Mercedes-Benz W246 Fuel Pump Assembly A2465400617 - Used Original Parts

Diagnosis and Common Symptoms

A failing fuel delivery unit on the W246 B-Class typically triggers fault codes such as P0087 (Fuel Rail Pressure Too Low), P0230 (Fuel Pump Primary Circuit), or P0193 (Fuel Rail Pressure Sensor Circuit High). Drivers commonly report a whining noise from the rear of the vehicle that grows louder over time, sudden loss of power under acceleration, hesitation at highway speed, and difficulty starting after refueling. In advanced stages, the engine may stall intermittently, illuminate the Check Engine Light, and enter limp mode to protect the catalytic converter and injectors from fuel starvation.

Introduction

This is a Genuine Used fuel pump assembly (A2465400617) removed from an actual W246 donor vehicle, not an aftermarket copy. Every unit passes bench Tested procedures to confirm consistent pressure output and electrical continuity before listing. Since Mercedes-Benz fuel systems are pressure and calibration-sensitive, sourcing a Genuine module avoids the fitment and reliability issues common with generic replacements. Buyers get a direct, plug-and-play swap without altering factory fuel trim behavior.
