Interchange Part Number : 23211Series : Standard SeriesTube Material : Aluminized SteelOver time, your Volkswagen Passat catalytic converter can get worn out due to external factors like road debris and corrosion or due to some engine issues. Once your catalytic converter fails, the performance of your ride can be compromised because the unburned gases will not be able to exit from your vehicle. Hence, you must be aware of the warning signals that can indicate a possible replacement of your Volkswagen Passat catalytic converter. Listed here are some issues that you must be aware of:
Rattling noise
You can hear this noise when you are driving or when you have removed your catalytic converter for inspection. Rattling noise is an indication that your catalytic converter is possibly failing. This is because once dirt and other road debris find their way to your catalytic converter, they can cause its inner ceramic catalyst to get damaged. This situation is also called as catalyst fracture. Once this happens, the pieces from the ceramic catalyst that got broken will eventually end up becoming smaller. As a result, they will rattle inside your catalytic converter.
Decrease in fuel economy
If you start to notice that you are not going faster than what you have expected upon stepping on the gas pedal, then your catalytic converter is encountering problems. This is because once your catalytic converter starts to fail or wear out, it will not be able to act upon the unburned exhaust gases properly. As a result, the toxic gases can remain clogged in it. These gases will then cause the performance of the engine to depreciate while running because they cannot exit your vehicle.
Visible carbon build-up
If you notice that there is excessive carbon build-up from the exhaust, which comes in the form of a dark smoke, then it possibly means that your catalytic converter needs to be replaced immediately. This is because once the antifreeze leaks on the catalytic converter, its harsh chemicals can affect the performance of your catalytic converter. If your catalytic converter starts to malfunction because of this, it can let excessive carbon to come out from the exhaust.
Catalytic converters were designed to last the Volkswagen Passat's lifetime. With proper maintenance and use, it should at least last for 50,000 miles or 5 years. Modern cars and trucks have catalytic converters that can last up to 80,000 miles or 8 years. Catalytic converters are integral parts of the vehicle's engine and exhaust system, to achieve the lowest possible emissions.
Catalytic converters do not have mechanical working parts in them. Its function is to filter the harmful emissions before it's released into the atmosphere. Poor installation can cause a catalytic converter to fail. Sometimes, the converter's gaskets have not been replaced during installation. Using fuel and engine additives, which are not oxygen-sensor safe, can also contribute to a catalytic converter's failure. Poor engine maintenance can also affect the performance of your catalytic converter. Physical damage, like dents or cracks, is the most common reason why a catalytic converter breaks down.
There are two types of catalytic converters available for a Volkswagen Passat: the common catcon or the two-way version and the high-end catcon, or the three-way version. A common cat converter offers the simplest process and it’s widely available. High-end converters on the other hand, are designed for leaner engines to maximize their efficiency. It’s important to know the right catalytic converter before installing a new one on the Volkswagen Passat.
One of the most common signs that you need to change the Volkswagen Passat's catalytic converter is when the car refuses to start. When the catalytic converter becomes so clogged, the exhaust gases can't pass through it and the engine eventually dies. Oil or coolant leaks can also contaminate the ceramics inside the catalytic converter's chamber, causing it to clog. Another reason is when you have a faulty oxygen sensor; it can alter the engine's air/fuel mixture damaging the catalytic converter. Also, when the car fails the emissions test, it's time to replace the catalytic converter.
