There could be several reasons for your engine making a strange noise. It could be something as minor as a loose piece of debris rattling around, or something more serious like engine damage. It's always better to be safe than sorry, so I would recommend taking your car to a BMW certified technician for a proper diagnosis and repair.

I had a similar issue with my BMW 6 Series and it turned out to be a faulty belt tensioner. I would suggest checking that first as it is a common issue with these cars. If the noise persists, definitely have it checked out by a professional.

I work for BMW and have seen this issue before. The problem could be with the timing chain, which can cause the engine to make a knocking noise. It's important to have this addressed right away as it can lead to further damage. I recommend bringing it to a BMW dealership for a thorough inspection and repair.
