Peugeot 307 Fuel Injector Replacement Parts

The 307 ran from 2001 to 2008, with a facelift arriving in 2005, so your question spans that boundary. Injector compatibility depends primarily on the engine code rather than the model year or facelift, so a same-engine-code injector from a pre-facelift car can often cross over — but ancillary and mounting details can change across production runs. Give your engine code (shown on your V5 or via a VIN check) to the breaker and ask them to confirm against your registration before buying.

Yes, the engine code is the single most important detail for injector fitment on the 307. The HDi range covered several different diesel units over the car's life, including 1.4, 1.6, and 2.0 HDi variants, each with their own injector specification. Find your engine code on the V5 or via a VIN check and supply it to the breaker so they can match the exact unit rather than going by engine size alone.

All Peugeot 307 petrol engines are fuel injected, so yes, your car does have injectors. The 307 was launched in 2001 and never used a carburettor, so a used injector is a legitimate repair option. Make sure to supply your engine code to the breaker, as the petrol range included different units such as the 1.4, 1.6, and 2.0 with varying injector specifications.

Trim level has no bearing on injector fitment — the injector follows the engine, not the badge or equipment level. An S and an SE with the same engine code will use the same injector, so you do not need to match trim. What matters is the engine code, fuel type, and build date, which your breaker will use to confirm the right part against your registration.

Whether a used injector requires coding or programming to your vehicle's ECU is something you should confirm with your fitting garage before purchasing, as this can vary by engine variant and affects labour cost. On some 307 diesel units the injector trim codes need to be entered into the ECU after fitting, which requires diagnostic equipment. Confirm this with the breaker and your mechanic against your specific registration so you know exactly what you are taking on.

Engine-code matching is a good starting point when looking across different Peugeot models that share powertrains, and the 307 did share some engines with other PSA-group vehicles. However, ancillary fittings, rail connections, and harness plugs can differ between models even with a shared engine code. Route this question to the breaker with both registration numbers so they can check the specific part numbers before committing to a purchase.
