Audi VW Fuel Injection Pressure Regulator - VNE 4007B04

Product Information

The Fuel Injection Pressure Regulator is a critical component of the fuel delivery system that maintains consistent fuel pressure to the injectors. It adjusts fuel flow based on engine demand by regulating excess fuel back to the fuel tank, ensuring optimal air-fuel mixture for efficient combustion. Typically mounted on the fuel rail or integrated within the fuel pump assembly, it helps improve engine performance, fuel efficiency, and emissions control.

• Poor Engine Performance – Loss of power, hesitation, or rough acceleration
• Hard Starting or No Start – Insufficient or excessive fuel pressure affecting ignition
• Engine Misfires or Rough Idle – Irregular fuel delivery disrupting combustion
• Decreased Fuel Efficiency – Excess fuel consumption due to improper pressure regulation
• Black Smoke from Exhaust – Rich fuel mixture caused by excessive fuel pressure
• Fuel Leaks or Fuel Odor – Possible diaphragm failure allowing fuel to escape
• Check Engine Light (CEL) – Triggered by abnormal fuel pressure readings

About VNE

VNE GmbH was founded in 2001 by Volker Natorp in Hamburg, Germany. Volker has a long, storied history in the automotive field. He began his career in the 1970s working for Wulf Gaertner and in the 1990s eventually branched out on his own to start his own sales repping agency. During that time, he represented TMD Friction (Pagid/Textar) and managed all of the North American sales for them and eventually added Schaeffler Automotive to his roster.

In 2007, VNE GmbH relocated to Ganderkesee, Germany and was renamed VNE Automotive GmbH & Co. With continuous growth, the decision was made to solely focus on developing VNE Automotive and, in 2014, the focus became reality with the commissioning of a new warehouse and office space. Today, VNE Automotive prides itself on never having followed the aftermarket trend. VNE Automotive operates in a highly specialized, niche product sector, by only offering OEM automotive spare parts to more than 50 countries worldwide. This is evident from the unique, and sometimes hard to find, product groups spanning engine management, body electrical, and brake systems.
