Product Details
0445110520 Common Rail Injector by the Numbers
Verified identity and fitment data for this complete CRI2-16 injector, supplied for the 2.3 common rail applications.
A complete injector is a different purchase from a repair part. The unit arrives built, with the solenoid, the control valve and the nozzle assembly already set to the reference design, so the job is a swap plus a coding step rather than a bench rebuild. Because each cylinder carries its own correction value, one 0445110520 diesel injector is normally bought per cylinder being replaced, and a workshop replacing a full set will order four. Reading the correction values before and after the swap is the quickest way to see whether the new unit has taken the trim the ECU expects.

Part number match
Match the number on your old unit to 0445110520, or to the reference Bosch 0445110418. Where the body carries the earlier number, the 0445110418 injector is the same article group as this one, and the pair should be treated as one application rather than two.
Where the number is hard to read, a photograph of the injector body and the engine code plate is usually enough for us to confirm the build.
As a Fiat Ducato injector it covers the 2006-2016 van, chassis cab and minibus bodies. The same reference serves as an Iveco Daily injector on the IV and V ranges, as a Citroen Jumper injector on the 2.3 HDi, and as a Peugeot Boxer injector on the equivalent model — a range of 2.3 diesel injector applications that share one article, offered here as a Multijet diesel injector replacement for the F1AE3481D.
Fitment verification
- Injector part number — match the etched code on the injector body to 0445110520 or the earlier 0445110418.
- Engine code plate — the plate on the block must read an F1AE3481D, F1AE3481C or F1AGL411 unit on Bosch common rail injection, not another family.
- Photo of the old injector — a picture of the body and the calibration code, so we match the revision and not just the engine.
What a complete injector does
On a common rail engine the injector is the only part of the fuel system that reaches into the combustion chamber, and the only one that can be coded per cylinder.
On a common rail diesel a shared rail holds fuel at pressure and each injector is triggered electronically to release its charge. That makes the injector the point where the electronic side of the engine meets the hydraulic side: a solenoid injector receives a signal from the ECU, the magnetic circuit moves the control valve, and the resulting pressure drop lifts the nozzle needle. Because all four units draw from the same rail, a single unit that no longer meters cleanly changes the burn across the whole engine rather than in one cylinder alone.
The distinction that matters when buying is between a complete injector and the parts inside it. A diesel fuel injector arrives as a sealed assembly, built and set; a nozzle, a control valve or a seal kit is a repair item for a bench rebuild. Both routes exist on this platform and the choice is usually about bench time and warranty exposure rather than about the part itself. A Bosch common rail injector and a compatible unit are described by the same terms in a parts catalogue, so the two fields that settle the match are the number on the body and the code the ECU expects.
Metering
Delivers the exact quantity the ECU asks for, across the full rail pressure range.
Timing
Sets the start and duration of injection, which is where idle quality and emissions are decided.
Coding
Carries a calibration value the ECU reads per cylinder, so the unit must be written in after fitting.
Because the unit is coded, the same physical part behaves differently depending on the cylinder it is written into. The calibration code compensates for the small manufacturing spread between units, and an ECU that has not been told which injector it is driving will run with default trims. That is why a swap is a two-part job: fit the unit, then write the code. The engine will usually start either way, which is exactly what makes the second step easy to forget.
A solenoid injector on this platform is a robust design, and most failures come from fuel contamination or from wear inside the nozzle assembly rather than from the solenoid itself. A unit that has begun to drift shows as a correction value that creeps away from zero over weeks, with soot, a lazy idle and a smell of unburnt fuel following behind it. Judging a unit on whether the engine still runs tells you almost nothing; judging it on the balance the ECU reports tells you nearly everything.
Two numbers worth separating: the injector number identifies the assembly you are holding, and the calibration code identifies how that individual unit should be trimmed. A unit that carries the right number but the wrong code will still allow the engine to run, and the balance values will look almost plausible — which is why we ask for both, and not the model name.
Diesel injector, diesel fuel injector, solenoid injector — three trade names
Which of those names a supplier writes on the offer depends on who is buying. A workshop ordering a replacement quotes the number on the old unit. A fleet parts desk sourcing for a van quotes the engine code instead. A distributor stocking the Bosch range quotes the series. The article behind all three labels is the same assembly, and so is the test that settles the match: the number on the body and the code the ECU expects.
