Description
Set of BOSCH injectors for 1.6 eHDI 68 kW engines. Mileage: 78,000 km.
Product Overview
High-quality Bosch injector set compatible with PSA 1.6 eHDI (68 kW) engines. Ideal for mechanics and experienced DIY enthusiasts looking to restore fuel delivery performance, reduce rough idling and eliminate misfires. Commonly searched under part numbers 0445110340, 1980S5 and 1980S6.
Function And Benefits
Injectors meter precise amounts of diesel into the combustion chamber at high pressure as part of the common-rail fuel system. A balanced and responsive injector set ensures correct atomization, consistent combustion, improved fuel economy and lower emissions. Replacing worn or leaking injectors restores engine smoothness, reduces white/black smoke and improves cold starts.

Installation Recommendation
Replacement should be performed by a qualified mechanic or an experienced DIYer with access to basic workshop tools. General steps: depressurize the fuel system, remove the engine cover, disconnect the injector wiring harnesses and high-pressure fuel lines, remove injector clamps and extract injectors from the head. Fit new sealing washers and reassemble in reverse order. Use the manufacturer’s torque settings for clamps and fuel-line fittings and bleed the fuel system before starting. Always work in a well-ventilated area and follow safety procedures when handling diesel. It is recommended to check return lines and fuel filter condition when replacing injectors.
Why The Part Most Commonly Fails
Diesel injectors commonly fail due to contamination (dirty fuel, clogged filters), varnish and carbon build-up on the nozzle, internal leakage from worn seals, or electrical faults in the injector solenoid. Fuel system overpressure or injector driver issues in the ECU can also lead to premature failure. Regular maintenance of the fuel filter and using clean fuel significantly extend injector life.
Signs Of Failure And Replacement Interval
Typical symptoms include rough idle, loss of power, increased fuel consumption, excessive smoke and engine warning lights. There is no fixed interval for injector replacement; life depends on fuel quality and maintenance. Inspect injectors if symptoms appear or during major service intervals — many units remain reliable beyond 150,000 km with proper care, while others may fail earlier if contaminated.
Notes For Installation
- Use new copper/sealing washers when fitting injectors to ensure leak-free installation.
- Check high-pressure fuel lines and banjo fittings for damage or corrosion.
- After reassembly, prime the fuel system and verify no leaks before starting the engine.
- Follow safe workshop practices: relieve fuel pressure and disconnect the battery if required by the vehicle manufacturer before starting work.
