Why is my BMW 3 Series engine making loud clicking noises?

I noticed that my BMW 3 Series engine has started making loud clicking noises while driving. What could be causing this and how can I fix it?

It is likely that your engine is experiencing a lack of lubrication, causing the clicking noises. Check your oil levels and make sure your oil is clean. If not, get an oil change and see if the noise goes away.

Another possibility is that there could be an issue with the valves in your engine. It's important to have this checked by a mechanic to avoid further damage.

If your engine is making clicking noises only when accelerating, it could be a sign of a faulty fuel injector. Have this checked by a professional to avoid any potential engine damage.
