Cómo comprar el inyector Bosch A6540700187 usado para Mercedes OM654

El inyector Bosch A6540700187 es compatible con una amplia gama de modelos Mercedes-Benz OM654 2.0d, incluidos el C220d, E220d y GLC. Esta guía te ayuda a identificarlo, cruzar referencias e inspeccionarlo antes de comprarlo de segunda mano.

What Is the Bosch Injector A6540700187 and Which Cars Use It?

The Bosch injector carrying Mercedes OEM number A6540700187 (Bosch part 0445117048) is a common-rail piezo or solenoid fuel injector designed specifically for the Mercedes-Benz OM654 2.0-litre diesel engine, introduced in 2016. This engine family powers a broad range of popular models:

C-Class W205 / W206 – C 200d, C 220d
E-Class W213 – E 200d, E 220d
GLC X253 – GLC 220d, GLC 250d
GLE V167 – GLE 300d
Sprinter / Vito – 2.0d OM654 variants

Because the OM654 is Mercedes' mainstream diesel across so many model lines, sourcing a tested used injector is a practical way to manage repair costs. You can view the part listed for sale on AutoParts EU or browse the wider fuel system category for related components.

How to Identify the Injector by OEM Number and Label

When inspecting a used injector, look for these identifiers:

Mercedes OEM stamped or labelled: A6540700187 or A 654 070 01 87
Bosch part number on the body: 0 445 117 048 or 0445117048
Bosch manufacturing label: typically a barcode sticker with both numbers on the injector body or connector housing

The part number format on the injector body may vary slightly depending on production batch, but both numbers should be traceable. Always compare what is physically printed on the part against the listing — do not rely on box markings alone for used parts.

Cross-Reference Numbers

This injector is commonly sold and referenced under several part numbers. Verify compatibility using your vehicle's VIN before ordering.

| Source | Part Number | |---|---| | Mercedes-Benz OEM | A6540700187 | | Mercedes-Benz alternative OEM | A6540700287 | | Bosch (primary) | 0445117048 | | Bosch (cross) | 0445116030 | | Bosch (cross) | 0445116031 |

Not all cross-reference numbers are direct drop-in replacements — some may apply to different OM654 variants or production periods. Confirm with the seller before purchasing.

What to Check Before Buying This Injector Used

Used injectors can be a cost-effective solution, but require careful vetting:

Injector coding number – OM654 injectors use an individual calibration code (IMA or C3I code). Ask the seller for this code; without it, the ECU cannot be programmed correctly.
Visual condition – Check the nozzle tip for carbon build-up, corrosion, or physical damage. Inspect the electrical connector for bent or corroded pins.
Sealing surfaces – Examine the copper sealing washer seat and the return line port for damage.
Provenance – Ask how many kilometres the donor vehicle had, and whether the injector was removed due to engine failure or a routine repair.
Testing – Ideally, ask whether the injector has been flow-tested or at minimum confirm it was running when removed.

FAQ

Will this injector fit my specific OM654 engine variant?

The A6540700187 is designed for the Mercedes OM654 2.0d family, covering the majority of C-Class, E-Class, GLC, GLE, and Sprinter/Vito applications built from 2016 onwards. However, always verify using your VIN or consult the seller, as production changes can affect fitment.

Do I need to recode the injector after fitting it used?

Yes. OM654 injectors require individual calibration codes to be programmed into the ECU using Mercedes XENTRY diagnostic software or compatible tools. Make sure you obtain the injector's code from the seller before fitting.

Is a used injector reliable enough for everyday use?

A properly tested and correctly installed used injector from a low-mileage donor vehicle can restore normal engine operation. Have it fitted and coded by a qualified diesel specialist to ensure correct installation and ongoing monitoring.
