The BK2Q9K546AG fuel injector valve from Siemens/VDO is designed for precise fuel metering in the Common-Rail system. For selection, reference numbers, engine code letters and vehicle data must be matched against the old part.
1) Component identification: BK2Q9K546AG, Siemens/VDO and verified reference numbers
The fuel injector valve with part number BK2Q9K546AG is a Siemens/VDO injector for Common-Rail fuel metering. The reference number BK2Q9K546AG is the central assignment basis, because it defines the matching valve and metering characteristics for the injection process.
For the assignment, the comparison/cross-references from the catalog logic are relevant: A-A2C59517051 as well as FORD BK2Q-9K546-AG. These numbers serve as matching points when the old part has different spellings or internal supplier codes, but the functional unit is identical.
- Primary reference: BK2Q9K546AG
- Cross-references: A-A2C59517051, FORD BK2Q-9K546-AG
- Technical application: precise injection in the Common-Rail system
2) TecDoc compatibility: representative selection for 2.2 TDCi/2.0 BlueHDi/2.2 HDi
The following table shows a representative TecDoc selection for the reference BK2Q9K546AG. The complete compatibility list is extensive; the decisive factor remains matching via reference number, engine code letters and vehicle data.

This selection covers the engine families listed in the TecDoc extract (among others ENPF, AHM (DW10FUE), AHN (DW10FUD), 4HG (P22DTE), DT224(PUMA)). For the final decision, the reference BK2Q9K546AG must be checked on the old part and the vehicle data must match.
3) Fitment check: match old part reference, engine code and vehicle data against BK2Q9K546AG
The injector with BK2Q9K546AG is intended for precise fuel metering in the Common-Rail system. Exactly this metering function reacts sensitively to deviations, which is why the match must be carried out via the reference number and the vehicle/engine information before ordering.
Key points from the selection method: reference number on the old part, engine code letters and vehicle data. In practice, this means the assignment must not only be based on the model designation (e.g. Transit-near commercial vehicle families), but on the exact engine code from the TecDoc match.
- Match the reference number on the old part with BK2Q9K546AG
- Check engine code letters (e.g. ENPF, AHM (DW10FUE), AHN (DW10FUD), 4HG (P22DTE)) against the vehicle data
- Use cross-references as spelling/supplier codes: A-A2C59517051 and FORD BK2Q-9K546-AG
Using the cross-references is particularly helpful when the old part has a different notation, but the same assignment exists in the catalog system. For safe selection, however, the reference BK2Q9K546AG remains the benchmark.
4) Typical symptoms and selection notes for Common-Rail fuel injector valves
A fuel injector valve directly affects combustion quality, cold-start behavior, engine running, fuel consumption and power delivery. If there are deviations in pressure, injection quantity or spray pattern, noticeable problems occur during operation because the fuel metering no longer matches the target values exactly.
The reference BK2Q9K546AG is designed as a fuel injector for highly precise injection in the Common-Rail system. That is exactly why selection should be based on reference number and engine data, not purely on the vehicle model.
- Unstable engine running and unstable combustion due to deviations in injection quantity or spray pattern
- Poorer cold-start behavior with incorrect fuel metering
- Power delivery and fuel consumption affected if the metering characteristic does not match the system
When deciding on the part, the combination of BK2Q9K546AG and the correct vehicle/engine information remains decisive. Cross-references like A-A2C59517051 and FORD BK2Q-9K546-AG support the matching process, but do not replace checking the old part.
5) Matching fuel injector valve BK2Q9K546AG: product page and part number in detail
For ordering and TecDoc matching of the reference BK2Q9K546AG as a fuel injector valve, the product page leads directly to the correct unit: Fuel injector valve BK2Q9K546AG (Siemens/VDO) for Ford Transit, Peugeot Boxer, Citroen Jumper. There, the assignment can be traced via the TecDoc compatibility data and the vehicle widget based on the reference BK2Q9K546AG.
The cross-references A-A2C59517051 and FORD BK2Q-9K546-AG can help when matching the old part details if the spelling in the vehicle documents or on the component differs.
Frequently Asked Questions
What is the meaning of the reference number BK2Q9K546AG for the fuel injector valve?
The reference number BK2Q9K546AG is the central assignment basis for the correct fuel injector in the Common-Rail system. It determines the design for precise fuel metering. Cross-references such as A-A2C59517051 or FORD BK2Q-9K546-AG support the matching process, but do not replace matching on the old part.
Which engine codes fit BK2Q9K546AG for Ford Ranger and Peugeot Boxer?
In the TecDoc extract, among others ENPF and GBVAJPF are listed for Ford Ranger 2.2 TDCi, as well as AHM (DW10FUE) and AHN (DW10FUD) for Peugeot Boxer 2.0 BlueHDi. The selection must be verified against the old part via reference number, engine code letters and vehicle data, because the complete list contains more variants.
How do I recognize a defective Common-Rail fuel injector valve BK2Q9K546AG?
Typical signs are problems with combustion quality, cold-start behavior and engine running. If injection quantity or spray pattern no longer matches the target values, this also affects fuel consumption and power delivery. However, the exact cause must be confirmed through part assignment and system testing.
Can BK2Q9K546AG also be replaced via A-A2C59517051 or FORD BK2Q-9K546-AG?
A-A2C59517051 and FORD BK2Q-9K546-AG are cross-references that serve as matching points in the catalog system. The decisive factor is that the old part and the vehicle data match the reference BK2Q9K546AG. A 1:1 replacement should only be done after exact reference and engine code matching.
Must the engine code be checked before buying BK2Q9K546AG?
Yes. The selection method requires matching the reference number, the OEM/assignment information (if available) as well as the engine code letters and vehicle data against the old part. Only then can it be ensured that the fuel injector in the Common-Rail system correctly matches the engine variant.
