Mercedes-Benz W204 W212 High Pressure Fuel Pump A27115004 - Used Original Parts
Diagnosis and Common Symptoms
In modern German direct injection engines, the high-pressure fuel pump (HPFP) is a critical mechanical component driven by the camshaft. When the internal plunger seals or the fuel volume control valve fail on this M271-era engine, the system loses the ability to maintain the required target rail pressure under load. Drivers will typically experience extended cranking times during cold starts, severe hesitation, engine misfires, and an immediate drop into limp mode to protect the catalytic converters. A prominent dashboard warning will be an illuminated Check Engine Light accompanied by common OBD2 fault codes such as P0087 (Fuel Rail/System Pressure Too Low), P0088 (Fuel Rail/System Pressure Too High), or P0191 (Fuel Rail Pressure Sensor Range/Performance). In severe cases of internal seal failure, fuel can bypass the pump housing and leak directly into the crankcase, causing a strong odor of gasoline in the engine oil—a condition that requires immediate repair to prevent catastrophic bearing failure.
Introduction
As a Senior Technician at M.S. Motor, I know firsthand that high-pressure fuel delivery components must meet strict factory specifications to avoid dangerous lean-burn conditions. This unit is a Genuine used high-pressure fuel pump that has been meticulously inspected and tested to ensure the internal regulator and mechanical plunger operate seamlessly under load. By choosing a verified Genuine replacement, you bypass the inconsistency of aftermarket alternatives and instantly restore precise direct injection pressure to your vehicle.

Frequently Asked Questions
Q: What symptoms indicate failure? A: The most frequent symptoms include long cranking times before engine startup, rough idling, hesitation or power loss under hard acceleration, and the vehicle entering limp mode. If you check your oil dipstick and smell unburned fuel, the internal seals of your pump have failed.
Q: Does this require coding? A: No. The high-pressure fuel pump is a mechanically driven component featuring an electronic volume control valve. It is entirely plug-and-play and does not require programming or SCN coding. However, clearing old fault codes and resetting engine adaptation values via a diagnostic scanner is strongly advised for optimal performance.
Q: Is this original? A: Yes. This is a Genuine Mercedes-Benz component salvaged from a running donor vehicle. It has been strictly pressure-tested to confirm it meets original factory operational standards.
