I took the car back to the dealer and they ran a diagnostics check but we’re unable to detect any fault. The salesman could hear the crackling and thought it was probably just a trait of the car but he didn’t have another 8 Series with the B&W Hi-Fi to see if the issue was common to all cars.

Has anyone else come across this issue?

Many thanks

I'll check in mine but if it's there I haven't noticed it in a year.
