Audi Vacuum Pump Hose - VNE 078133701AD

Product Information

A Vacuum Hose is a flexible rubber or plastic tube in a vehicle that carries vacuum (negative air pressure) from the intake manifold or vacuum pump to various engine components. Many automotive systems rely on engine vacuum for proper operation, including the brake booster, emissions controls, fuel pressure regulator, and HVAC controls.

• Rough idle or stalling – unmetered air entering the engine disrupts the fuel-air mixture.
• Hissing noise under the hood – sound of air leaking from a broken or loose hose.
• Poor acceleration / loss of power – incorrect air-fuel ratio affects combustion.
• Check Engine Light (CEL) – often triggered by lean condition codes (P0171, P0174).

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.
