Why does my BMW M5 engine rattle when I accelerate?

I've noticed that when I press on the gas pedal, my BMW M5's engine makes a rattling sound. It seems to go away after a few seconds or when the car reaches a certain speed. What could be causing this and how can I fix it?

Hi Mike, this rattling sound could be caused by a number of issues. It could be a loose exhaust manifold, worn serpentine belt, or even a faulty catalytic converter. It's best to take your BMW to a certified mechanic to diagnose the exact cause.

I had a similar issue with my M5 and it turned out to be a problem with the ignition coils. Replacing them solved the rattling sound for me. Make sure to have a professional inspect your car to determine the root cause.
