Hello forum members,
I have a 2012 BMW M6 (F12), with Mission Performance stage 1 tune.
In the past 200 miles, I have an experienced a high pitched squeaking/squealing noise, especially in the beginning of the engine warmup phase. After the car warms up, the noise stops. When I open the front hood, I can barely hear it, but I can hear it more underneath the vehicle. The sound increases in tempo when the throttle is pressed. It isn't impacting the vehicles performance... at least none that I noticed.
I am posting 3 videos, to see if I could get some feedback.
