Firstly, check your spark plugs and ignition coils, as they are common culprits for engine noises in BMW 3 Series. If they seem fine, then it could be an issue with your fuel injectors or valves. I recommend taking your car to a certified mechanic for a thorough diagnosis and proper repair.

It could be a problem with your timing belt or timing chain. If they are worn out or damaged, they can cause unusual engine noises. It's important to get these components checked and replaced if necessary, as they are crucial for the proper functioning of your engine.
