Product Details
DLLA142P1595 Injector Nozzle by the Numbers
Verified identity and fitment data for this CRI2-16 nozzle, supplied for the 0445110273 injector family.
The DLLA142P1595 injector nozzle is a bench-fit component rather than a complete injector: it seats inside the 0445110273 body, where its needle lifts to release the charge the injector has pressurised. A single dlla142p1595 nozzle serves one injector, so a rebuild usually calls for one nozzle per unit being refreshed. Reading the correction value each cylinder reports is the quickest way to tell whether the nozzle at that cylinder has started to drift out of trim.

Part number match
Match the number on your old nozzle to DLLA142P1595, or to the reference Bosch 0433171974. If your injector carries 0445110273, 0445110435, 0445117077 or 0986435165, then the 0445110273 nozzle, the 0445110435 nozzle, the 0445117077 nozzle and 0986435165 are the same article group as this one.
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 nozzle it covers the 2006-2014 van, chassis cab and minibus bodies. The same reference serves as an Iveco Daily injector nozzle for the IV and V ranges, and as a UAZ Patriot injector nozzle on the 2.3 diesel sold from 2006.
Fitment verification
- Injector part number — match the etched code on the injector body to 0445110273, 0445110435, 0445117077 or 0986435165.
- Engine code plate — the plate on the block must read an F1AE0481 unit on Bosch common rail injection, not another family.
- Photo of the old nozzle — a picture of the nozzle and injector body so we match the code and not just the engine.
What the nozzle does in the injector
Inside a Bosch CRI2-16 injector the nozzle is the last element in the fuel path, and the only one the combustion chamber ever sees.
On a common rail diesel a shared rail holds fuel at pressure and each injector is triggered electronically to release its charge. Inside the injector the nozzle is the last element in the chain: pressurised fuel reaches the nozzle holder, and when the injector opens, the nozzle needle lifts off its lapped seat so the fuel is forced through the spray holes and atomised into the combustion chamber. A common rail nozzle that has worn no longer meters cleanly, and the effect is felt across the whole engine rather than at one cylinder alone.
Two names describe the same article. In Bosch service literature it is filed as a nozzle, and on a diesel engine as a diesel injector nozzle; in parts catalogues the same piece is listed as a common rail injector nozzle or a fuel injector nozzle. Either way it is the small, precision-lapped part at the tip of the injector, and it is the component a spray-pattern problem usually points to.
Atomisation
Turns pressurised fuel into the fine mist the combustion chamber can burn cleanly.
Spray pattern
Sets the number, angle and direction of the jets through the spray holes.
Sealing
The needle and body are lapped as a pair, so the nozzle holds rail pressure between injections.
The nozzle is a matched pair rather than a single part: the body carries the spray holes and the nozzle needle is lapped into it, so the two are renewed together. On this architecture the DLLA-type body is a slim pencil nozzle that sits in the injector’s nozzle holder and is clamped by the retaining nut, with the needle free to lift a few microns on every injection. Once the lapped fit between needle and body is lost, no cleaning routine brings it back.
Because the nozzle is the final metering element, a worn body changes the shape of the spray long before it stops the engine. Soot loading rises, the burn gets lazy and the correction values the ECU applies drift away from zero. That is why a nozzle is judged on spray pattern and on the balance the ECU reports, not on whether the engine still runs.
Two numbers worth separating: the nozzle number identifies the article you are holding, and the injector number identifies the assembly it seats in. A nozzle that carries the right number but is fitted to the wrong injector revision will still allow the engine to run, and the balance values will look almost plausible — which is why we ask for the injector number rather than the model name.
Fuel injector nozzle, diesel injector nozzle, common rail nozzle — three trade names
Which of those names a supplier writes on the offer depends on who is buying. A workshop ordering for a bench rebuild asks for the spray component and quotes the injector number. A fleet parts desk sourcing for a van or a light truck quotes the engine code instead. A distributor stocking the Bosch range quotes the trailing DLLA digits. The article behind all three labels is the same piece, and so is the test that settles the match: the number etched on the body, not the wording on the invoice.
That is the reason we ask for the injector number rather than the model name. Whether your own paperwork calls this a fuel injector nozzle, a diesel injector nozzle or simply a Bosch replacement nozzle, the code on the part is what we confirm, and the code we ship against is the one you state.
Stock is held by reference rather than by model year, which is why the same fuel nozzles serve the van, chassis cab and light truck applications set out above. A rebuild batch spanning more than one of those bodies still draws on a single article number.

