This is my first BMW and I was hoping someone who has experienced this can chime in. I have my first service scheduled in 2 weeks, any suggestions for my mechanic?

Have you ever owned a Direct injected car?
Injector pulse is loud and can sound metallic like that. I would doubt it's the tensioner, but you never know!
