BOSCH 0445110299 Fuel Injector for ALFA ROMEO, FIAT and OPEL

The BOSCH 0445110299 is a fuel injector with verified vehicle applications for ALFA ROMEO, FIAT, LANCIA, OPEL and SAAB. Selection requires cross-checking the original part number, engine code and exact vehicle details together.

The BOSCH 0445110299 is a fuel injector for selected JTDM, Multijet, CDTI and TTiD engines from ALFA ROMEO, FIAT, LANCIA, OPEL and SAAB.

Component identification and verified reference numbers

The definitive manufacturer reference is BOSCH 0445110299. The alternative format BOSCH 0 445 110 299 separates the same sequence of digits with spaces. When comparing it with the removed injector, the complete number is what counts; a partial match is not sufficient for part selection.

• Manufacturer: BOSCH.
• Component: Fuel injector for the listed engines.
• Primary part number: 0445110299.
• Other listed reference format: 0 445 110 299.
• Internal shop search reference: 0 445 110 299; this does not replace checking the manufacturer reference.

The references provided are not identified as vehicle manufacturer OE numbers. They must therefore not be interpreted as independent OE approval for a particular ALFA ROMEO, FIAT or OPEL. Listing several brands together also does not mean that every fuel injector within these model ranges is interchangeable.

Representative TecDoc vehicle applications

There are a total of 38 verified TecDoc applications for the BOSCH 0445110299. The following table shows a representative selection, not the complete compatibility list. It covers all the brands provided here and the specified 1.9 and 2.0 engine variants. Each date range relates to the listed vehicle entry and does not replace checking the individual vehicle.

For the LANCIA DELTA III, for example, the 1.9 D Multijet with 844 A1.000 and the 2.0 D Multijet with 844 A2.000 are listed alongside each other. The model name alone does not distinguish these applications. For the FIAT SEDICI, both the 2.0 D Multijet and the 2.0 D Multijet 4x4 are included; both listed entries specify D20AA and 135 metric hp.

Check fitment using the original part number, engine code and vehicle details

Identifying the correct application for fuel injector 0445110299 starts with the component actually fitted. A vehicle designation such as SAAB 9-3 or OPEL COMBO narrows the search but does not yet confirm a specific variant. For a reliable selection, the part markings, engine code and vehicle details must all match without discrepancies.

1. Record the original part markings: Read and document the complete manufacturer and part number on the removed injector. If the markings are illegible, do not order solely on the basis of visual similarity.
2. Cross-check the engine code: For example, compare 940 A5.000 for the listed GIULIETTA or A 19 DTR for the specified SAAB applications against the vehicle documentation or reliable vehicle identification.
3. Complete the vehicle details: Have the model, type, power output, production date range and vehicle identification number ready for the catalogue check. For the COMBO, the specified type designations are part of the identification process.
4. Check the physical design: Compare the electrical connection, connector shape, housing and line connections with the original part. This visual check supplements the number comparison but does not replace it.
5. Resolve discrepancies: If the original part carries a reference other than BOSCH 0445110299, its application must be checked separately. A replacement or superseding number not verified here must not be assumed.

The engine code 844 A2.000 appears in this selection for both the ALFA ROMEO BRERA and the LANCIA DELTA III. This shows why brand name and engine displacement are not sufficient selection criteria. Conversely, a matching engine code without matching part and vehicle details does not establish general interchangeability between models.

Assess symptoms and select the correct fuel injector

Rough idle, starting difficulties, excessive smoke or harsh combustion noise can generally indicate an injection fault. They do not prove that the BOSCH 0445110299 is defective. Fuel supply, electrical control and the engine's mechanical condition are also possible causes and must be included in the diagnosis.

Before replacement, evaluate stored fault codes, electrical connections and the test values specified for the vehicle. A correctly performed injector leak-off test can indicate internal leakage in an injector; its results must be assessed according to the relevant test procedure. A single abnormal correction value is not sufficient on its own to justify replacement.

For JTDM, Multijet, CDTI and TTiD, the sequence therefore remains clear: narrow down the cause of the fault, identify the original part and confirm the vehicle application. Whether an identification code must be entered or an adaptation carried out after installation must be checked against the relevant repair instructions. This procedure cannot be reliably determined from the part number alone.

The selection of the BOSCH 0445110299 is reliable when the manufacturer reference, engine code and specific vehicle variant match. This application information does not establish the scope of supply, component condition or whether seals are included; these details must be clarified separately before ordering.
