How to resolve a sudden loss of power in a BMW 4 Series?

I was driving my BMW 4 Series when suddenly it lost power and began to slow down. How can I fix this issue and prevent it from happening again?

First, check the air filter to see if it needs to be replaced. A clogged air filter can cause a reduction in power. If that doesn't solve the issue, it could be an issue with the fuel system. It's best to take your car to a certified mechanic for a thorough inspection and repairs.

This could be a result of a faulty oxygen sensor. When the oxygen sensor is not functioning properly, the engine may not receive enough fuel, leading to a loss of power. Take your car to a mechanic to have the oxygen sensor checked and replaced if necessary.
