Hey folks,

I’ve got a g80 m3 comp x drive. Upon cold start when the rpm dip I notice a buzzing/rattling sound. The sound is pretty evident after 30 seconds in the video. Have any of you had exprience with this sound? If so what is it and is it normal?

Advice is to switch off air con completely and see if the noise is still there. Could be related to that system, if so I would ignore or try warranty claim.

Hope you narrow it down. Mine is 2 years old with around 7k miles and does not make that sound.
