Audi VW Engine Camshaft Seal - Genuine VW Audi 03H109091

Product Information

A camshaft seal is a rubber or silicone ring located on the top of the cylinder head near the back of the engine, designed to prevent engine oil from leaking out; a failing camshaft seal will most noticeably manifest as visible oil leaks around the back of the engine, sometimes accompanied by smoke from the engine bay when the leaking oil comes into contact with hot exhaust components

• Visible oil leaks: The most obvious sign, usually seen on the back of the engine near the valve cover.
• Smoke from the engine bay: Oil leaking onto hot exhaust manifolds can burn off, producing smoke.
• Oil residue on the engine: Even small leaks can leave noticeable oil stains on the engine.

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.
