BMW Catalytic Converters

There are several reasons you might think you need to replace your BMW's catalytic converter. The first reason is the most obvious: your car failed to pass its emissions testing. If your BMW is putting out too many harmful emissions, the most likely culprit is a faulty or broken catalytic converter. On the other hand, you may have noticed a decrease in your BMW's performance, which can come as a result of a bad catalytic converter.

Getting Your BMW Past Emissions Tests

Many states that have pollution problems require cars to pass emissions tests every few years. While many people see this as a bureaucratic annoyance, the reality is that it does a great deal to keep our skies clean. Without the emissions laws we have on the books today, the skies around our major cities would be noticeably more polluted than they already are.

If you're driving a BMW and need a catalytic converter, it's likely that you have an older model. Newer cars (not just BMWs) rarely need a new catalytic converter, unless the converter has been physically damaged. Whatever the situation, replacing your catalytic converter is your best chance at getting your car past the required emissions tests.

One thing to keep in mind when you replace your catalytic converter is why it went bad in the first place. If the converter became clogged from overly rich exhaust, you might want to take a look at the engine itself. It's possible that your BMW has some other problems that are causing poor combustion efficiency, which can lead to higher emissions and a shorter life for your catalytic converter.
