Description
This Mercedes fuel rail pressure sensor is a genuine OEM electronic fuel system component for Mercedes vehicles. Primary OEM number A0041531528. It is designed to monitor pressure inside the fuel rail so the engine management system can maintain accurate fuel delivery and stable running.
Its job is to send a precise pressure signal to the ECU, helping control injection timing, fuel quantity, and overall rail pressure regulation. A properly working sensor supports smooth starting, consistent engine response, efficient combustion, and correct operation of the common rail fuel system.
Common signs of a faulty unit include hard starting, rough idle, hesitation under load, loss of power, irregular fuel pressure readings, limp mode, or engine warning lights related to fuel pressure control. When the signal becomes inaccurate or intermittent, the engine may struggle to meter fuel correctly.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number A0041531528 before ordering. Professional installation is recommended, and diagnostic checks after fitting are advised as part of proper fuel system service.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
