Injector part-number cross-reference

One physical injector often carries three or four numbers: a Bosch, Delphi, Denso or Continental number, an OEM number from Volkswagen, Mercedes-Benz, Renault, Ford or PSA, a service or exchange number, and a supersession. Buying from a “fits 2.0 TDI” list is how people get the wrong generation. This guide explains how the numbers are built, which one to read off the injector, and how to search for a new OEM part on IJECT.

Always start from the injector in your hand

The number engraved or laser-etched on the injector body is the only reliable starting point. The door-jamb sticker, the owner’s manual and a vehicle-registration lookup will only narrow the engine. The same engine code (for example a VW 2.0 TDI with code BKD, CBBB or CRT) has used more than one injector family. If the injector is already out, photograph every line of text on the body, including small codes on the solenoid and the data matrix or QR code.

Bosch: how 0445, 0433 and 0986 fit together

Most Bosch common-rail injectors in cars and light commercials are in the 0 445 family. Printed they appear as 0445110562, 0 445 110 562 or 0 445 110 562-…. Spaces and dashes do not change the part. The middle group roughly marks the generation (110, 115, 116, 117 and so on). A nearby number is not a substitute: 0445110562 and 0445110563 are different calibrations.

0433 numbers are typically unit injectors (Pumpe-Düse / UIS) used on Volkswagen, Volvo and some Mercedes engines, not common-rail. 0986 and many F 00R / F 00V numbers are service, kit or exchange identities. If you have both a 0445 and a 0986 on the same body, the 0445 (or the OEM number) is the one to order as a new part. Bosch also stamps a production date and a 10-character IMA code — that IMA code is unique to the injector and is what you enter into the ECU; it is not the part number.

Delphi, Denso and Continental / Siemens VDO

Delphi. Common numbers look like 28232251, 28229873, EJBR03301D or a Renault/Nissan/Ford OEM number (for example a R or 16 prefix such as 166001137R). Delphi systems are unforgiving of air in the fuel and of a weak low-pressure supply; if several Delphi injectors fail together, test the supply and the pump before blaming the injectors alone.
Denso. Often 095000-, 1465 or Toyota/Mazda/Nissan OEM numbers. The body usually carries both the Denso number and the vehicle-maker number. Quote both when you order.
Continental / Siemens VDO. Numbers such as 5WS…, 03L 130… or PSA/Ford codes. Piezo injectors in this family must not be treated as a Bosch solenoid equivalent, even when they fit the same engine outline.

OEM numbers and supersessions

Volkswagen Group uses numbers like 03L 130 277, 04L 130…, Mercedes-Benz A 646 070…, A 651 070…, Renault-Nissan an R suffix, Ford a 3M5Q or similar engineering number, PSA a 1980xx or 9678… style code. A later OEM number may supersede an earlier one and refer to the same Bosch or Delphi unit — or to a revised unit that also needs a different IMA procedure. When two numbers are claimed to be interchangeable, confirm it on the manufacturer’s supersession, not on a marketplace title.

Sets sold as “4x 0445110562” are four of the same new injector. They still each have their own IMA code; you code them one cylinder at a time.

How to search on IJECT

Open the injector catalogue and enter the number exactly as it is stamped, with or without spaces. If nothing comes up, try the Bosch/Delphi/Denso number and the OEM number separately, and drop any leading zeros only as a last resort (Bosch 0445 numbers should keep the leading zero). You can also email the photographs to info@iject.eu. The shop lists new genuine parts only; see New OEM versus remanufactured for why that matters, and How to recognise a faulty common-rail injector before you replace a part that may not be at fault.

Pumps and turbos follow the same rule: order by the number on the unit, not only by the car model. Catalogues: fuel pumps, turbos.

Cross-references on this page are explanatory. Always confirm interchange on the part in front of you and on the vehicle manufacturer’s data.

Frequently asked questions

The injector shows both 0445110562 and a Volkswagen 03L number. Which do I order?

Either can work if they genuinely belong to the same unit — many Bosch injectors carry both. Search IJECT for each number and compare the product. If only one is listed, use that one and mention the other in your order note so we can confirm.

Is 0445110562 the same as 0445110563?

No. A one-digit change in a Bosch 0445 number is a different calibration or a different application. Do not substitute neighbouring numbers.

What is the short code on the solenoid — is that the part number?

Usually not. Short codes, date stamps and IMA/QR strings identify the individual injector or the production batch. The part number is the longer Bosch, Delphi, Denso, Continental or OEM number. You will need the IMA/QR code later, when you write the new injector into the ECU.

Can I order by the vehicle registration or VIN alone?

A VIN helps, but on diesel engines it is not enough. The same model year can have two injector generations. The number on the injector, or a clear photograph, is what we need.

Do you also list pumps and turbos by part number?

Yes. Use the catalogues for fuel pumps and turbos, or email info@iject.eu with the number on the unit.
