Cheap Peugeot 106 Fuel Injector

It depends on the variant — not all 106 engines are fuel-injected. The early and smaller-capacity petrol engines (such as the 1.0 and some 1.1 units) used carburettors rather than fuel injection, while the larger petrol engines like the 1.4 and 1.6 (including the GTi) and all diesel variants used fuel injection. If you have a carburettor engine, you will not find fuel injectors on it — you would be looking for carburettor components instead, so it is worth checking your V5 or doing a VIN check to confirm your exact engine code before searching.

The Peugeot 106 ran in two main phases — Phase 1 from 1991 to 1996 and Phase 2 from 1996 to 2004 — and while some engines carried across both phases, the injectors fitted can differ between them. The engine code is the key detail here: if your Phase 1 and Phase 2 car share the same engine code (for example, the TU series engines used across both generations), there is a reasonable chance of compatibility, but ancillary and mounting changes mid-production mean you should confirm the specific part against your registration with the breaker before buying.

For fuel injectors, the trim level itself does not affect fitment — what matters is the engine code, not whether the car is badged XN, XR, XT, Rallye, or GTi. However, do bear in mind that different trims came with different engines, so a GTi with a TU5J4 1.6 engine will need a completely different injector to an XR fitted with a smaller TU engine. Always supply the engine code (found on your V5 or via a VIN check) to the breaker rather than relying on the trim name alone.

Yes, the 106 diesel — fitted with a 1.5 diesel engine in the Phase 1 and a 1.4 HDi unit in the later Phase 2 — does use fuel injectors, but diesel injectors are an entirely different type to petrol injectors and are not interchangeable between the two fuel types under any circumstances. When searching for a used injector, make sure both the engine code and the fuel type on your V5 match the donor vehicle exactly, and confirm this with the breaker against your registration.

The 106 GTi used the TU5J4 1.6 16-valve engine, which was also fitted to the Citroën Saxo VTS, so there is potential for cross-compatibility given the shared PSA engine family. However, whether injectors from a different production year or a Saxo VTS will directly interchange depends on whether the specific part numbers and any ECU or fuel system calibration match — ECU pairing and any coding implications are something you must confirm with the breaker against your registration rather than assume.

Used fuel injectors are a commonly sourced part for the 106 and can be a cost-effective solution, particularly for the older TU-series petrol engines which used simpler single-point or multi-point injection without the complex coding requirements of modern direct-injection systems. That said, whether your specific injector requires any ECU pairing or adaptation after fitting is something you should confirm with the breaker and your fitting garage against your exact registration, as this can vary by engine and system type.
