Land Rover Part Number: ERR3339 - Fuel Injector - 300Tdi
ERR3339 is a fuel injector for 300Tdi engines. Fitted to the fuel injection system, the assembly meters and sprays pressurised diesel into the combustion chamber; the injector holder locates the unit in the cylinder head while the nozzle atomises the fuel for efficient combustion. Replacement injectors are required when the nozzle is worn, the tip leaks or the internal metering valve no longer delivers fuel consistently. When fitting, the injector must be correctly seated and sealed in the cylinder head and connected to the high-pressure fuel lines and return as applicable for the 300Tdi system.
Please note: Compatible with EGR 300Tdi engines; not compatible with EDC-specified 300Tdi applications. Use the compatibility data below to confirm fitment against your V.I.N.

Frequently Asked Questions
The ERR3339 injector delivers metered, pressurised diesel into each cylinder of the 300Tdi engine using an integrated holder and nozzle to locate and atomise the fuel. Common failures include a leaking tip, worn nozzle or a sticking metering valve, which cause rough idle, poor throttle response and increased exhaust smoke. Replacement is required when these faults occur to restore correct fuel delivery and combustion.
