naturally aspirated versus turbocharged). Focus entirely on matching the engine code when searching, and ignore trim badging.

Do I need to get the ECU or immobiliser recoded after fitting a used fuel injector to my Fiat 500?

This is something you should confirm directly with the breaker or a Fiat-specialist garage before buying, as injector coding requirements can vary depending on the engine management system fitted to your specific car. Some modern direct-injection systems do require injector coding to the ECU for optimal fuelling accuracy, while simpler port-injection systems often do not. We cannot state this as fact for your individual vehicle, so please check with a qualified mechanic or the breaker before proceeding.

Can I use a fuel injector from a Fiat 500C (convertible) on my standard Fiat 500 hatchback?

Yes, in principle — the 500C shares its engines and drivetrain with the standard 500 hatchback, so a matching engine code means the injector itself should be the same part. Body style makes no difference to injector fitment; what matters is that the engine code, fuel type, and engine variant match between the donor car and yours. Confirm the engine codes align when speaking to the breaker, and you should be fine.
