Mercedes Sprinter Diesel Fuel Injector – Bosch | VS30 2.0L OM654 Diesel | #6540700087 (2022–2025)

A failing fuel injector on a VS30 Sprinter delivers an incorrect fuel charge to its cylinder on every combustion event — causing a cylinder-specific misfire, rough idle, black smoke, and power loss that won't resolve until the injector is replaced and the injection system is recalibrated. This is the Bosch diesel fuel injector for VS30 Sprinters equipped with the 2.0L OM654 diesel engine, sold individually for targeted replacement or complete set renewal.

What This Part Does

The fuel injector is a solenoid-controlled precision valve that receives high-pressure diesel from the fuel rail and atomizes it into the combustion chamber in multiple precisely timed spray events per combustion cycle. On the OM654's 4th-generation common-rail system, operating at up to 2,700 bar of rail pressure, the injector fires in as many as five distinct events per cycle — a pilot injection, main injection, and post-injection phases — to control combustion noise, maximize thermal efficiency, and minimize particulate emissions. Each injector is coded to the ECU with an individual correction code that compensates for manufacturing tolerances in spray pattern and flow rate, ensuring consistent fuel delivery across all four cylinders. When an injector's tip erodes, its needle sticks, or its solenoid loses electrical response, fuel delivery on that cylinder becomes inconsistent — causing the cylinder to misfire, run rich, or fail to fire altogether.

Common Symptoms of a Failing Fuel Injector

• Rough idle or cylinder-specific misfire confirmed by scan tool misfire data
• Black smoke under acceleration from fuel-rich combustion on the affected cylinder
• Loss of power or uneven throttle response, particularly at low RPM
• Increased fuel consumption from incomplete or inefficient combustion
• Check engine light with injector-related fault codes or injection quantity deviation faults
• Hard starting, especially when cold, from injector leakage that floods or washes the cylinder

When to Replace

Replace when the injector is confirmed faulty by XENTRY with active injection deviation or misfire fault codes on a specific cylinder. When replacing a single injector, program the new injector's correction code into the ECU. Also replace as a complete set of four during a full injection system overhaul — mixing worn and new injectors creates cylinder-to-cylinder fuel imbalance. Always replace the high-pressure fuel filter when servicing injectors to protect the new injector from contamination.

VS30 OM654 Specific — VIN Verification Required

This injector is for VS30 Sprinters equipped with the 2.0L OM654 diesel engine. It is not compatible with VS30 models equipped with the 3.0L OM642 or NCV3 Sprinters equipped with the 2.1L OM651. Always verify your engine code and VIN before ordering. Contact us and we'll confirm fitment before you buy.
