0445111019 — Technical Research
Bosch CRI2-18 solenoid common-rail injector for the Jaguar Land Rover 2.0 Ingenium diesel (AJ200D / 204DT). JLR OE LR079542 (related LR073710/JDE40503/AJ813375). Replacements are coded to the ECU with the injector correction value. Failures are driven by poor fuel filtration, contamination and back-leakage. 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 2.0 Ingenium.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation triggers derate.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationCode the injector correction value to the correct cylinder with JLR 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.
- WarningFix contamination (filter/water/debris) first; the Ingenium is sensitive to fuel quality.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is Bosch injector 0445111019?+
A Bosch CRI2-18 solenoid common-rail diesel injector for the Jaguar Land Rover 2.0 Ingenium diesel (AJ200D / 204DT). JLR OE LR079542.
Which vehicles use 0445111019?+
Land Rover Discovery Sport, Range Rover Evoque, Discovery 5/Velar and Jaguar XE/XF/F-Pace/E-Pace 2.0 D (Ingenium).
Is it solenoid or piezo?+
It is a Bosch solenoid (CRI2-18) common-rail injector.
Does 0445111019 need coding?+
Yes - code the injector correction value to the correct cylinder with JLR SDD/Pathfinder when fitting.
What are the OE part numbers?+
JLR OE LR079542 and LR073710 reference Bosch 0445111019; JDE40503/AJ813375 are related numbers.
Does it fit both single and twin-turbo Ingenium?+
Confirm the engine variant and the OE/Bosch number stamped on the injector before fitting - several Ingenium revisions exist.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 2.0 Ingenium 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 0445111019 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then coded on fitment.
