VW Audi Vacuum Pump (Passat Touareg Q7) - Genuine VW Audi 03H145100B

Product Information

A vacuum pump is a component that generates the necessary vacuum pressure for various vehicle systems, such as the brake booster, turbocharger controls, and emissions equipment. It is especially important in modern engines, including turbocharged and diesel engines, where natural engine vacuum may be insufficient. A properly functioning vacuum pump ensures safe braking performance and reliable operation of vacuum-dependent systems.

• Hard or stiff brake pedal, due to insufficient vacuum supply to the brake booster.
• Poor engine performance, affecting systems like turbo or emissions controls.
• Oil leaks or unusual noises from the pump, indicating internal wear or damage.

About Genuine VW Audi

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 VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

You may not realize this, but the parts that make up your VAG are not necessarily manufactured by VAG. No cause for concern, as VAG designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VAG 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 VAG parts box and find an OEM branded part inside, simply with the addition of a VAG logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct 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.
