0445116064 — Technical Research
Bosch piezo common-rail injector for the Land Rover/Jaguar 3.0-litre V6 diesel (engine 306DT, higher-output 306DTX) fitted to the Range Rover, Range Rover Sport, Discovery 4 and Jaguar XF/XJ 3.0 D. Land Rover OE LR017923. Each injector carries a correction code that must be programmed to the ECU with Land Rover SDD/Pathfinder on fitment. The 3.0 V6 is sensitive to fuel filtration; failures are driven by contamination and back-leakage wear. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.

A leaking injector unbalances cylinder fuelling on the 3.0 V6.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation cuts power.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationProgram the injector correction code to the correct cylinder with Land Rover SDD/Pathfinder before road test.
- InstallationRenew the combustion seal and clamp hardware; torque to spec.
- MisdiagnosisRead live back-leakage data to find the weak cylinder before removal.
- WarningThis is the 3.0 V6 (306DT) piezo injector - it is not the 2.0 four-cylinder Ingenium (204DT) unit; confirm LR017923 stamped on the old injector.
- TestingBench-test on a piezo-capable CR tester across delivery and back-leakage points before refit.
What is Bosch injector 0445116064?+
A Bosch piezo common-rail diesel injector for the Land Rover/Jaguar 3.0 V6 diesel (306DT/306DTX). Land Rover OE LR017923.
Which vehicles use 0445116064?+
Range Rover, Range Rover Sport, Discovery 4 and Jaguar XF/XJ 3.0 D, roughly 2009-2018.
Is it solenoid or piezo?+
It is a Bosch piezo common-rail injector.
Does 0445116064 need coding?+
Yes - program the injector correction code to the correct cylinder with Land Rover SDD/Pathfinder when fitting.
What is the OE part number?+
Land Rover LR017923 references Bosch 0445116064.
Does it fit the 2.0 Ingenium (204DT)?+
No - the 2.0 four-cylinder Ingenium uses a different injector. The 3.0 V6 (306DT) uses the piezo 0445116064; confirm the OE number stamped on your injector.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 3.0 V6 run rough?+
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the weak cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured 0445116064 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then correction-coded on fitment.
What is the difference between 0445116064 and 0445117052?+
Both are Bosch injectors for the JLR 3.0 V6 (306DT/306DTX). 0445116064 (0445116-series) covers the earlier build (Range Rover/Jaguar/Discovery 4, ~2009–2016); 0445117052 (0445117-series) is the later supersession for the 306DTX (Discovery 5/Range Rover 2017+). Match the OE number and model year before ordering.
