Audi has a long history of manufacturing quality German cars which ooze sophistication and luxury while still being practical when it comes to the rigors of day to day life. Sleek and comfortable yet efficient and a pleasure to drive, there really are a lot of reasons to be happy if you’re an Audi driver.

However, amid the recent emissions scandals, some faith has been lost in Audi as a brand. Loyal Audi owners are being more responsible than ever when it comes to the condition of their vehicles, particularly surrounding emissions. With this in mind, in this article, we will take a look at your Audi’s catalytic converter, learn what it is, what can cause failure, and discuss symptoms that tell you when it’s time to get your catalytic converter replaced.

What is a catalytic converter?

Did you know you have a mini chemistry lab in your Audi’s exhaust pipe? Otherwise known as the catalytic converter, this tiny chemical factory is one of the most essential parts of your entire car. It is the job of the catalytic converter to turn the dangerous emissions created by your engine into safer exhaust emissions.

Your catalytic converter is a canister that typically contains a mixture of palladium and platinum. These create reactions which transform harmful gases into safer ones. Therefore, the catalytic converter is responsible for ensuring your vehicle is safe for you, those around you, and the environment as a whole. If this part fails, your Audi can become unsafe and very harmful.

What can cause my catalytic converter to fail?

The catalytic converter is designed to last the entire lifespan of your vehicle. However, given the right conditions, this part can deteriorate prematurely. High mileage and an improperly operating engine all take a toll on the converter, wearing out the chemical elements needed for successful reactions. Listed below are the key parts that can place an extra toll on the catalytic converter if they fail:

• Spark plugs
• Burned/leaking exhaust valves
• Weak ignition system
• Worn piston rings
• Jumped timing chain
• Head gasket leak
• Intake manifold leak

What are the signs of catalytic converter failure?

There are five key symptoms of a failed catalytic converter. Being aware of these symptoms will help you know when you should take your Audi into the shop for a replacement.

1. Reduction in Engine Performance: If your catalytic converter is failing, you’ll notice reduced engine performance. A failed catalytic converter can reduce exhaust flow as well as cause harmful gases to leak, both of which can cause a reduction in power, acceleration, and fuel economy.
2. Rattling Noise: Rattling noises coming from under your Audi can also signal your catalytic converter needs changing. This rattling is caused by the catalysts breaking apart, coming loose, and then causing a rattle as your vehicle moves. Typically the rattle will worsen over time, as more and more of the catalyst breaks down.
3. Rotten Egg Smell: If you smell sulphur coming from your exhaust, this could be a clear sign that you need a new converter. Sulphur smells like rotten eggs. This stench means that your converter isn’t correctly converting exhaust fumes.
4. Check Engine Light Illuminates: There can be many reasons as to why your check engine illuminates, with just one of those being a faulty catalytic converter. This light illuminates when the onboard computer has become aware of the issues with the converter. It is the main way your vehicle will alert you to this type of issue.
5. Emissions Test Failure: If your catalytic converter isn’t working, then it’s almost a guarantee that your Audi will fail its emissions tests. If the converter isn’t working properly, it is likely an increased rate of bad emissions will slip through the exhaust, resulting in a higher level of toxicity in emissions and test failure. This also means it is a potential danger to you and those around you.
