Turbo noise when hard on throttle
Ok, so i just picked up a 2013 F10 M5 and it basically looks brand new. Has 1200 miles on it and i am noticing a slight buzzing noise coming from the turbos when hard on the throttle. Is this normal? Anyone else hearing this? I was thinking of bringing it in and getting it checked but wanted to make sure i wasnt paranoid first as this is my first non NA engine car and i am not familiar with the sounds the turbos should be putting out.

With the windows down when I punch it you can hear the sucking/spooling sound of the turbos. Kind of high pitched, stops as soon as you let up on throttle.

I just purchased 13 M5 as well and hear a buzzing,whirring, electrical like noise at low speeds with window down. It is more noticable when the car is cold and seems to dissipate when warm? I took it to service, at first they couldnt hear anything so they eventually made me do a ride along and the sound was very clear. The mechanic said it is normal sound coming from engine? I am not convinced its normal, but whatya do??

Bad ground or loose connection ? Do you any equipment added to your car like a laser jammer, radar detector or exhaust mister. if they are not grounded properly it could do this.

Bmw said the noise is normal from a high performance engine and is not a concern? It does not sound normal to me, It sounds like a bad alternator or?
