Only joking. Car was running fine. Was just wondering(not worrying) what the whirring noise is that comes from the rear after driving it for about 1hour. Sounds like a fan? And the car is stationary.
Sounds like pressure in the fuel tank. I posted a similar question shortly after buying mine! Release the fuel cap (very, very slowly) and allow it to vent for a minute or so, then close. This should relieve the pressure and stop the noise.........
