BMW 530i Catalytic Converters

The catalytic convertor under the hood of your BMW 530i is something that helps to take the fumes generated during the combustion process and convert them into harmless gases that are able to be expelled from your vehicle. This helps to reduce the amount of pollution going into the air from your exhaust. The converter changes the chemical makeup of the fumes through a chemical reaction. The catalytic convertor is built to last a long time, but this doesn't mean problems can't occur. Knowing signs of wear and tear on the convertor is important so you are able to get a replacement if needed. The check engine light might come on - which can mean a lot of things, but it's worth checking the convertor. Smelling sulfates or a "rotten egg" smell might be an indication of a clogged catalytic convertor. A noticeable decrease in gas mileage can also be a sign.