That is the reason we ask for the injector number rather than the model name. Whether your own paperwork calls this a diesel injector, a diesel fuel injector or simply a solenoid injector for the CRI2-16 range, the code on the part is what we confirm, and the code we ship against is the one you state.

The line between a Bosch injector and a compatible one is a line about branding, not about function. What the specification above describes is a CR injector built to the CRI2-16 architecture: a solenoid actuator, a control valve and a nozzle assembly that together set the pressure at which fuel is released and the shape of the spray that follows. Because the assembly is tested as a whole, the numbers that matter most — timing, delivery and pressure — are the ones the bench produces rather than the ones a catalogue quotes, which is why they are left unpublished here rather than filled in from a similar listing. A high pressure diesel injector run on contaminated fuel will damage its own nozzle long before the actuator fails, so fuel quality is the single largest factor in how long a replacement lasts. Buyers comparing common rail injector specifications across suppliers should expect the same set of published fields from each, and the same honesty about the fields nobody publishes.
CR injector, solenoid injector, high pressure diesel injector — what the terms cover
All three terms describe the same assembly on this platform, and none of them narrows the specification. A counter serving workshops tends to write the part up with the shorter wording and quote the number on the old unit. A parts desk buying for a diesel fleet writes it up with another and quotes the engine. What arrives in the box is identical either way: a complete injector built to the CRI2-16 reference design.
What does change the specification is the revision, and the revision is not written in the trade name. Since a unit carries a calibration value the ECU reads per cylinder, an incorrect or unwritten code will leave the new unit running on default trims whatever the label on the carton says. That is a different failure mode from the older practice of grading a part by its description alone, and it is why we record both the article number and the coding step on the offer we send.
Diesel injector technology on this platform has been stable for well over a decade, which is what makes a complete replacement practical: the connector, the body and the clamping arrangement are shared across the year range, so the same assembly fits vans, chassis cabs and light trucks built in different years. Where a buyer writes the order as a CR injector and the supplier lists it as an injector solenoid valve assembly, both are naming parts of the same build, and the unit that arrives is the whole article rather than a component.
Failure Symptoms
Common rail injector failure signs to watch for on the CRI2-16 2.3 engines before a unit is replaced.
- Rough idle or a persistent misfire on one cylinder
- Excess fuel knock, especially when cold
- Noticeable power loss under load
- Higher fuel consumption than the vehicle’s norm
- Black or grey smoke from the exhaust
- Hard starting or extended cranking
- Correction values the ECU flags as out of range
- Uneven running that clears at higher engine speed
Injector failure symptoms overlap with rail pressure, wiring and compression problems, so a scan tool reading plus a return-flow test is the normal way to isolate a single unit. Summaries of the stored codes are grouped on our diesel fault codes page, and the list above can be read alongside live correction values rather than trusting the parts cannon.
Most diesel injector problems on this platform start with wear or fuel contamination rather than with the solenoid. The classic giveaway is a spray pattern that has gone coarse or asymmetric: the engine still starts, but it smokes and the cylinder balance drifts. Letting the engine run on until bad injector symptoms turn into a hard fault rarely saves money, because a unit that has been over-fuelling for weeks will usually have taken its glow plug and its piston crown with it. A replacement should follow a confirmed diagnosis: read the per-cylinder correction values, compare return flow across the four, and only then commit to the cylinder the ECU is constantly trimming. Renewing the set rather than one unit is worth considering on a high-mileage engine, where the remaining three are usually at the same stage of wear.
Replacement and coding notes
Fitting a complete injector is a cleanliness-critical job with a second, electronic step that decides whether the engine runs properly.
Confirm the code
Record the injector number and the calibration code of the unit you are removing before stripping anything.
Depressurise
Work on a clean bench and depressurise the fuel system before opening the circuit.
Clean the seat
Clean the injector bore and seat so nothing is trapped under the new unit, then fit a fresh sealing washer.
Fit and torque
Fit the assembly squarely and torque the clamp to the figure your workshop data gives for this engine.
Write the code
Enter the calibration value of the new unit with a suitable scan tool before the engine is run in earnest.
Check for leaks
Run to temperature and check the leak-off and the seat for weeping before a road test.
