The Audi A6 catalytic converter is part of your car's exhaust system. Your A6 catalytic converter resides in an enlarged portion of your exhaust pipe. Specifically, the Audi A6 catalytic converter is a honeycomb filter that contains a small amount of precious metals, usually platinum, palladium, and rhodium.

The purpose of the A6 catalytic converter is to remove harmful pollutants from your engine's exhaust before it exits your car through the tailpipe. To accomplish this, the Audi A6 catalytic converter creates a chemical reaction, using the metals it contains, to break apart toxic emissions molecules and re-form them into safe molecules of carbon dioxide and water vapor.

Without a working A6 catalytic converter, your car will not only fail its emissions test, you will also be releasing harmful vapors into the environment—and sometimes into your cabin. Unfortunately, it is often difficult to tell when you have a faulty Audi A6 catalytic converter. A rotten-egg smell in your exhaust can sometimes indicate a bad A6 catalytic converter, or it may be discovered during an emissions test. If your exhaust symptom clamps break or rust out and your muffler ends up dragging on the road, you may also damage your Audi A6 catalytic converter.
