So Iv'e had this issue from day 1 and it's concerning. There is a high pitched metallic pinging noise that emits from the front of the engine bay whether the car is cold or I'm driving then idling. I have heard this sound in other BMWs and I believe this video is the closest in similarity. I dont understand how a new car can have bearings shot in the tensioner pully already. 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?
