Denso 16600-5X30A 2.5 dCi (YD25DDTi) Common Rail Injector

AI Technical Summary

Denso common-rail solenoid injector (Denso number 295050-1050, code DCRI301050) for the Nissan 2.5 dCi YD25DDTi engine, fitted to the Navara D40, NP300 Pickup and Cabstar. Nissan OE number 16600-5X30A. Common failure drivers on the YD25 are poor fuel filtration, fuel contamination and water ingress. Key symptoms: Hard starting / extended cranking; Rough idle and vibration; Black smoke; Loss of power / limp mode. Common failure modes: Internal wear / high back-leakage; Corrosion from water in fuel; Nozzle coking / poor atomisation.

Common Symptoms

Hard starting / extended crankinghigh

Injector back-leakage drops cranking rail pressure on the YD25, making the engine slow to start, especially cold.

Rough idle and vibrationhigh

A worn or leaking injector unbalances cylinder fuelling, producing a shaky idle on the 2.5 dCi.

Black smokemedium

Poor atomisation from a worn nozzle over-fuels the cylinder.

Loss of power / limp modemedium

Out-of-range injector delivery triggers reduced performance or limp mode on the YD25DDTi.

Knocking / diesel rattlemedium

A leaking injector causes a pronounced top-end knock on the YD25, often mistaken for timing-chain noise.

Increased fuel consumptionmedium

Over-fuelling or internal leakage wastes fuel and can fail emissions.

Workshop & Fitting Notes

InstallationThe YD25 is sensitive to fuel quality - replace the fuel filter and check for water/debris before fitting the new injector, or the replacement will fail again.
InstallationAlways fit a new copper sealing washer and use the correct tightening torque - missing seals or over-torque are common YD25 installation faults.
codingEach Denso common-rail injector carries an individual correction (ID/QR) code that must be written into the ECU after fitting; without coding the engine runs on default trim and may log cylinder-balance faults.
MisdiagnosisRead live injector correction/back-leakage values to find the weak cylinder before removal rather than replacing all injectors blind.
WarningWater-in-fuel causes corrosion on the YD25 - address the contamination source before fitting replacements.
TestingTest on a Denso-capable common-rail bench across delivery and back-leakage points before refitting.

Frequently Asked Questions

What is Denso injector 16600-5X30A?+

A Denso common-rail solenoid diesel injector for the Nissan 2.5 dCi YD25DDTi engine. Denso number 295050-1050 (code DCRI301050); Nissan OE number 16600-5X30A.

Which vehicles use 16600-5X30A?+

Nissan Navara (D40), NP300 Pickup and Cabstar with the 2.5 dCi YD25DDTi engine.

Is it solenoid or piezo?+

It is a Denso solenoid common-rail injector.

What is the Denso number for 16600-5X30A?+

Denso 295050-1050, also referenced as DCRI301050. The Nissan OE number is 16600-5X30A.

What are the symptoms of a failing 16600-5X30A?+

Hard starting, rough idle and vibration, black smoke, diesel knock, loss of power or limp mode, and higher fuel consumption.

Why does my YD25 Navara knock or rattle?+

A leaking injector causes a top-end knock on the YD25 that is often mistaken for timing-chain noise. Bench-test to confirm the faulty cylinder before replacing.

What causes these injectors to fail?+

Poor fuel filtration, fuel contamination and water in the fuel - so fix the cause, not just the injector.

Do I need to code the injector to the ECU?+

Yes. Each Denso injector has an individual correction code that must be written into the ECU after fitting, or the engine will run on default trim and may log cylinder-balance faults.

Should I replace one or all four?+

Diagnose each with live correction and back-leakage values; on high-mileage YD25 engines failures often cluster, so check all of them.

Why renew the copper washer?+

It is a one-use crush seal; a missing or reused washer causes blow-by and carbon build-up around the injector.

Does a remanufactured 16600-5X30A perform like new?+

A properly remanufactured injector is bench-tested and recalibrated to the Denso plan to meet original delivery and back-leakage specifications.

Does it fit the Pathfinder R51?+

The Pathfinder R51 uses the YD25DDTi engine, but injector revisions vary by model year and emissions - confirm the exact number stamped on your original injector by VIN before ordering.
