The Bosch 0445110800 is an injector for selected DACIA and RENAULT applications with 1.5 dCi or Blue dCi engines. Correct identification requires checking the old part number, K9K engine code and exact vehicle variant together.
The Bosch 0445110800 is an injector for selected DACIA and RENAULT models in the 1.5 dCi or Blue dCi engine family.
Component identification and confirmed reference numbers
The definitive manufacturer reference is Bosch 0445110800. This complete number is what matters when selecting a replacement part, not simply the description “injector for 1.5 dCi”. The available applications cover different K9K engine codes, power outputs and vehicle variants. A similar model designation therefore does not replace a part-number comparison.
- Manufacturer and part number: Bosch 0445110800.
- Component: Injector for selected 1.5 dCi and Blue dCi applications.
- Internal search reference: Dieselfixneuss DFN-445110800.
The reference Dieselfixneuss DFN-445110800 is used solely to identify the shop item. It is neither a Bosch manufacturer part number nor a vehicle manufacturer OE number. The available information does not include any confirmed OE numbers. Comparisons with other suppliers’ listings must therefore use the stated Bosch reference and the specific vehicle application.
Representative TecDoc vehicle applications for DACIA and RENAULT
A total of 32 TecDoc applications are confirmed for injector 0445110800. The following table shows a representative selection, not the complete application list. It covers both brands and all supplied engine/type variants. The power figures remain unchanged: variants with “115” in their designation are also listed here with 116 metric hp.

An open end date in these DACIA and RENAULT applications confirms neither unrestricted compatibility up to the present nor suitability for every vehicle from the stated start date. The exact type variant, engine code and vehicle-specific parts check remain decisive.
Check compatibility using the old part, engine code and vehicle data
- Record the old part markings: Clean the existing injector without damaging its markings and read all part numbers in full. The number 0445110800 must be compared exactly; a few matching digits are not enough.
- Identify the complete engine code: “K9K” alone is too imprecise. The selection includes, for example, K9K 872, K9K 873 and, for the DUSTER 4x4, K9K 878 or K9K 874. The complete code must be included in the check.
- Cross-check the vehicle data: Use the vehicle identification number, model, type variant, power output and production date together. The MEGANE IV Hatchback and Grandtour are listed separately; the drivetrain variant must also be considered for the DUSTER.
- Check the physical design: Compare the electrical connector, housing shape and visible markings on the old part with the intended Bosch injector. Visual similarity does not confirm technical interchangeability.
If the old part number differs from Bosch 0445110800, a reliable cross-reference is required. A matching K9K code or an identical year of manufacture is not sufficient on its own. If the markings are illegible, the selection must be verified using vehicle data and an unambiguous catalogue check, rather than inferring a number from a similar housing.
Assess symptoms and verify the replacement part selection
Rough idling, starting difficulties, smoke or unusual combustion noise can indicate faulty injection. None of these symptoms proves that the Bosch 0445110800 is defective. Before replacement, the fault memory, fuel supply and affected cylinders must be checked systematically.
On a 1.5 dCi, comparative leak-off measurements and analysis of smooth-running correction values can help narrow down the cause. Individual correction values do not, however, provide a definitive injector diagnosis. Electrical wiring faults or mechanical problems can also affect combustion; the assessment must match the specific fault symptoms.
Selecting the injector and establishing the fault are separate tasks. A confirmed vehicle application for 0445110800 says nothing about the condition of the removed component. If the fuel system is contaminated, the cause must be established before installation so that the replacement part is not exposed to the same conditions.
Find the Bosch injector in the shop
The internal search for Bosch 0445110800 searches using the manufacturer reference. DFN-445110800 can also be used for enquiries about the associated item. An enquiry should include the number read from the old part, the complete K9K engine code and the vehicle data.
Before ordering the Bosch injector, the part-number comparison and vehicle check must agree. The designation “DACIA/RENAULT 1.5 dCi” narrows down the application but does not replace unambiguous part identification. If the old part, engine code and catalogue entry do not agree, the application must be clarified first.
Frequently Asked Questions
Which vehicles does the Bosch 0445110800 injector fit?
The confirmed selection covers certain DACIA SANDERO II and DUSTER models, as well as RENAULT KADJAR and MEGANE IV models with 1.5 dCi or Blue dCi engines. There are 32 TecDoc applications in total; the table shows only a selection. Exact suitability must be checked using the part number, complete engine code and vehicle data.
Does the Bosch 0445110800 fit every K9K engine?
No, the K9K designation alone is not sufficient for part selection. The listed applications differ by complete engine codes such as K9K 872, K9K 873 or K9K 878. The vehicle variant and old part number must also match the application.
Is DFN-445110800 a Bosch part number?
DFN-445110800 is an internal search reference used by Dieselfixneuss. The manufacturer reference is Bosch 0445110800. The DFN number is not a vehicle manufacturer OE number.
What symptoms suggest a faulty injector on the 1.5 dCi?
Possible signs include rough idling, starting difficulties, smoke and unusual combustion noise. These symptoms cannot be attributed conclusively to an injector. Fault memory checks, fuel supply checks and suitable comparative measurements must substantiate the suspicion before replacement.
