Volkswagen Engine Timing Sprocket - Genuine VW 03H109570N

Product Information

Volkswagen Timing diagram for Atlas, Atlas Cross Sport

An engine timing sprocket is a toothed wheel mounted on the crankshaft or camshaft that engages with a timing chain or belt to synchronize the rotation of the engine’s valves and pistons. This precise timing ensures efficient combustion, smooth power delivery, and prevents internal engine damage. A properly functioning sprocket is essential for maintaining correct valve timing and overall engine performance.

• Rattling or knocking noises from the timing area, often due to worn sprocket teeth.
• Engine misfires or poor performance, caused by incorrect valve timing.
• Complete engine failure to start, if the sprocket slips or fails to engage properly.

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.
