Why is the engine of the BMW 4 Series making a rattling noise?

I recently noticed a loud rattling noise coming from the engine of my BMW 4 Series. It only happens when the car is idling or at low speeds. What could be causing this and how can I fix it?

It sounds like you may have a loose or damaged belt in your engine. I would recommend bringing it to a certified BMW mechanic to have it checked out as soon as possible.

Another possibility is that your engine is low on oil. Check your dipstick and if the oil level is low, add more and see if that solves the issue.

It could also be a problem with your catalytic converter. This can be a costly repair, so I would suggest getting a second opinion from a trusted mechanic before proceeding.
