Volkswagen Vacuum Hose - Genuine Volkswagen 1K0133778AG

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 Genuine VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

You may not realize this, but the parts that make up your VW are not necessarily manufactured by VW. No cause for concern, as VW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine VW parts box and find an OEM branded part inside, simply with the addition of a VW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
