Bosch Common Rail diesel injectors rely on precise fuel metering to keep combustion stable. Reference 445110141 (cross-ref 0 445 110 141) must be matched to the old unit markings before installation.
Part identification and catalog/cross-references
Diesel injector reference 445110141 is a Bosch Common Rail injector intended for 2.5 dCi applications across Nissan, Opel, and Renault families listed for this part. The same unit is also cataloged as 0 445 110 141, which should be used as a cross-reference during matching.
When selecting a replacement injector, match the reference-number on the old unit to 445110141 and confirm the cross-reference 0 445 110 141 corresponds to the same injector design. The correct injector body/connector shape and the internal calibration must align with the engine’s Common Rail control strategy, otherwise fuel metering and spray characteristics can deviate.
Because this replacement is described as a general overhauled diesel injector for reference 0445110141, the key selection step is still the same: compare the reference-number and the vehicle/engine data against the compatibility listing before ordering. Do not rely on brand alone—injectors for different 2.5 dCi variants can share similar physical appearances while still differing in calibration.

Fitment checks and installation cautions
Before fitting the Bosch injector with reference 445110141, verify the reference-number on the old injector and cross-check it with 0 445 110 141. The supplied compatibility notes explicitly require matching reference-number, OEM-Nummern (if present), engine code letters, and vehicle data against the old unit.
Common Rail injector fitment is sensitive to calibration and sealing. Even if the vehicle model matches the Nissan Interstar dCi 100/115/120 list, a mismatch in injector calibration can affect fuel metering accuracy and spray pattern, which directly impacts combustion quality, cold-start behavior, and engine running smoothness.
During replacement, compare the injector’s connector/body shape and any markings on the old unit to ensure the correct injector design for reference 445110141. If the old unit does not clearly match the listed reference-number, stop and re-check the part number and engine code rather than forcing a fit.
Because the replacement is described as a general overhauled Bosch injector for reference 0445110141, treat it as a calibrated component: avoid contamination and keep the injector seating surfaces clean. Any debris around the injector sealing area can disturb sealing and contribute to poor running, even when the injector reference 445110141 and cross-reference 0 445 110 141 are correct.
Symptoms and selection notes for 2.5 dCi Common Rail
A worn or mismatched diesel injector in a Common Rail system can cause unstable combustion and rough engine running, and the supplied description links injector condition to combustion, engine running, and power delivery returning to a clean technical level. With reference 445110141, the goal is restoring precise fuel metering so the engine can achieve correct combustion and smoother operation.
Common selection triggers for reference 445110141 include complaints tied to injector-related running issues: poor cold-start behavior, uneven idle, and degraded performance response on 2.5 dCi applications where the injector is responsible for high-precision fuel injection into the combustion chamber. If the symptoms started after injector work or after a previous part swap, confirm the installed unit’s reference-number against 445110141 and 0 445 110 141.
Do not select solely by vehicle model year for Nissan Interstar (X70) dCi 100/115/120. The compatibility list shows multiple production ranges, and the supplied notes stress that the correct vehicle assignment is determined using compatibility data and vehicle widgets—so the safest approach is to verify reference-number and engine code letters before ordering the Bosch injector.
When diagnosing, remember that even small deviations in injection pressure, injected quantity, or spray pattern can lead to drivability issues. That is exactly why matching 445110141 (and cross-reference 0 445 110 141) to the old unit matters: the injector must be the correct calibration for the engine’s Common Rail control strategy.

Frequently Asked Questions
How do I verify a Bosch diesel injector reference number 445110141 before replacement?
Check the reference-number printed or stamped on the old injector and compare it to 445110141. Then cross-check the catalog cross-reference 0 445 110 141 and verify the engine code letters and vehicle data match the compatibility listing.
Will a Nissan Interstar dCi 100 injector 445110141 fit a different dCi variant?
The compatibility list covers specific Interstar dCi 100/115/120 production ranges, but injector calibration can differ between variants. Use the old unit markings and confirm the reference-number 445110141 (and 0 445 110 141) before fitting.
What symptoms point to a faulty Common Rail injector on a 2.5 dCi engine?
The injector affects combustion quality, engine running, and power delivery, so issues like rough running and poor cold-start behavior can be linked to injector problems. If the injection quantity or spray pattern is off, drivability and performance response can degrade.
What does the cross-reference 0 445 110 141 mean for injector selection?
It is a catalog number that should correspond to the same injector reference family as 445110141. Use it during matching to confirm you are ordering the correct injector design for the engine and old unit.
Why is matching OEM-Nummern and engine code letters necessary for injector 445110141?
Even when the vehicle model looks correct, injector calibration and design details must match the engine’s Common Rail control strategy. The supplied fitment notes require confirming reference-number, OEM-Nummern (if applicable), engine code letters, and vehicle data against the old unit.
