DELPHI 28326855 Injector for MERCEDES-BENZ W204: Application Matching

The DELPHI 28326855 is listed for conditional catalogue applications for the MERCEDES-BENZ C-CLASS W204 with OM 651. The existing part reference, engine code and complete conditions relating to chassis number, production date and SA codes are decisive.

The DELPHI 28326855 is an injector with conditional catalogue applications for the MERCEDES-BENZ C-CLASS W204 with OM 651.

Component identification and confirmed reference numbers

DELPHI 28326855 identifies the manufacturer's reference for the injector covered here. METZGER AUTOTEILE 0871028 is recorded as an additional catalogue reference. Both references remain associated with their respective brands; the METZGER number is not a DELPHI part number.

The available references are not explicitly identified as OE or OEM numbers. Such a designation would therefore be unsupported. Selection depends on comparing the complete identification on the existing part with the manufacturer's reference and the specific vehicle application, not simply on matching individual digits.

The number 0871028 also serves as an internal search reference in the shop. This additional function makes it neither a DELPHI manufacturer reference nor a MERCEDES-BENZ OE number. For technical identification, 28326855 remains the definitive DELPHI reference.

Representative TecDoc selection for the C-CLASS W204

There are 94 verified TecDoc applications in total. The following table shows only the supplied representative selection for MERCEDES-BENZ, not the complete application list. The production periods describe the listed vehicle variants; they do not replace the more restrictive fitment conditions of the respective catalogue branches.

The letters assign the conditions below to the W204 variants. Within a branch, all conditions must be met together. The branches are alternatives; individual matching criteria from different branches must not be combined to establish fitment approval.

• Branch A: Chassis number from: 30997547 · Chassis number to: 31827005 · Production date from: 31.01.2012 · Production date to: 31.07.2013 · Vehicle production plant: 3 · Not for combined SA code: -70O-79O-064-A11.
• Branch B: Chassis number from: 30997547 · Production date from: 31.01.2012 · Production date to: 31.10.2012 · Vehicle production plant: 3 · For combined SA code: +M007+M013 · Not for combined SA code: -70O-79O-A11.
• Branch C: for SA code: B03 · Not for combined SA code: -70O-79O-064-A11.
• Branch D: Chassis number to: 31827005 · Production date to: 31.07.2013 · Vehicle production plant: 3 · Not for combined SA code: -70O-79O-064-A11.

The C 220 CDI 4-matic (204.084) therefore has a different selection of branches from the other table rows. The two power variants of the C 220 CDI (204.002) also remain separate entries. Model name and power output alone do not allow a definitive part selection.

Check fitment using the existing part, engine code and vehicle data

Before ordering the DELPHI 28326855, carry out a combined identification check. A matching engine code narrows down the application but confirms neither the equipment conditions nor the version of the existing injector.

1. Record the existing part identification: Document all legible part numbers and manufacturer details on the removed or accessible original component. Different references require a documented catalogue cross-check.
2. Establish the engine code: Distinguish precisely between OM 651.913, OM 651.911 and OM 651.912. The shared OM 651 engine family is not sufficient as a selection criterion.
3. Match the vehicle data: Compare the complete VIN, type designation, production date and production plant with the applicable table row and its branches. First registration and production date must not be treated as equivalent.
4. Check the equipment: Use the vehicle data to assess SA code B03 and the listed combined inclusion and exclusion criteria. A vehicle within the specified date range may fail to meet an equipment condition.
5. Compare the version: Compare the connector, body shape and markings of the existing part with the intended replacement. Visual similarity does not replace reference matching.

For a C 200 CDI (204.001) with OM 651.913, for example, not every branch has to be satisfied, but all conditions of at least one applicable branch must be met. Without complete vehicle data, the application remains unconfirmed; the table row is not a blanket fitment approval.

Assess symptoms and select the correct injector

Rough idling, starting problems or unusual combustion noises can generally justify checking the injection system. On a W204 with OM 651, however, these symptoms do not prove that the DELPHI injector is faulty. Fault memory, electrical actuation and fuel supply are part of a systematic diagnostic process.

A correctly performed leak-off test can indicate internal leakage; the assessment must be appropriate for the injection system concerned. This does not establish that 28326855 is the correct part. Fault diagnosis and replacement part selection answer different questions and must not be confused.

When selecting a part for the C 250 CDI or C 180 CDI, neither similar symptoms nor the shared model series are therefore sufficient. Only the combination of a documented reference match, the correct engine code and fulfilled catalogue conditions supports the decision to select a specific injector.

Find DELPHI 28326855 in the shop

The shop search for DELPHI 28326855 searches by the manufacturer's reference. For a technical application enquiry, the existing part number, engine code, VIN and production date should be available together; for the W204 applications listed, the relevant equipment data is also required.

The search reference 0871028 can help locate the listing. However, a search result or the recorded cross-reference number METZGER AUTOTEILE 0871028 replaces neither the check of the specific vehicle conditions nor the comparison with the existing component.
