Common Issues with the BMW 4 Series Engine

I have been experiencing some issues with my BMW 4 Series engine and I'm not sure what to do. The car seems to be running rough and there is a strange noise coming from the engine. It also doesn't seem to have as much power as it used to. What could be the problem and what can I do to fix it?

It sounds like you may have a problem with your spark plugs or ignition coils. These are known issues with the BMW 4 Series. I would recommend taking it to a certified BMW mechanic to have them check it out and replace any necessary parts. This should solve the rough running and loss of power.

Another possible issue could be a clogged fuel filter. This can cause similar symptoms and is a relatively easy fix. I would suggest having the fuel filter replaced and see if that solves the problem. If not, then you may need to look into more serious engine issues.

I had a similar problem with my BMW 4 Series and it turned out to be a faulty oxygen sensor. This can cause the engine to run lean or rich, which can lead to rough running and decreased power. Have your mechanic check the oxygen sensors and replace them if needed.
