Had anyone experienced the follows (I've booked to be checked up next month when I'm out of town, but anyways) on a 1-2 yrs MS. 1) Ventilation is open between level 5 and like 10 (I thought they updated the software so its open =<4). I normally like to run the AC at 6-7 but in and near tunnels where there is always a jam I get a lot of outside air. Then i need to run the AC up to 10/11 to ensure the air is kept out. 2) AC noise. Esp in summer i need to run it high (higher than 6-7...) The car is too quiet and most of the noise inside is AC. lol. 3) compressor not running. maybe its the thermostat cuz i've kept the car cold enough so ventilation is open - then air gets humid. Run it up to 10-11 then no problem.
