VW Engine Rocker Arm - Genuine VW 7B0109442

Product Information

An Engine Rocker Arm is a critical component in the valve train of an internal combustion engine. It acts as a lever that transfers the camshaft’s rotational motion into the up-and-down motion needed to open and close the intake and exhaust valves.

When the camshaft lobe pushes one side of the rocker arm, the other side presses down on the valve stem, allowing air-fuel mixture in (intake valve) or exhaust gases out (exhaust valve).

• Tapping or clicking noise from the engine – caused by excessive clearance or a loose/broken rocker arm.
• Engine misfire or rough idle – valves may not open properly, leading to incomplete combustion.
• Loss of power/poor acceleration – improper valve timing reduces engine efficiency.

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.
