BOSCH 0 445 110 419 Injector for ALFA ROMEO/FIAT/OPEL

The BOSCH 0 445 110 419 injector is assigned to selected ALFA ROMEO, FIAT and OPEL applications with 2.0-litre engines. There are 16 verified TecDoc applications in total; selection requires checking the original part number, engine code and vehicle data.

The BOSCH 0 445 110 419 injector is assigned to selected 2.0-litre applications in the JTDM, JTD, Multijet and CDTI engine families used by ALFA ROMEO, FIAT and OPEL.

Component identification and verified reference number

BOSCH 0 445 110 419 identifies the injector covered here. The same number is listed as both the primary article number and the catalogue reference. No additional cross-reference numbers or explicitly identified OE references are available for this article. Repeated use of the same reference therefore establishes neither an additional replacement variant nor approval for another vehicle application.

For searches in the multilingual European catalogue, the terms 0 445 110 419 injector and 0 445 110 419 Injector refer to the same number-based search target. The complete BOSCH part number remains decisive. A similar sequence of digits, a matching brand name or a visually comparable injector is not sufficient for identification.

Distinguishing between the article number and the vehicle application prevents incorrect orders: 0 445 110 419 identifies the component, while the TecDoc entry describes the corresponding vehicle application. Without additional evidence, the catalogue reference must not be described as the vehicle manufacturer's OE number. Nor can interchangeability with other BOSCH numbers be inferred from it.

Representative TecDoc vehicle applications for ALFA ROMEO, FIAT and OPEL

There are 16 verified TecDoc applications for this injector in total. The following table shows the supplied representative selection, not the complete compatibility list. It covers ALFA ROMEO GIULIETTA, FIAT FREEMONT, DOBLO and DUCATO, and OPEL COMBO with the specified engine and type designations.

A search for BOSCH 0 445 110 419 ALFA or ALFA injector 0 445 110 419 leads to the GIULIETTA (940_) 2.0 JTDM in this selection. The two listed groups of type codes must be considered separately. The shared model name does not establish a blanket application for every GIULIETTA engine variant.

For BOSCH 0 445 110 419 FIAT or FIAT injector 0 445 110 419, the selection covers several vehicle families. FREEMONT 2.0 JTD and 2.0 JTD 4x4 are listed alongside DOBLO 2.0 D Multijet and DUCATO 115 Multijet 2.0 D. The same engine displacement does not replace checking the engine variant or distinguishing between the model series and drivetrain configuration.

The search terms BOSCH 0 445 110 419 OPEL and OPEL injector 0 445 110 419 refer here to the COMBO (X12) 2.0 CDTI. Van/MPV and Tour have different type codes. These entries do not permit the application to be extended to other OPEL model series or all COMBO variants.

Fitment checks and installation preparation

Whether BOSCH 0 445 110 419 is compatible with a specific vehicle is checked using several matching characteristics. The table helps narrow down the selection; the final selection requires the complete vehicle data set. The listed GIULIETTA and COMBO type codes do not replace the engine code, which must be checked separately on the vehicle or in its documentation.

1. Identify the original part: Read the existing BOSCH part number in full and compare it with 0 445 110 419. Illegible markings must not be filled in by guesswork.
2. Check the engine code: Identify the specific engine variant and check it against the detailed catalogue application; JTDM, JTD, Multijet or CDTI alone is not sufficient.
3. Match the vehicle data: Use the vehicle identification number, model series, variant and available production data. For the FREEMONT, the distinction between 2.0 JTD and 2.0 JTD 4x4 is particularly relevant.
4. Compare the physical configuration: Check the electrical connector, housing shape and existing markings on the original part. A visible match supports the part number comparison but does not replace it.

For BOSCH 0 445 110 419 installation, the repair instructions for the specific vehicle and engine variant then apply. These include the treatment of sealing surfaces, fastening requirements and any prescribed testing or adaptation steps. Tightening torques, coding requirements or supplied installation parts cannot be inferred from the part number alone.

When working on the fuel system of the DUCATO, FREEMONT or COMBO, open connections must be protected against dirt ingress. Before removal, system pressure must be relieved according to the manufacturer's instructions. Installation and the subsequent leak check do not replace diagnosis of the original fault.

Symptoms and technical selection guidance

Rough running, difficult starting or abnormal smoke production can indicate an injection fault in JTDM, JTD, Multijet and CDTI applications. These symptoms do not, however, prove that the injector is defective. Fuel supply, electrical actuation and the mechanical condition of the engine must also be considered during fault diagnosis.

Before replacement with BOSCH 0 445 110 419, stored fault codes, operating conditions and appropriate measured values must be assessed together. A leak-off test can indicate internal leakage where specified by the manufacturer; abnormal correction values alone do not provide a reliable component diagnosis. Assessment requires the test conditions and limits applicable to the engine variant.

When ordering an injector for GIULIETTA, DOBLO or COMBO, two separate decisions must therefore be made: is the existing injector actually faulty, and is the replacement number assigned to the specific vehicle? A symptom does not determine the part number. If the original part markings or vehicle data conflict, the application must be clarified before ordering.
