Has anyone noticed a steady high pitched noise coming from rear of the car when driving? .My car is 2015 Z51 3LT A8 .
Have not been able to pinpoint the source . My hearing frequency range is apparently not as good as the wife but there are no obvious issues mechanically, no vibrations . no error codes electronically .Question `did you ever figure out noise, my wife hears the same thing in our Z51, thx Kevin
