Your BMW 530i oxygen sensor is an important part of your car's combustion system. When your car exhibits a decrease in fuel economy, there are several possibilities regarding the cause, but a faulty 530i oxygen sensor is a likely culprit. You will find your BMW 530i oxygen sensor mounted near the exhaust manifold, where it works together with a network of sensors to monitor the oxygen content of your exhaust.

This is important because your car relies on a mixture of fuel and oxygen to power the engine. The 530i oxygen sensor ensures that your car's computer is able to calculate the amount of fuel that must be injected into the combustion chambers.

Your BMW 530i oxygen sensor accomplishes this by measuring the amount of oxygen in the exhaust that is exiting your cylinders hundreds of times, and relaying that data to the on-board computer. Since the 530i oxygen sensor is the only sensor found near the manifold, when it is not working properly your car must rely on the estimates of other sensors. Typically, a faulty BMW 530i oxygen sensor will force your car to inject too much fuel, because too little fuel can damage other engine parts. The "rich" fuel mixture that results from a bad 530i oxygen sensor will damage your catalytic converter over time as excess fuel moves through the exhaust system.
