Hi. Folks. I have an Range rover P38 4.0SE Automatic 1996. Many time i hear a ruumor in the middle of the car, when is in the parking or in the neutral. The rumor is a littel hard and i can hear even with closed windows. The rumor stay for 3 or 4 second and disapire. After a while the rumore come again . What is that??? Everythings run normal. No problem in general.
