Signs of a Clogged Catalytic Converter in an Audi

Posted on | 8 Jul 2018 By Anita Gaal

What is a catalytic converter’s main function?

Found on the under side of the car, the catalytic converter plays an important function in your Audi’s performance; however, it is highly susceptible to clogs as well as external damage from accidents, road imperfections, or driving a little too quickly over speed bumps. As a part of your car’s exhaust system, the catalytic converter is responsible for shifting the chemical makeup of your car’s exhaust emissions before it is released into the atmosphere. In an effort to reduce harmful gas emissions, catalytic converters or similar devices are required in all cars. Catalytic converters are designed to last the life of your vehicle; unfortunately, damage and failure can still occur. When your catalytic converter becomes damaged or fails, it can cause your car to exhibit particular symptoms that you should be aware of and follow up on with your Audi specialist.

Signs that your Audi’s catalytic converter is failing

Because the catalytic converter has such a huge hand in the exhaust system, a lot of the symptoms drivers tend to experience when a clog or other damages occur are related to exhaust and emissions problems. These are the top most common symptoms related to catalytic converter failure:

Engine misfiring

While not necessarily a direct symptom of a clogged catalytic converter, engine misfiring can be a comorbid symptom that can eventually lead to an overheating converter. Engine misfiring is problematic and unsafe, and should be addressed by a professional right away.

Emissions problems

A clogged or failed catalytic converter will not be able to effectively eliminate the harmful gasses from your vehicle’s emissions, often leading to failed emissions tests or chemical-like smells coming from your exhaust.

Performance changes

Your engine’s air intake and exhaust system work effectively together to draw air in and the push it out. When the catalytic converter becomes clogged or fails, it can lead to a pressure buildup in the system which makes it difficult for your intake and exhaust system to work effectively. This can lead to significant changes in your Audi’s performance, including rough acceleration.

Lowered fuel efficiency

When the flow of the air through the engine and out through the exhaust becomes impeded by a clogged or damaged converter, it can lead to diminished fuel efficiency. This is concerning for drivers, as most Audi vehicles have excellent fuel economy.

Rattling sounds

A rattling sound coming from the catalytic converter may mean the difference between a clog and damage. A clog will likely be able to be fixed, but depending on the extend of damage accrued, the converter may need to be replaced all together.

Check-engine light is on

If your check-engine comes on for any reason, it is critical to bring it to an Audi specialist right away to read the trouble codes and properly diagnose the problem. Your check-engine light can illuminate for a number of reasons, and they’re all important to treat with efficiency; however, if the emissions system has encountered a clog in the converter, the problem can worsen quickly.

How to ensure your catalytic converter remains intact

As a responsible car owner, there are a few things you can do for your Audi to make sure the catalytic converter remains intact in the coming years. Here are a few simple guidelines to follow for the best performance results:
