Hi,
I am new here and just got my first bmw used 535i a month ago. I think the engine emits some kind[/B] of hollow noise, like the injector sound speed but it's not them. It's more like something made of plastic with the speed of the injectors noise. I recorded the noise with my phone and if someone that has this engine can tell me if it's normal or not? I took the car to the dealer and they said no abnormal sounds made by engine. It is very noticeable when idle. On the recording focus on that hollow moving sound. Thank you and hope someone can help me.
