Why is my BMW 3 Series engine making loud noises?

I have a 2015 BMW 3 Series and recently the engine has been making loud rattling noises. It seems to be coming from under the hood and it's happening even when the car is idling. What could be causing this and how can I fix it?

Hi Alex, the most likely cause for your engine making loud noises is a problem with the exhaust system. It could be a loose or damaged part such as the muffler or the catalytic converter. I recommend taking your car to a mechanic to have it checked and repaired if needed.

Hey Alex, another possible cause could be an issue with the engine itself, such as worn out engine bearings or a faulty timing belt. This type of problem usually requires professional repair, so it's best to bring your car to a trusted mechanic for a thorough diagnosis.
