Wie man OEM A6540700300 kauft: Bosch Einspritzdüsen-Ratgeber
Die Bosch Einspritzdüse A6540700300 passt in den Mercedes OM654 2.0d Motor, der im C220d, E220d, GLC220d und Sprinter verbaut ist. Dieser Ratgeber hilft Ihnen, eine gebrauchte Einspritzdüse zu identifizieren, zu referenzieren und zu prüfen, bevor Sie sie kaufen.
What Is the A6540700300 Injector and Which Cars Use It?
The Bosch A6540700300 (also catalogued as 0445118034) is a common-rail piezoelectric fuel injector designed for the Mercedes-Benz OM654 2.0-litre diesel engine. This engine family powers a wide range of post-2015 Mercedes models, making used injectors relatively accessible on the second-hand market.
Compatible vehicles include:
- Mercedes-Benz C 220 d (W205) – 2015–2021
- Mercedes-Benz E 220 d (W213) – 2016–2021
- Mercedes-Benz GLC 220 d (X253) – 2015–2021
- Mercedes-Benz GLE 300 d (W167) – 2019–2021
- Mercedes-Benz Sprinter (OM654 2.0d)
If your car has a rough idle, extended cold-start cranking, visible black smoke, or a diagnostic fault pointing to injector delivery deviation, this part is worth inspecting. You can view the specific unit for sale at AutoParts EU – Bosch Injector A6540700300 / 0445118034.
How to Identify It: OEM Number and Label Markings
The Mercedes OEM number A6540700300 is stamped or printed on a label affixed to the injector body. You will also see the Bosch part number 0445118034 printed on the same label alongside a barcode. The calibration code (IMA or C3I code) is laser-etched into the injector body near the electrical connector — this six- or seven-character code is needed when programming the injector into the ECU after fitting.
Always photograph the IMA code before purchasing or removing an injector; without it, accurate fuelling calibration is impossible.
Cross-Reference Numbers
The injector is sold and listed under several equivalent part numbers:
| Reference | Source | |---|---| | A6540700300 | Mercedes-Benz OEM | | 0445118034 | Bosch | | 0445116030 | Bosch alternate listing | | A6540700087 | Mercedes-Benz superseded | | A6540700188 | Mercedes-Benz superseded | | F00VP0B519 | Bosch service kit reference |
If searching for this part online or in catalogues, any of these numbers should return the same unit for the OM654 engine family.
What to Check Before Buying Used
Buying a used fuel injector carries specific risks. Here is what to verify:
- IMA/C3I calibration code is legible. This code must be entered into Mercedes XENTRY or equivalent diagnostics. A worn or illegible code makes the injector unusable.
- No physical damage to the nozzle tip. Even minor corrosion or scoring on the sealing cone will cause a compression leak or poor spray pattern.
- Electrical connector condition. The piezoelectric connector pins should be straight and free of corrosion.
- Ask about removal mileage. Injectors from lower-mileage engines or those removed due to non-injection faults (e.g., engine swap) are preferable.
- Confirm the exact OEM number matches. Do not substitute injectors across different OM654 variants without verifying the number — delivery rates differ.

FAQ
Does the A6540700300 fit all OM654 variants?
It fits the standard OM654 2.0d versions used in the C220d, E220d, GLC220d, GLE300d, and Sprinter. Always match the full OEM number on your existing injector before ordering, as other OM654 power outputs may use a different calibration.
Do I need to program a used injector after fitting?
Yes. The IMA calibration code etched on the injector body must be entered into the engine ECU using Mercedes XENTRY or compatible software. Skipping this step will result in incorrect fuel delivery and stored fault codes.
Can I replace just one injector, or do all four need changing?
You can replace a single faulty injector. However, if mileage is high and diagnostics show multiple injectors drifting out of tolerance, replacing all four at once reduces the risk of repeat labour costs.
