Peugeot 406 Fuel Injector Replacement Parts

Fuel injectors exist on both petrol and diesel 406 variants, but the type differs significantly: petrol engines use port fuel injectors, while diesel engines (such as the HDi turbodiesels) use high-pressure direct injectors matched to the fuel system. A petrol injector will never interchange with a diesel injector, so getting the fuel type right is the first thing to confirm before searching. Always supply your engine code from the V5 or a VIN check to ensure you and the breaker are looking at the same unit.

The 406 was produced from 1995 to 2004, with a facelift arriving in 1999 that brought revised front styling and some mechanical updates. Whether injectors cross that 1999 boundary depends entirely on the engine code — if the code is the same before and after the facelift, fitment is likely, but ancillary and mounting changes can occur mid-production, so you should confirm the specific part against your registration with the breaker. Give the breaker your engine code rather than just the year to avoid mismatches.

Trim level has no effect on which fuel injector you need; fitment is governed entirely by the engine code and fuel type, not by whether the car is badged LX, GLX, SR, or Executive. Two 406s with the same engine code will take the same injector regardless of trim. Focus your search on matching the engine code exactly and leave the trim badge out of the conversation with the breaker.

No — the 1.9 TD is an older indirect-injection diesel engine, while the 2.0 HDi is a later common-rail direct-injection unit; the two systems are completely different and their injectors are not interchangeable. The HDi injector operates at much higher pressure and is a fundamentally different design. Always match on engine code, not just the stated capacity, as these codes confirm exactly which injection system your car uses.

If the engine code is identical on both cars, there is a good chance the injectors will interchange, as the 2.0 HDi unit carried through much of the post-facelift 406 production from 1999 to 2004. However, running changes can occur within a production run that affect fitment even when the headline code looks the same, so you should confirm this against your specific registration with the breaker before purchasing. Also be aware that HDi injectors may need coding or calibration to the fuel system — confirm with the breaker whether the unit you are buying has been tested and whether any adjustment will be needed.

Body style makes no difference to fuel injector fitment; the engine and its injection system are the same regardless of whether the 406 is a saloon or estate. What matters is the engine code, fuel type, and year within the production run. Strip the body style from your search criteria and focus purely on getting the engine code to the breaker.
