Based on data from over 1,000,000 Mercedes-Benz Sprinter B903/B904 vehicles worldwide equipped with the 647981 (2.7D) engine, these vehicles generally experience a high incidence of fuel injection system failures after 100,000 kilometers or five years of use.

Are you troubled by these problems?

The engine lacks power, and the accelerator response is sluggish.  

The vehicle struggles on inclines, as the torque output fails to meet the demands of operating conditions.

Black smoke emits from the exhaust pipe, indicating incomplete fuel combustion.

The significant increase in fuel consumption poses a risk of failing environmental inspections.

Why does a fuel injector fail?

It has long been exposed to high temperature and pressure, resulting in engine overheating.

The fuel injection pressure is too low, causing combustion gas to backflow into the combustion chamber.

Impurities in the diesel fuel cause the internal needle valve to stick.

Dirt and carbon deposits in the diesel engine lead to nozzle clogging.

FAQ

Question: Is it okay to replace only one of the four fuel injectors on the same vehicle?
It is recommended to replace the fuel injectors of a coaxial engine in pairs or as a complete set to ensure consistent fuel delivery across all cylinders and avoid engine vibration or power imbalance caused by differences between new and old injectors. For commercial vehicles such as Sprinter, replacing all fuel injectors is more conducive to ensuring long-term operational stability.
