Why is my BMW 4 Series producing unusual engine noises?

I have recently noticed that my BMW 4 Series is making strange noises when the engine is running. What could be causing this issue and how can I fix it?

There could be several reasons for unusual engine noises in your BMW 4 Series. One possible cause could be a problem with the timing chain or tensioner. It is important to have this checked and repaired by a certified mechanic to avoid any further damage to your engine.

Another possible cause could be low oil levels or dirty oil. Make sure to regularly check and change your engine oil to keep it running smoothly and avoid any potential issues.

Sometimes unusual engine noises can also be caused by faulty spark plugs or ignition coils. These should be inspected and replaced if necessary to prevent any potential engine problems.
