Jaguar/Land Rover 3.0 V6 diesel (306DTX) Remanufactured Bosch CRI3-20 Common Rail Injector
Hard starting or extended cranking; rough or uneven idle; loss of power under load; excess smoke from the exhaust; cylinder misfire or contribution fault codes. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector back-leak beyond specification; nozzle wear degrading the spray pattern; combustion gas leaks past the injector seat washer. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Run a comparative leak-off (back-leak) test across all injectors before condemning a single unit. Compare requested vs actual rail pressure in live data at idle and under load. Inspect injector connectors and wiring before replacing hardware. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 0445117052 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12 months and its calibration data on file.
The 0445117052 trusted family covers 8 verified vehicle fitments across 2 makes: Jaguar and Land Rover. Every fitment listed is registry-verified.
0445117052 cross-references 6 further OE numbers, including 0445117053, 0445116060, JDE39003, LR063300, LR078606 and FW939K546AB. Always match the reference etched on your failed unit's body.