An injector replacement on this engine is normally done in the vehicle rather than on the bench, because the unit is a complete assembly and nothing inside it is being opened. The cleanliness discipline still applies: the bore must be spotless and the sealing washer new, or the unit will leak at the seat. A slide-hammer injector puller is the usual tool for a unit that has seized in its bore, and the bore itself must be checked for scoring before the new unit goes in. Where the job is being done as part of a head repair, an injector seal kit and a fresh set of clamps are worth ordering at the same time.
The injector coding step is the one most often missed. Until the new value is written in, the ECU will trim the cylinder on default assumptions, so the engine may idle poorly and smoke even though the mechanical work was done correctly. Help reading the values before and after is available through our fuel system maintenance notes.
Reference and interchange numbers
Need an injector cross reference or a 0445110520 equivalent? The interchange numbers below are the ones buyers match against. All are reference interchanges only.
Cross-checking against 0445110418 is safe only when the old unit carries that number, and 0986435212 and 0986435248 are listed alongside it as exchange references for the same build. A bosch injector cross reference is filed under both the current and the earlier number, so a search for a bosch 0445110520 listing and a search for the 0445110418 application lead to the same article. These numbers identify one article group; they are not a statement that this unit is an original-equipment part.
The complete unit carries its own number and its own calibration code, and the table above deliberately stops at article level. If your old injector is stamped with a number that does not appear here, send us a photograph of the body before ordering and we will check it against the CRI2-16 range.
Two suppliers can quote the same article under different wording — one listing a replacement injector, another an exchange unit for the 2.3 range, a third a short four-digit reference. None of those descriptions identifies the article on its own. The two fields that do are the full number and the engine the unit is built for, which is why we record both on the offer we send.
Build quality and inspection
Every unit is built from precision components and checked before it leaves us.
Each unit is built from precision components to the CRI2-16 architecture used by the F1AE3481D engine family, so the delivery and the spray pattern match the injector it was built for. The solenoid and the control valve are matched to the body, and the nozzle assembly is set as part of the build rather than added afterwards.
The internal numbers inside the assembly are rev-dependent: confirm by injector revision or by the number on the body before ordering, because one 2.3 platform can carry more than one revision across its production years.
Units are checked mechanically and hydraulically before they leave us. Where a workshop wants figures rather than a pass or fail, the unit can be run on a common rail injector tester and the injector test report supplied with the order.
Alongside complete injectors we hold common rail injector parts for this family, so a rebuilder can service an assembly instead of replacing it whole. Where a workshop is ordering an injector rebuild kit rather than a complete unit, the internal numbers are confirmed against the injector revision you send us.
Wholesale & bulk supply
Vidishi Auto is an export supplier of diesel fuel system parts, serving workshops, rebuilders and distributors who service Bosch CRI2-16 injectors in volume.
4 pcs, with tiered terms as quantity rises.
Matched batches for engine sets and workshop stock.
Each unit is capped and carton-sealed for freight.
Our diesel injector wholesale programme runs from a small batch through to container quantities, and as one of the common rail injector supplier networks serving export workshops we consolidate mixed fuel system orders into a single shipment. Where a workshop buys four units at a time to cover a full engine set, the order is quoted on tiered terms rather than on a single unit. Buyers who place a standing order with a bosch injector supplier in the export market usually want the same article from batch to batch, which is what our stock holding is arranged to give. Send your required quantity and destination port for a quotation. Tiered terms and lead times are on our wholesale pricing page.
Packaging, weight and shipping
Export packing and freight for single boxes through container volumes, quoted per order.
26 × 6.5 × 6.5 cm.
1.600 kg gross per pack.
4 pcs.
Capped unit, wrap, carton sealed.
The 26 × 6.5 × 6.5 cm pack is sized for a single capped unit, so a set for a four cylinder engine ships as a compact carton rather than a stack of oversize boxes. The packaged shipping weight is 1.600 kg gross per pack, which covers the unit, its protective cap and the sealed bag. Freight options and delivery estimates are set out on our shipping information page; returns and cancellations are covered under returns.
The diesel injector price for this reference moves with quantity and freight, so the figure that applies to your order is the one quoted and confirmed before dispatch. Whether you are comparing a quotation from a local distributor or an injector price from another exporter, ask for it to include freight and the warranty terms so the comparison is like for like.
For a single unit the courier option is usually the fastest route; for a workshop quantity, a consolidated carton or a pallet brings the freight cost per piece down. Where a shipment is going to a resale address, ask for the commercial invoice and packing list to be issued with the dispatch documents so customs clearance is not held up at the destination.
