BMW X3 is a compact luxury crossover SUV that is produced by German car maker BMW. Its production began in 2003. BMW X3 appeals to drivers with high-quality parts, such as the catalytic converter. A faulty catalytic converter can lead to poor engine performance, rattling noises in the engine, and engine misfires.
BMW X3 stands out for its great parts. But the catalytic converter still needs repair and maintenance after a long time of usage. Signs of a bad BMW X3 catalytic converter include poor engine performance, black exhaust smoke, a bad smell from the exhaust, and the check engine light on the dashboard. The catalytic converter is typically made out of platinum, rhodium, and palladium. Sometimes it is made of gold. Customers could get performance products every day online.
