Product Information

Volkswagen Camshaft and Components diagram for A3, Beetle, Golf, Jetta, Passat

An engine camshaft is a rotating shaft inside an engine that controls the opening and closing of the intake and exhaust valves.

It has precisely shaped lobes (cams) that push on valve lifters, rocker arms, or cam followers, which in turn open the valves at specific times in the engine’s cycle. The camshaft’s timing is synchronized with the crankshaft via a timing belt, chain, or gears to ensure valves open and close in coordination with piston movement.

• Tapping, Ticking, or Popping Noises from the Engine: Worn lobes or damaged lifters can cause irregular valve operation.
• Poor Engine Performance / Power Loss: Incorrect valve timing or worn lobes reduces airflow and combustion efficiency.
• Misfires or Rough Idle: Valves may not open/close correctly, causing incomplete combustion.

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.
