Audi VW Camshaft Follower - Genuine VW 050109309H

Product Information

An Engine Camshaft Follower (also known as a lifter or tappet) is a small component in an internal combustion engine that sits between the camshaft and the valves. Its role is to follow the camshaft’s rotation, translating the cam’s rotational movement into the up-and-down movement that opens and closes the engine’s valves. This enables air-fuel intake and exhaust gas release, which is essential for engine operation.

• Tapping or Clicking Noise: A worn or damaged camshaft follower can cause a distinct tapping or clicking sound from the top of the engine, which is often louder when the engine is cold
• Excessive Valve Clearance: Camshaft followers that have excessive wear can cause increased clearance in the valve train, which can lead to delayed or incomplete valve opening and closing

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.
