Why is my BMW 5 Series making a strange noise when I start it?

I recently noticed that my BMW 5 Series is making a strange noise when I start it up in the morning. It's a bit concerning as it seems to be coming from the engine. Has anyone experienced this before? Any advice on what could be causing it and what steps I should take?

Hi Sarah, it's important to get this checked out by a mechanic as soon as possible. It could be an issue with the starter or the alternator, or possibly a loose belt. Don't ignore it as it could lead to bigger and more expensive problems down the line.
