Hello,

I’ve just taken ownership of a 2017 640d (sorry I know it’s the wrong forum but I’m guessing this is a bit more active!), under medium to hard acceleration I sometimes get this strange squeaking noise, the best way to describe it is like when you have audio cables to close together and there is interference, I have attached a video where you can just about hear it. It doesn’t happen all of the time. Has anyone ever had this or have any idea what it could be?
