BMW 3 Series Catalytic converter replacement
Why does my BMW 3 Series catalytic converter need to be replaced?
If your BMW 3 Series has an internal combustion engine (ICE) it will have a catalytic converter.
The catalytic converter minimizes the pollutants that exit your tailpipe whenever your engine is running.
Catalytic converters are part of the exhaust system. When the engines toxic gases enter the catalytic converter they convert to less toxic pollutants, due to a reaction that occurs inside the catalytic converter.
Your BMW 3 Series will run without a catalytic converter however due to environmental regulations it is not legal to do so and you can be fined. They are a useful tool to reduce harmful pollutants from entering the environment.
If your BMW 3 Series catalytic converter is faulty you may notice a bad smell coming from the exhaust, or a rattly noise under the car. If the catalytic converter is clogged up the exhaust gases can't escape and it will cause issues with the drivability of the vehicle, lack performance, fuel consumption will increase and the car might not run at all.
Other running problems can cause the catalytic converter on your BMW 3 Series to fail, and it may need to be replaced. If that happens, it’s good to know AutoGuru!
