Hello!
When I drive with hood up in our 4/4, I find it very noisy and popping sounds appear when the speed is close to 65 mph.
My dealer tells me to open the side screens to get rid of the popping sound, but it is still there.
I find it less noisy in even higher speeds with the hood down.
Is there a solution to get a nice ride with hood up?
Regards, Bosse
