Rattling sound under the automobile from broken pieces of the honeycomb construction inside the converterĪ malfunctioning catalytic converter has to be completely replaced.Reduction in engine power from a blocked exhaust system.A sulfurous (rotten egg) smell to the exhaust from unburnt fuel in the exhaust exiting the tailpipe.Failed emissions test-a trouble code should be stored in the testing computer indicating a problem with the catalytic converter.Since other engine issues can trigger this alert, it’s important to have it checked by a professional Audi mechanic as soon as possible. Probably the most frequent symptom of catalytic converter failure is an illuminated check engine light. Incorrect ignition timing or a bad ignition coil.Common engine problems that can cause this to happen are: Remember that curb you went over?) Check your engineĬatalytic converters overheat when there is an engine issue that results in too much raw fuel being dumped into the exhaust system.

The primary cause of catalytic converter is overheating. Failure of the catalytic converter is almost always related to some malfunction in the engine. What causes premature malfunction of the catalytic converter?Ī catalytic converter generally does not malfunction in and of itself. The oxygen is also used to burn off any raw hydrocarbons remaining in the exhaust gases. In this bed, combustion of any remaining carbon monoxide is completed. The final chamber, the oxidizing bed, is coated with platinum and palladium. It stores and releases the oxygen that is freed from nitrogen in the first chamber.ģ. The function of this section is to maintain the ideal level of oxygen for use by the final section of the converter. The mid-section of the catalytic converter is known as the oxygen storage bed. It’s coated with rhodium and serves to reduce harmful nitrous oxide gases back into their individual elements of nitrogen and oxygen.Ģ. The first bed is called the reduction bed. Each bed completes a step in the process of cleaning the exhaust expelled from your car.ġ. The catalytic converter is divided into sections referred to as beds. Scrubbing the Exhaust in 3 StepsĬatalytic converters are designed to eliminate toxic gases from the vehicle’s exhaust. It’s quite common for Audi vehicles to have either 2 or 4 catalytic converters. It is shaped similar to a muffler and contains a ceramic honeycomb infused with elements that help clean the noxious exhaust gases that would otherwise be expelled from the exhaust system. The catalytic converter is an important part of your Audi exhaust system. One problem Audi owners seem to experience, though, is premature failure of their catalytic converters. The streets of Orange County are full of these trendy little automobiles.
