Used Peugeot 306 Fuel Injector

The Peugeot 306 ran from 1993 through to 2002, with a significant facelift in 1997 that updated bodywork and some mechanical details, so a 1994 and 1997 car sit either side of that boundary. Engine code is the key factor here — if both cars share the same engine code (for example both running the XU5JP4 or XUD unit), there is a reasonable chance the injectors will interchange, but whether any ancillary or mounting changes were made at the 1997 facelift is something you should confirm with the breaker against your registration. Always supply your engine code, which you can find on your V5C or via a VIN check, when requesting a quote.

No — petrol and diesel fuel injectors are entirely different components and are not interchangeable under any circumstances. Diesel 306s used indirect-injection diesels (such as the XUD family) or later direct common-rail units, while petrol variants used port-injected injectors suited to their respective engines. Always specify your fuel type and engine code when searching, as supplying the wrong type would result in a part that physically cannot fit.

Trim level does not affect injector fitment — what matters is the engine code, not the badge on the back of the car. Two 306s wearing different trim badges but sharing the same engine code (for instance two cars both running the XU10J4RS in the GTi-6 and Rallye) would use the same injectors. When contacting a breaker, give them your engine code rather than your trim name and they will be able to match the correct part to your car.

Yes, all diesel variants of the Peugeot 306 do have fuel injectors, fitted as part of the indirect or direct fuel delivery system depending on the engine. Earlier diesel engines such as the XUD family used indirect injection with mechanical injectors, while later variants moved to more modern units, so the injector type differs meaningfully between engine codes. Make sure you provide your exact engine code to any breaker so they can match the correct injector specification to your car.

Because Peugeot and Citroën shared engines across several models during the 306's production run, injectors from a vehicle running an identical engine code — such as the XUD or XU-series units — may well be compatible. However, whether the injector is a straight swap depends on the exact engine code and specification matching, and you should always confirm this with the breaker against both registrations before purchasing. Sourcing from a 306 donor car where possible reduces uncertainty, but a knowledgeable breaker can advise on cross-model compatibility.

On older carburettor-era or early injected 306s this is generally less of a concern, but whether a used injector requires any coding or pairing to your vehicle's ECU is something you must confirm with the breaker against your specific registration, as this can vary by engine and model year. It is not something that can be stated as a blanket rule across all 306 variants. A breaker familiar with these cars will be able to advise you before you commit to a purchase.
