Checking the BOSCH 0445116012 injector for CITROËN and JAGUAR

The BOSCH 0445116012 is an injector for selected 3.0-litre applications from CITROËN, JAGUAR, LAND ROVER and PEUGEOT. The original part number, engine code and vehicle data are decisive for identifying the correct application; the representative TecDoc selection does not replace this cross-check.

The BOSCH 0445116012 is an injector for selected 3.0-litre engines in the DT20C, 306DT(AJTDV6) and 306DT(TDV6) families used by CITROËN, JAGUAR, LAND ROVER and PEUGEOT.

Component identification and verified reference numbers

The definitive manufacturer reference is BOSCH 0445116012. When selecting the part, this number must always be considered together with the manufacturer. A model designation such as JAGUAR XF I or CITROËN C5 III narrows down the application but does not identify the required injector on its own.

• BOSCH 0445116012: primary manufacturer reference for the component covered here.
• BOSCH 0 445 116 012: corresponding catalogue reference written with spaces.
• BOSCH 0 445 116 013: listed related catalogue reference whose interchangeability must be checked separately for the specific vehicle.

The reference BOSCH 0 445 116 013 is not blanket approval for replacement with 0445116012. A neighbouring number can help with research; however, the confirmed application must match the original part marking and the specific vehicle. The numbers listed are manufacturer or catalogue references, not vehicle manufacturer OE numbers verified here.

Representative TecDoc vehicle applications

A total of 23 verified TecDoc applications are available. The following table is a representative selection, not a complete compatibility list. It covers all four represented brands and the specified variants with DT20C, 306DT(AJTDV6) and 306DT(TDV6). The date ranges refer to the listed vehicle variants and do not replace a vehicle-specific part check.

For the JAGUAR XF I (X250), three power outputs are listed within the same model and engine code family. For the RANGE ROVER SPORT I (L320), the listed variants also have different starting months. Neither “3.0 D” nor a matching production year is therefore sufficient on its own as a basis for ordering. No end date is specified for the PEUGEOT 407 Coupe; this does not imply unrestricted approval.

Checking fitment using the original part number, engine code and vehicle data

Before ordering injector 0445116012, the marking on the removed component and the vehicle identification should be checked together. An engine code such as DT20C is a reliable search key, but it does not replace matching the numbers. Particularly on vehicles that have already been repaired, any differing original part marking must also be clarified.

1. Read the original part marking: Record the BOSCH marking and complete part number. Do not compare only the final digits or fill in a hard-to-read final digit based on the model designation.
2. Confirm the engine code: Identify DT20C, 306DT(AJTDV6) or 306DT(TDV6) using reliable vehicle documentation or the engine identification. Take the complete designation, including the suffix, into account.
3. Cross-check the vehicle data: Check the vehicle identification number, model, type, power output and production period together. On the C5 III, for example, RD_ and RW_ refer to different body variants.
4. Compare the physical design: Compare the electrical connector, housing shape and connection layout with the original part. A similar external shape does not confirm that BOSCH references are interchangeable.
5. Resolve discrepancies: If the original part carries a different number, its correspondence to 0445116012 must be confirmed on a traceable basis before ordering. A related catalogue reference alone is not sufficient.

For a C6 with DT20C and 241 PS, the table therefore provides a specific preliminary selection. The final decision can only be made after cross-checking the complete vehicle data and the original part reference. The same procedure applies to LAND ROVER applications with 306DT(TDV6); a shared engine family does not eliminate differences between vehicle variants.

Assessing symptoms and selecting the correct injector

Rough idle, difficult starting or unusual smoke can generally be reasons to inspect the injection system. However, these symptoms do not prove that the BOSCH 0445116012 is faulty. Nor are they criteria for selecting the replacement part number: diagnosis and part identification remain two separate tasks.

• Rough running: Evaluate stored fault codes and cylinder-specific measured values under defined test conditions. An abnormal smooth-running correction alone is not conclusive evidence of a faulty injector.
• Starting problems: Check the fuel supply, pressure build-up and electrical actuation before identifying an injector as the cause.
• Smoke: Assess injection and air supply together. Smoke colour alone does not allow a reliable decision about the component.
• Suspected contamination: Inspect the fuel system and investigate possible contaminants. Replacing a component does not eliminate a fault source that remains in the system.

Once an injector fault has been confirmed, the BOSCH 0445116012 is selected by reference and vehicle application, not by the symptoms. Installation requirements, sealing points and any necessary adaptations must then be checked against the vehicle-specific repair documentation. Neither tightening torques nor the required scope of work can be determined from the part number alone.
