Description
Overview
High-quality Siemens common-rail fuel injector designed for 2.0 HDi diesel engines. OEM part number 9657144580 with cross-references 9647247280, 1980J5 and 1980Z0. Compatible with a range of Citroën and Peugeot 2.0 HDi applications and selected Fiat, Ford and Volvo vehicles. Supplied tested and guaranteed functional, making it a reliable replacement for workshops and competent DIY mechanics.
Function and Benefits
- Precise fuel metering and atomisation for optimal combustion and engine response.
- Designed for common-rail diesel systems used on 2.0 HDi engines.
- Restores smooth idle, reduces smoke and helps regain lost power compared to a worn or leaking injector.
- Direct OEM cross-reference fitment reduces risk of compatibility issues when replacing by part number.
Symptoms Of A Faulty Injector
- Rough idle or engine misfires
- Increased fuel consumption
- Black or grey exhaust smoke, especially under load
- Hard starting or extended cranking
- Fuel smell, visible leaks at the injector seals, or engine warning light related to fuel delivery
Replacement And Installation
Replacement should be carried out by a trained technician or a competent DIY mechanic familiar with diesel common-rail systems. Basic procedure:
- Relieve the fuel system pressure and disconnect the battery for safety.
- Remove engine covers and components necessary to access the fuel rail.
- Unplug the electrical connector from the injector and remove the fuel rail mounting bolts.
- Carefully extract the injector from the rail; some models require a puller or special tool to avoid damage.
- Replace injector O-rings/seals with new items, lubricate seals lightly with clean diesel or OEM lubricant and install the new injector.
- Tighten fittings to manufacturer torque specifications, reconnect electricals, prime the fuel system and check for leaks before starting the engine.
Note: Some modern ECU systems may require injector coding or adaptation with a diagnostic tool after installation. Always consult the vehicle workshop manual or diagnostic platform for model-specific procedures and torque values.
Durability And Common Failure Causes
Injector life depends on vehicle usage and fuel quality. Common causes of injector failure include contaminated fuel, clogged filters, varnish and deposits from poor fuel, electrical coil faults, and degraded seals causing leaks. Regular fuel filter changes and clean fuel help extend injector life. In many cases injectors remain serviceable beyond 150,000 km, but performance and longevity vary by service history.