This dlla142p1595 bosch nozzle is supplied as the nozzle and needle assembly only. The diesel nozzle seats in the injector’s nozzle holder against a lapped face, and a fuel nozzle run on contaminated fuel will score that face. The nozzle spray hole set and the nozzle spray angle are fixed by the reference design: the 142 degrees recorded in the part number, a figure shared by every article in the DLLA 142 P family. A spray hole that has eroded will not deliver the same pattern at rail pressure, which is why the nozzle and needle are replaced as a set rather than re-lapped in the field.
Fuel nozzle and diesel nozzle: what the two trade terms cover
Both terms are used for this same assembly, and neither narrows the specification. A counter serving workshops tends to write the part up with the shorter wording and quote the article number. A parts desk buying for a diesel fleet writes it up with the other and quotes the injector it is built for. What arrives in the box is identical either way: a body carrying the spray holes, and the needle lapped into it as a matched pair.
What does change the specification is the family code. The trailing DLLA 142 P digits fix the spray angle at 142 degrees, and that figure is shared across every article in the family — so two listings that read almost the same but differ in the last digits are two different nozzles. If your own paperwork says diesel nozzle and ours says fuel nozzle, compare the trailing digits rather than the wording before you commit the order.
A diesel fuel nozzle for this platform is judged on the spray it produces at rail pressure rather than on the label on the carton, and the same holds when it is sold as a Bosch nozzle for the CRI2-16 range. The clamping section in Bosch service data is the nozzle holder; in the aftermarket the same section is written up as the diesel nozzle holder, and it is part of the injector body rather than a separate item in the box.
Failure Symptoms
Common rail nozzle failure signs to watch for on CRI2-16 injectors before the nozzle 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
- Return flow readings the ECU flags as out of range
- Uneven running that clears at higher engine speed
These injector nozzle 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 common rail nozzle failure on this platform comes from wear and fuel contamination rather than from the injector solenoid. The classic giveaway is a nozzle spray pattern that has gone coarse or asymmetric: the engine still starts, but it smokes and the cylinder balance drifts. An injector nozzle cleaning routine can recover a lightly coked nozzle, yet once the lapped needle and body have worn there is nothing left to clean, and the nozzle has to be renewed. An injector nozzle replacement should follow a confirmed diagnosis: read the per-cylinder correction values, compare return flow across the four, and only then commit to the nozzle that the ECU is constantly trimming. Renewing all four nozzles as a set is worth considering on high-mileage injectors, where the remaining units are usually at a similar stage of wear.
Rebuild and installation notes
Fitting a nozzle is a cleanliness-critical job: the nozzle and needle are lapped as a matched pair and the injector body they sit in cannot be re-lapped in the field.
Confirm the code
Record the injector number and the calibration code before stripping the unit.
Depressurise
Work on a clean bench and depressurise the fuel system before opening an injector.
Strip and clean
Remove the retaining nut, lift out the old nozzle and needle, then clean the seat face so nothing is trapped under the new nozzle.
Keep the pair together
Keep the new nozzle and its own needle together — mixing a used needle with a new body loses the lapped fit and the spray pattern with it.
Torque to data
Fit the nozzle squarely and torque the retaining nut to the figure your workshop data gives for the injector in front of you.
Refit with seal and test
Refit the injector with a new seal ring and any single-use fasteners, write the calibration code the ECU requires, then check for leaks at idle before a road test.
A common rail injector nozzle replacement is normally done as part of an injector rebuild rather than in the vehicle. Because the nozzle is matched to the injector revision, a nozzle replacement should be confirmed against the injector number before the assembly goes back together. A slide-hammer injector puller is the usual tool for a unit that has seized in its seat, and the seat itself must be cleaned before the assembly goes back in.
Step-by-step notes and tooling photographs are collected on our injector installation guide. Torque values and clamp sequences are injector-specific; take them from your workshop data for the unit in front of you.
Nozzle replacement and nozzle holder notes
Most of the risk in this job sits in two places. The first is the seat: carbon left on the face the assembly clamps against holds it off its seal, and the leak shows up as a misfire long before it shows on any gauge. The second is the pairing. The needle belongs to the body it was lapped into, so an assembly built from a used needle and a new body will not hold pressure however carefully it is torqued down. Clean the recess in the fuel nozzle holder, keep the new pair together, and the two commonest comebacks on a bench rebuild are removed before they start.
Where an assembly has seized in its bore, do not lever it out against the spray face. Work it free with a puller, then check the bore for scoring before the new unit goes in. A scored bore will not be cured by renewing the nozzle alone, and in that case the whole assembly is the repair.
Reference and interchange numbers
Need a DLLA142P1595 cross reference or a DLLA142P1595 equivalent? The interchange numbers below are the ones buyers match against. All are reference interchanges only.
A bosch common rail nozzle, a bosch injector nozzle or a bosch nozzle from another family will not interchange with this article; the article listed as bosch dlla142p1595 is the one matched to the CRI2-16 injectors above. A nozzle interchange against 0445110435 or 0445117077 is safe only when the injector body itself carries that number, and 0986435165 is listed alongside them in the Bosch cross reference. These numbers identify the same article group; they are not a statement that this unit is an original-equipment part.
The injector assembly carries its own number and the table above deliberately stops at nozzle level. If your old unit is stamped with a number that does not appear here, send us a photograph of the injector number before ordering and we will check it against the CRI2-16 injectors.
Two suppliers can quote the same article under different wording — one listing a Bosch injector nozzle, another a nozzle for the CRI2-16 range, a third a short DLLA reference. None of those descriptions identifies the article on its own. The two fields that do are the trailing DLLA digits and the injector the unit is built for, which is why we record both on the offer we send.
Build quality and inspection
Every nozzle is built from precision-ground components and checked before it leaves us.
Every nozzle is built from precision-ground components: the needle is lapped into its body to the CRI2-16 architecture used by the F1AE0481 engine family, so the spray pattern matches the injector it was built for. The spray holes are formed and finished so the jets keep their angle across the service interval rather than widening as they wear in.
The internal numbers inside the assembly are rev-dependent: confirm by injector revision or by the injector number on the body before ordering, because one 2.3 platform can carry more than one nozzle 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 assembly can be run on a common rail injector tester with the new nozzle fitted and the report supplied with the order.
Alongside complete injector nozzles 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 nozzle kit rather than the nozzle on its own, the internal numbers are confirmed against the injector revision you send us.

2.000 kg gross per pack.
4 pcs.
Individual protective tube, wrap, carton sealed.
The 10 × 10 × 10 cm pack is sized for tubed nozzles, so a set for a four-cylinder rebuild ships as a compact carton rather than a stack of oversize boxes. The packaged shipping weight is 2.000 kg gross per pack, which includes the nozzles, the protective tubes 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 injector nozzle 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 a figure from another exporter, ask for it to include freight and the warranty terms so the comparison is like for like.
For a small rebuild batch 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.
