SO my 2000 M5 broke down the other day and I had it towed to my house. When it broke down it basically stalled out and refused to drive. After I got it home a couple days later I went to turn it on and it started making a really loud rattling noise from the engine. If any one has any ideas or suggestions please feel free to tell me what you think. Thanks a lot. Below is a video of the sound.
