VW Audi Catalytic Converter (Passat) - Genuine VW Audi 8E0131089DX

Product Information

A catalytic converter is an emissions-control device in a vehicle’s exhaust system that reduces harmful gases produced during combustion. It uses a ceramic or metallic honeycomb coated with precious metals like platinum, palladium, and rhodium to trigger chemical reactions that convert Carbon monoxide, Hydrocarbons, and Nitrogen oxides to water vapor and oxygen.

• Check Engine Light: Often triggered by oxygen sensor readings that indicate inefficient emissions conversion.
• Reduced Engine Performance: A clogged converter restricts exhaust flow, causing loss of power, sluggish acceleration, or difficulty maintaining speed.
• Rattling Noise from Under the Car: The internal honeycomb can break apart, creating a metallic rattling sound, especially when starting the engine or accelerating.

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.
