What is a Catalytic Converter?

A Catalytic Converter is a metal device that is installed on the muffler of a vehicle. Its purpose is to decrease pollutants released into the atmosphere while running an internal combustion engine. They are constructed from precious metals, such as platinum, palladium, and rhodium. Although initially introduced for the United States market in the 1970s because of EPA requirements. However, others countries are beginning to mandate its installation by law. It’s because catalytic converters have done an excellent job at decreasing pollution in cities like Los Angeles, which had a severe “smog” problem.

BMW Catalytic Converter Problems

The catalytic converter on your BMW can last up to 10 years without any problems. However, there is a possibility of damage to occur from contaminants, overheating, clogging or an accident. But how do you know that there is something wrong?

1. Engine performance decreased. If you feel that the performance of your engine is not what it used to be, it could be the catalytic converter. Since it is connected directly to the exhaust, if it is clogged or cracked, it would seriously affect your vehicle’s performance.
2. Rattling sound. You might only hear this sound when starting the car, but it will get worse over time. Rattling happens because old age and use causing the mesh inside to collapse. Watch out for any rattling noises, and get your vehicle’s catalytic converter inspected.
3. Check engine light is on. Although the check engine light may turn on for any reason, there are tools you can use to find out why. You can learn more about using a scanning tool to check for error codes here. But there are multiple sensors that help make the catalytic converter work correctly, so it’s best to have a diagnosis done.

Since catalytic converters are made from precious metals such as platinum, palladium, and rhodium, they are susceptible to theft. There was a 25% increase in the number of thefts reported in 2015 compared to 2008. To reduce the risk of this type of theft park in well-lit areas, and attempt some additional welding.
